AngularJS ng-bind-html 2way 数据绑定 [英] AngularJS ng-bind-html 2way data binding

问题描述

我有一个 AngularJS 应用程序，我从网络服务中获取了一些数据，并使用 ng-bind-html 将一些 HTML 解析为模板......但是当我尝试在 ng-bind-html 中绑定数据时 - 什么也没有发生.. 任何人?

我这里有一个小例子，.. 不是正确的情况.

HTML

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

Javascript

angular.module('myApp',[]).controller('MyCtrl', function($scope, $sce) {$scope.name = '世界';$scope.post = $sce.trustAsHtml("<h1>hello {{name}}</h1>");});

解决方案

DEMO

添加此指令

angular.module("myApp").directive('compileTemplate', ["$compile", "$parse", function($compile, $parse) {返回 {限制:'A'，链接:函数($scope，元素，属性){var parse = $parse(attr.ngBindHtml);function value() { return (parse($scope) || '').toString();}$scope.$watch(value, function() {$compile(element, null, -9999)($scope);});}}}]);

I have an AngularJS app where I got some data from a webservice and parse some HTML to the template with ng-bind-html ... but when I try to bind data inside the ng-bind-html - nothing happens .. anyone?

I have a little example here,.. not the right case.

HTML

<div ng-controller="MyCtrl">
    <div ng-bind-html="post"></div>
</div>

Javascript

angular.module('myApp',[])
.controller('MyCtrl', function($scope, $sce) {
    $scope.name = 'World';
    $scope.post = $sce.trustAsHtml("<h1>hello {{name}}</h1>");
});

解决方案

Add this directive

angular.module("myApp").directive('compileTemplate', ["$compile", "$parse", function($compile, $parse) {
    return {
        restrict: 'A',
        link: function($scope, element, attr) {
            var parse = $parse(attr.ngBindHtml);
            function value() { return (parse($scope) || '').toString(); }

            $scope.$watch(value, function() {
                $compile(element, null, -9999)($scope); 
            });
        }
    }
}]);
