angularjs NG-NG重复的模式指令内使用$指数 [英] angularjs ng-repeat use $index inside ng-model directive

问题描述

尝试使用 NG-重复

<ul>
    <li ng-repeat = "n in [1,2,3,4]>

     <label id="{{'p'+ n }}"> {{n}} </label>
     <label ng-model="{{'p'+ n }}"> {{n}} </label>

     </li>

</ul>

第一个标签的作品。它的身份证的正确分配。但是，第二个标签不工作。

The first "label" works. Its "id" is assigned properly. But the second "label" doesn't work.

是因为NG-模式无法动态创建？

Is that because "ng-model" cannot be created dynamically?

我试图用＆LT;选择NG模型... NG选项...＆GT; A 中的NG-重复。不能够创造这些NG-模式动态，我在这里卡住了。

I was trying to use <select ng-model ... ng-options ...> within a ng-repeat. Not being able to create these "ng-model" dynamically, I am stuck here.

推荐答案

NG-模型是角属性，你并不需要包括 {{}} - 尝试 NG-模式='p'+ N

ng-model is an Angular attribute, you don't need to include the {{}} -- try ng-model="'p' + n"
