在Angular 1.2+中如何使用$sce.trustAsHtml(string)来复制ng-bind-html-unsafe

ng-bind-html-unsafe在Angular 1.2中被移除

我试图实现的东西，我需要使用ng-bind-html-不安全。在文档和github提交中，他们说:

ng-bind-html提供了ng-html-bind-不安全的行为(innerHTML的结果没有当绑定到$sce.trustAsHtml(string)的结果时，sanitization)。

怎么做呢?

当前回答

就我个人而言，在进入数据库之前，我会用一些PHP库对我的所有数据进行消毒，这样我就不需要另一个XSS过滤器了。

来自AngularJS 1.0.8

directives.directive('ngBindHtmlUnsafe', [function() {
    return function(scope, element, attr) {
        element.addClass('ng-binding').data('$binding', attr.ngBindHtmlUnsafe);
        scope.$watch(attr.ngBindHtmlUnsafe, function ngBindHtmlUnsafeWatchAction(value) {
            element.html(value || '');
        });
    }
}]);

使用方法:

<div ng-bind-html-unsafe="group.description"></div>

禁用$sce:

app.config(['$sceProvider', function($sceProvider) {
    $sceProvider.enabled(false);
}]);

这应该是:

<div ng-bind-html="trustedHtml"></div>

在你的控制器中:

$scope.html = '<ul><li>render me please</li></ul>';
$scope.trustedHtml = $sce.trustAsHtml($scope.html);

而不是旧的语法，你可以直接引用$scope.html变量:

<div ng-bind-html-unsafe="html"></div>

正如一些评论者指出的那样，$sce必须注入到控制器中，否则将得到$sce undefined错误。

 var myApp = angular.module('myApp',[]);

 myApp.controller('MyController', ['$sce', function($sce) {
    // ... [your code]
 }]);

对于Rails(至少在我的情况下)，如果你正在使用angularjs-rails gem，请记得添加sanitize模块

//= require angular
//= require angular-sanitize

然后在你的应用程序中加载它…

var myDummyApp = angular.module('myDummyApp', ['ngSanitize']);

然后您可以执行以下操作:

在模板中:

%span{"ng-bind-html"=>"phone_with_break(x)"}

最后:

$scope.phone_with_break = function (x) {
  if (x.phone != "") {
   return x.phone + "<br>";
  }
  return '';
}

如果你想要回到旧的指令，你可以添加这个到你的应用程序:

指令:

directives.directive('ngBindHtmlUnsafe', ['$sce', function($sce){
    return {
        scope: {
            ngBindHtmlUnsafe: '=',
        },
        template: "<div ng-bind-html='trustedHtml'></div>",
        link: function($scope, iElm, iAttrs, controller) {
            $scope.updateView = function() {
                $scope.trustedHtml = $sce.trustAsHtml($scope.ngBindHtmlUnsafe);
            }

            $scope.$watch('ngBindHtmlUnsafe', function(newVal, oldVal) {
                $scope.updateView(newVal);
            });
        }
    };
}]);

使用

<div ng-bind-html-unsafe="group.description"></div>
