AngularJS: API: ng/directive/ngBindHtml
ngBindHtml
- - directive in module ng
创建一个绑定，使用安全的方式使当前元素的innerHTML为 expression 的计算结果。默认情况下，innerHTML中的内容会使用 $sanitize 服务进行净化。为使用这个功能，确保 $sanitize 有效，例如，包含 ngSanitize 到你的模块依赖中 (它不在 Angular核心中)。如果你知道值是安全的，你也可以忽略净化。如要这样做，需要通过 $sce.trustAsHtml来绑定一个明确可信的值。 请参见Strict Contextual Escaping (SCE)下的例子。
注意：如果 $sanitize 服务无效，并且绑定的值不是明确可信的，你将得到一个错误（而不会使用它）。

index.html
<div ng-controller="ExampleController">
<p ng-bind-html="myHTML"></p>
</div>angular.module('bindHtmlExample', ['ngSanitize'])
.controller('ExampleController', ['$scope', Function($scope) {
$scope.myHTML =
'I am an <code>HTML</code>string with ' +
'<a href="#">links!</a> and other <em>stuff</em>';
}]);it('should check ng-bind-html', Function() {
expect(element(by.binding('myHTML')).getText()).toBe(
'I am an HTMLstring with links! and other stuff');});
