在 AngularJS 中的 ng-repeat 循环中绑定 ng-model - Binding ng-model inside ng-repeat loop in AngularJS

问题：

I'm trying to deal with the issue of scope inside of an ng-repeat loop - I've browsed quite a few questions but have not quite been able to get my code to work.我正在尝试处理 ng-repeat 循环内的范围问题 - 我浏览了很多问题，但还没有完全能够让我的代码工作。

Controller code:控制器代码：

function Ctrl($scope) {
  $scope.lines = [{text: 'res1'}, {text:'res2'}];
}

View:看法：

<div ng-app>
     <div ng-controller="Ctrl">
       <div ng-repeat="line in lines">
           <div class="preview">{{text}}{{$index}}</div>

       </div>
       <div ng-repeat="line in lines">
           <-- typing here should auto update it's preview above -->
           <input value="{{line.text}}" ng-model="text{{$index}}"/>
            <!-- many other fields here that will also affect the preview -->
       </div>
     </div>
    </div>

Here's a fiddle: http://jsfiddle.net/cyberwombat/zqTah/这是一个小提琴： http : //jsfiddle.net/cyberwombat/zqTah/

Basically I have an object (it's a flyer generator) which contains multiple lines of text.基本上我有一个包含多行文本的对象（它是一个传单生成器）。 Each line of text can be tweaked by the user (text, font, size, color, etc) and I want to create a preview for it.用户可以调整每一行文本（文本、字体、大小、颜色等），我想为它创建一个预览。 The example above only shows the input field to enter text and I would like that to automatically/as-you-type update the preview div but there will be many more controls.上面的例子只显示了输入文本的输入字段，我希望它自动/按你输入更新预览 div，但会有更多的控件。

I am also not sure I got the code right for the looping index - is that the best way to create a ng-model name inside the loop?我也不确定我的代码是否适合循环索引 - 这是在循环内创建 ng-model 名称的最佳方法吗？
