AngularJS: API: ngSanitize/service/$sanitize

$sanitize

- service in module ngSanitize

The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are then serialized back to properly escaped html string. This means that no unsafe input can make it into the returned string, however, since our parser is more strict than a typical browser parser, it's possible that some obscure input, which would be recognized as valid HTML by a browser, won't make it through the sanitizer. The whitelist is configured using the functions aHrefSanitizationWhitelist and imgSrcSanitizationWhitelist of $compileProvider.

用法

$sanitize(html);

参数

参数	类型	详述
html	string	Html input.

返回值

string

Sanitized html.

示例

index.html

    angular.module('sanitizeExample', ['ngSanitize'])
      .controller('ExampleController', ['$scope', '$sce', Function($scope, $sce) {
        $scope.snippet =

        $scope.deliberatelyTrustDangerousSnippet = Function() {
          return $sce.trustAsHtml($scope.snippet);
