我想做一个文件编辑器。通过以下代码 ( JSBin )，我们在左侧列出了所有文件名，在右侧列出了它们的主体。我用来ui-codemirror设置文件正文的样式。

但是，当我们单击文件名并从一个文件名切换到另一个文件名时，有时会看到从 textarea 到 codemirror 框架的快速滑动，这对于编辑器来说不是一个好的体验。

有没有人有解决方案来避免轻弹？angularJS另外，用and制作编辑器是一个好的方向ui-codemirror吗？

每次点击链接，都是新建编辑器，是开销操作。

The best approach is to create one editor and load the content on every click.

所以我删除了 ui-router 链接（ui-sref）和相关控制器

<script>
 var app = angular.module('flapperNews', ['ui', 'ui.router']);

  app.controller('MainCtrl', ['$scope', '$state', function ($scope, $state) {
   $scope.files = [
    { name: "index.html", body: "<html><body>index.html</body></html>" },
    { name: "index.js", body: "the body of index.js" },
    { name: "test.html", body: "the body of test.html" }];

   $scope.editorOptionsHTML = { mode: 'text/html', lineNumbers: true, matchBrackets: true };


  // for every click event it will load the content
   $scope.go=function(file){
     $scope.file=file;
   }
  }]);

和身体

<body ng-controller="MainCtrl">
  <div class="row">
    <div class="col-sm-3 col-md-3 col-xl-3 col-lg-3">
      <div ng-repeat="file in files track by $index">
        <a ng-click="go(file)">{{file.name}}</a>
      </div>
    </div>
    <div class="col-sm-9 col-md-9 col-xl-9 col-lg-9">
      <textarea ui-codemirror="editorOptionsHTML" ng-model="file.body"></textarea>
    </div>
  </div>
</body>

示例：JSBin

hide你可以通过添加类来避免轻弹，textarea就像下面的代码（jsbin）

template: '<textarea class="hide" ui-codemirror="editorOptionsHTML" ng-model="file.body"></textarea>',
