我还如何在变量中获取tinymceeditor的文本输入?

also how can I get the text input of tinymceeditor in a variable ?

$scope.tinymceModel = 'Initial content';
        $scope.getContent = function() {
          console.log('Editor content:', $scope.tinymceModel);
        };
        $scope.setContent = function() {
          $scope.tinymceModel = 'Time: ' + (new Date());
        };
        $scope.tinymceOptions = {
          selector: 'textarea',
          //plugins: 'link image code',
          toolbar: ' bold italic | undo redo | alignleft aligncenter alignright | code'
        };

HTML是..

<div class="form-group">
     <textarea ui-tinymce="tinymceOptions" id="jander" ng-model="tinymceModel" placeholder="Ask your question" class="form-control"></textarea>
 </div>

推荐答案

以下是带有小提琴的示例代码

Here is a sample code with a fiddle attached

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

myApp.controller('MyCtrl', function($scope) {

  $scope.shelf = [{
    'name': 'Banana',
    'value': '$2'
  }, {
    'name': 'Apple',
    'value': '$8'
  }, {
    'name': 'Pineapple',
    'value': '$5'
  }, {
    'name': 'Blueberry',
    'value': '$3'
  }];

  $scope.cart = {
     'fruit': $scope.shelf[0]
  };
});

<div ng-controller="MyCtrl">
  <div>
    Fruit List:
    <select ng-model="cart.fruit" ng-options="state as state.name for state in shelf"></select>
    <br/>
    <tt>Cost & Fruit selected: {{cart.fruit}}</tt>
  </div>

</div>

在这种情况下，我的建议是尝试将所有输入选择都保留为Js对象(如此代码中的$ scope.shelf)，这就是Angular为数据的刚性和健壮处理而构建的，最终您可以加载这些服务器或json文件中的所有选项，而无需完全触摸HTML！

My advise in this scenario is try to keep all input choices as a Js Object (Like $scope.shelf in this code) cause thats what Angular is built for rigid and robust handling of the data, eventually you could just load those options from a server or json file and not having to touch your HTML at all!
