to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding ``
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ *
+ *
+ *
+ *
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings. (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context. You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc. You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this. Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
+ * ng.$sce#parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
+ * simplified):
+ *
+ *
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ * return function(scope, element, attr) {
+ * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ *
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead for the developer?
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `
`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document. You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ *
+ * ## What trusted context types are supported?
+ *
+ * | Context | Notes |
+ * |---------------------|----------------|
+ * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
+ * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
+ * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist}
+ *
+ * Each element in these arrays must be one of the following:
+ *
+ * - **'self'**
+ * - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ * domain** as the application document using the **same protocol**.
+ * - **String** (except the special value `'self'`)
+ * - The string is matched against the full *normalized / absolute URL* of the resource
+ * being tested (substring matches are not good enough.)
+ * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
+ * match themselves.
+ * - `*`: matches zero or more occurrences of any character other than one of the following 6
+ * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use
+ * in a whitelist.
+ * - `**`: matches zero or more occurrences of *any* character. As such, it's not
+ * not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g.
+ * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ * not have been the intention.) Its usage at the very end of the path is ok. (e.g.
+ * http://foo.example.com/templates/**).
+ * - **RegExp** (*see caveat below*)
+ * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
+ * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
+ * accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ * have good test coverage.). For instance, the use of `.` in the regex is correct only in a
+ * small number of cases. A `.` character in the regex used when matching the scheme or a
+ * subdomain could be matched against a `:` or literal `.` that was likely not intended. It
+ * is highly recommended to use the string patterns and only fall back to regular expressions
+ * if they as a last resort.
+ * - The regular expression must be an instance of RegExp (i.e. not a string.) It is
+ * matched against the **entire** *normalized / absolute URL* of the resource being tested
+ * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
+ * present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ * - If you are generating your JavaScript from some other templating engine (not
+ * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ * remember to escape your regular expression (and be aware that you might need more than
+ * one level of escaping depending on your templating engine and the way you interpolated
+ * the value.) Do make use of your platform's escaping mechanism as it might be good
+ * enough before coding your own. e.g. Ruby has
+ * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ * Javascript lacks a similar built in function for escaping. Take a look at Google
+ * Closure library's [goog.string.regExpEscape(s)](
+ * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.
+ *
+ * ## Show me an example using SCE.
+ *
+ * @example
+
+
+
+
+
User comments
+ By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
+ $sanitize is available. If $sanitize isn't available, this results in an error instead of an
+ exploit.
+
+
+ {{userComment.name}}:
+

+
+
+
+ *
+ *
+ *
+ * ## Can I disable SCE completely?
+ *
+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ *
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ * // Completely disable SCE. For demonstration purposes only!
+ * // Do not use in new projects.
+ * $sceProvider.enabled(false);
+ * });
+ *

+ /* Design notes on the default implementation for SCE.
+ *
+ * The API contract for the SCE delegate
+ * -------------------------------------
+ * The SCE delegate object must provide the following 3 methods:
+ *
+ * - trustAs(contextEnum, value)
+ * This method is used to tell the SCE service that the provided value is OK to use in the
+ * contexts specified by contextEnum. It must return an object that will be accepted by
+ * getTrusted() for a compatible contextEnum and return this value.
+ *
+ * - valueOf(value)
+ * For values that were not produced by trustAs(), return them as is. For values that were
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
+ * such a value.
+ *
+ * - getTrusted(contextEnum, value)
+ * This function should return the a value that is safe to use in the context specified by
+ * contextEnum or throw and exception otherwise.
+ *
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
+ * return the same object passed in if it was found in the registry under a compatible context or
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
+ *
+ *
+ * A note on the inheritance model for SCE contexts
+ * ------------------------------------------------
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
+ * is purely an implementation details.
+ *
+ * The contract is simply this:
+ *
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+ * will also succeed.
+ *
+ * Inheritance happens to capture this in a natural way. In some future, we
+ * may not use inheritance anymore. That is OK because no code outside of
+ * sce.js and sceSpecs.js would need to be aware of this detail.

