在AngularJS上将文本渲染为HTML

我试图在表格中显示文本字段(如表单)。我有一个按钮,当我点击它时,一个新行被添加到表中,所有单元格都是表单字段。当我单击按钮时,会出现一个新行(确定),但是,字段的html代码显示为文本。我尝试渲染为html,但它不起作用:

1。Render text as html with angularJs 2。AngularJS : Insert HTML into view 3。http://fdietz.github.io/recipes-with-angular-js/common-user-interface-patterns/editing-text-in-place-using-html5-content-editable.html]

我已经完成了一个index.html,它为不同的观点提供了3条路线。索引文件包含所有角度sripts和我自己的脚本。我正在寻找最简单的方法。这是我第一次使用angular。

的index.html:

<html ng-app="assets">
    <head>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
        <script src="sources/js/angular.min.js"></script>
        <script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.10/angular-route.min.js"></script>
        <script>
            var assets = angular.module('assets', ['ngRoute']);

            assets.config(function($routeProvider) {
                $routeProvider.
                when('/', {
                    templateUrl: 'home.html'
                }).
                when('/:tipusactius', {
                    templateUrl: 'tipusactius.html',
                    controller: 'TipusActiusCtrl'
                }).
                when('/:tipusactius/alta', {
                    templateUrl: 'tipusactius-alta.html',
                    controller: 'AfegirTipusActiusCtrl'
                }).
                otherwise({
                    redirectTo: '/'
                });
            });


            assets.controller('TipusActiusCtrl', function ($scope, $http){
                $http.get('http://10.0.203.73/WS/ws.php/tipusactius/').success(function(data) {
                    $scope.tipus_actius = data;
                });

                // Ordena taula per id desc
                $scope.sortField = 'idtipus_actius';
                $scope.reverse = false;
            });

            assets.controller('AfegirTipusActiusCtrl', function ($scope, $http, $sce){

                    $scope.renderHTML = "<input type='text' name='firstname'>";

                    // Camps formulari text pla
                    $scope.nomAtribut = "<input type='text' name='firstname'>";
                    $scope.tipus = "<input type='text' name='firstname'>";
                    $scope.mida = "<input type='text' name='firstname'>";
                    $scope.prioritat = "<input type='text' name='firstname'>";
                    $scope.obligatori = "<input type='text' name='firstname'>";



                    $scope.atributs = [];
                    $scope.addField = function() {
                        $scope.atributs.push($scope.atributs.length);
                };
            });

            </script>
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"

    </head>
    <body>
        <div class="container" ng-view></div>
    </body>
</html>

tipusactius-alta.html:

<script>

</script>
    <div class="row">
        <div class="col-md-8" ng-controller="AfegirTipusActiusCtrl">
            <button ng-click="addField()">Nou atribut</button>
            <div class="col-md-8">
                <table class="table">
                    <tr>
                        <td>Nom atribut</td>
                        <td>Tipus</td>
                        <td>Mida</td>
                        <td>Prioritat</td>
                        <td>Obligatori</td>
                    </tr>
                    <tr ng-repeat="atribut in atributs">
                        <td>{{nomAtribut}}</td>
                        <td>{{tipus}}</td>
                        <td>{{mida}}</td>
                        <td>{{prioritat}}</td>
                        <td>{{obligatori}}</td>
                    </tr>
                </table>
            </div>
        </div>
    </div>
</div>

我整个早上都浪费了这件事。这是没有Html渲染测试的代码。任何帮助都会有所帮助。

解决:

最后我这样做了@Ankh告诉我:

  

文本需要由Angular编译为html才能呈现   正常。尝试创建一个&#39;编译&#39;指示。这将调用$ compile   在传递给它的任何文本..

     

assets.directive(&#39; compile&#39;,compile);

function compile($compile)
{
    return {
        restrict: 'A',
        replace: true,
        link: linkFunction
    };

    function linkFunction(scope, element, attrs)
    {
        scope.$watch(
            function (scope)
            {
                return scope.$eval(attrs.compile);
            },
            function (value)
            {
                element.html(value);

                $compile(element.contents())(scope);
            }
        );
    }
} .. and in your template

<tr ng-repeat="atribut in atributs">
    <td compile="nomAtribut"></td>
    <td compile="tipus"></td>
    <td compile="mida"></td>
    <td compile="prioritat"></td>
    <td compile="obligatori"></td>
</tr>

答案 0 :(得分:2)

文本需要由Angular编译为html才能正确呈现。尝试创建一个&#39;编译&#39;指示。这会在传递给它的任何文本上调用$compile ..

assets.directive('compile', compile);

function compile($compile)
{
    return {
        restrict: 'A',
        replace: true,
        link: linkFunction
    };

    function linkFunction(scope, element, attrs)
    {
        scope.$watch(
            function (scope)
            {
                return scope.$eval(attrs.compile);
            },
            function (value)
            {
                element.html(value);

                $compile(element.contents())(scope);
            }
        );
    }
}

..并在您的模板中

<tr ng-repeat="atribut in atributs">
    <td compile="nomAtribut"></td>
    <td compile="tipus"></td>
    <td compile="mida"></td>
    <td compile="prioritat"></td>
    <td compile="obligatori"></td>
</tr>
