难度与NG模型，NG-重复，和投入 [英] Difficulty with ng-model, ng-repeat, and inputs
问题描述
我想允许用户通过使用 ngRepeat 和 ngModel 编辑项的列表。 （看到这个小提琴）。然而，这两种方法我试过导致怪异的行为：一不更新模型，以及其他模糊每个KEYDOWN形式
I am trying to allow the user to edit a list of items by using ngRepeat and ngModel. (See this fiddle.) However, both approaches I've tried lead to bizarre behavior: one doesn't update the model, and the other blurs the form on each keydown.
我是不是做错了什么吗？这是不支持的用例？
Am I doing something wrong here? Is this not a supported use case?
下面是小提琴的code，复制方便：
Here is the code from the fiddle, copied for convenience:
<html ng-app>
<head>
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.2.1/css/bootstrap-combined.min.css" rel="stylesheet">
</head>
<body ng-init="names = ['Sam', 'Harry', 'Sally']">
<h1>Fun with Fields and ngModel</h1>
<p>names: {{names}}</p>
<h3>Binding to each element directly:</h3>
<div ng-repeat="name in names">
Value: {{name}}
<input ng-model="name">
</div>
<p class="muted">The binding does not appear to be working: the value in the model is not changed.</p>
<h3>Indexing into the array:</h3>
<div ng-repeat="name in names">
Value: {{names[$index]}}
<input ng-model="names[$index]">
</div>
<p class="muted">Type one character, and the input field loses focus. However, the binding appears to be working correctly.</p>
</body>
</html>
推荐答案
这似乎是一个具有约束力的问题。
This seems to be a binding issue.
的建议是不会绑定到元的。
您 ngRepeat 是遍历集合，里面的字符串时，它应该是在对象迭代。要解决你的问题。
Your ngRepeat is iterating over strings inside a collection, when it should be iterating over objects. To fix your problem
<body ng-init="models = [{name:'Sam'},{name:'Harry'},{name:'Sally'}]">
<h1>Fun with Fields and ngModel</h1>
<p>names: {{models}}</p>
<h3>Binding to each element directly:</h3>
<div ng-repeat="model in models">
Value: {{model.name}}
<input ng-model="model.name">
</div>