+/**
+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL. This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
+ * properties such as protocol, hostname, port, etc.
+ *
+ * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one
+ * uses the inner HTML approach to assign the URL as part of an HTML snippet -
+ * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL.
+ * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
+ * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
+ * method and IE < 8 is unsupported.

+ * return function(text) {
+ * // filters need to be forgiving so check input validity
+ * return text && greet(text) || text;
+ * };

+ *
+ * The filter function is registered with the `$injector` under the filter name suffix with

+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ * `array`.
+ *
+ * Can be one of:
+ *
+ * - `string`: The string is evaluated as an expression and the resulting value is used for substring match against
+ * the contents of the `array`. All strings or objects with string properties in `array` that contain this string
+ * will be returned. The predicate can be negated by prefixing the string with `!`.
+ *
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ * which have property `name` containing "M" and property `phone` containing "1". A special
+ * property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ * property of the object. That's equivalent to the simple substring match with a `string`
+ * as described above.
+ *
+ * - `function(value)`: A predicate function can be used to write arbitrary filters. The function is
+ * called for each element of `array`. The final result is an array of those elements that
+ * the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ * determining if the expected value (from the filter expression) and actual value (from
+ * the object in the array) should be considered a match.
+ *
+ * Can be one of:
+ *
+ * - `function(actual, expected)`:
+ * The function will be given the object value and the predicate value to compare and
+ * should return true if the item should be included in filtered result.
+ *
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`.
+ * this is essentially strict comparison of expected and actual.
+ *

+ * Formats `date` to a string based on the requested `format`.
+ *
+ * `format` string can be composed of the following elements:
+ *
+ * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ * * `'MMMM'`: Month in year (January-December)
+ * * `'MMM'`: Month in year (Jan-Dec)
+ * * `'MM'`: Month in year, padded (01-12)
+ * * `'M'`: Month in year (1-12)
+ * * `'dd'`: Day in month, padded (01-31)
+ * * `'d'`: Day in month (1-31)
+ * * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ * * `'EEE'`: Day in Week, (Sun-Sat)
+ * * `'HH'`: Hour in day, padded (00-23)
+ * * `'H'`: Hour in day (0-23)
+ * * `'hh'`: Hour in am/pm, padded (01-12)
+ * * `'h'`: Hour in am/pm, (1-12)
+ * * `'mm'`: Minute in hour, padded (00-59)
+ * * `'m'`: Minute in hour (0-59)
+ * * `'ss'`: Second in minute, padded (00-59)
+ * * `'s'`: Second in minute (0-59)
+ * * `'.sss' or ',sss'`: Millisecond in second, padded (000-999)
+ * * `'a'`: am/pm marker
+ * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ *
+ * `format` string can also be one of the following predefined
+ * {@link guide/i18n localizable formats}:
+ *
+ * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ * (e.g. Sep 3, 2010 12:05:08 pm)
+ * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 pm)
+ * * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US locale
+ * (e.g. Friday, September 3, 2010)
+ * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
+ * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
+ * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
+ * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
+ * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
+ *
+ * `format` string can contain literal values. These need to be quoted with single quotes (e.g.
+ * `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
+ * (e.g. `"h 'o''clock'"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
+ * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ * specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ * `mediumDate` is used.
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

+ * such as open. (Their presence means true and their absence means false.)
+ * If we put an Angular interpolation expression into such an attribute then the
+ * binding information would be lost when the browser removes the attribute.
+ * The `ngOpen` directive solves this problem for the `open` attribute.
+ * This complementary directive is not removed by the browser and so provides
+ * a permanent reliable place to store the binding information.
+ * @example
+
+
+ Check me check multiple:
+
+ Show/Hide me
+
+
+
+ it('should toggle open', function() {
+ expect(element(by.id('details')).getAttribute('open')).toBeFalsy();
+ element(by.model('open')).click();
+ expect(element(by.id('details')).getAttribute('open')).toBeTruthy();
+ });
+
+
+ *
+ * @element DETAILS
+ * @param {expression} ngOpen If the {@link guide/expression expression} is truthy,
+ * then special attribute "open" will be set on the element
