使用 Jquery 操作 html 字符串（在所见即所得编辑器的 Angular 应用程序中）

Question

我有一个所见即所得的编辑器，它使用 $scope.variable 作为 HTML.

的来源

现在我需要将 div 插入 HTML 字符串的某些部分。所以我可以以编程方式附加、前置、删除等部分所见即所得的显示内容。但我无法让操纵工作。

插入东西到dom应该很简单吧？但在此示例中没有附加任何内容：

JAVASCRIPT:

var app = angular.module("app", []);

app.controller("ctrl", function($scope) {

  $scope.obj = {};

  // html string
  $scope.obj.htmlString = ' <div class="wrapper-div">wrapper div<div class="container">container div<div class="inner-div">inner div</div></div></div>';

  // element inserted into html string ( virtual dom )
  $($scope.obj.htmlString).find('.container').prepend('<b>text inserted into container div</b>');

  // insert the elements to dom
  angular.element('.insert-here').prepend($scope.obj.htmlString);

});

HTML:

<body ng-app="app" ng-controller="ctrl">
  {{ obj.htmlString }}
  <div class="insert-here">
  </div>
</body>

Answer 1

您需要使用 .container 选择器并从 DOM

中获取 html

var htmlString = ' <div class="wrapper-div">wrapper div<div class="container">container div<div class="inner-div">inner div</div></div></div>';
// element inserted into html string ( virtual dom )
var $html = $('<div>' + htmlString + '</div>').find('.container').prepend('<b>text inserted into container div</b>');
htmlString = $html.html();
alert(htmlString);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

您可以使用模块ngSanitize to get the directive ngBindHtml to accomplish this. You should not have to manipulate the DOM directly when using Angular. Check out “Thinking in AngularJS” if I have a jQuery background?

var app = angular.module("app", ['ngSanitize']);
app.controller("ctrl", function($scope) {
    $scope.insertHere = "<b>text inserted into container div</b>"
}); 
<div class="insert-here" ng-bind-html="insertHere"></div>

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

app.controller("ctrl", function($scope) {
  $scope.insertHere = "<b>text inserted into container div</b>"
});

/* Styles go here */

.insert-here{
  border: 2px solid red;
  padding: 10px;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular-sanitize.min.js"></script>

<body ng-app="app" ng-controller="ctrl">
  {{ obj.htmlString }}

  <div class="wrapper-div">wrapper div
    <div class="container">container div
      <div class="inner-div">inner div</div>
    </div>
  </div>
  <div class="insert-here" ng-bind-html="insertHere">
  </div>
</body>
