AngularJS ng-repeat body 不替换 md-button ng-click 属性中的 $index

AngularJS ng-repeat body does not substitute $index in md-button ng-click attribute

我定义了以下模板:

<div ng-app="WebApp" ng-controller="PortfolioCtrl" ng-cloak layout="row" layout-align="center center" style="margin-top: 10px">
 <md-content layout="row" layout-wrap style="width: 580px">
  <div flex-xs flex-gt-xs="50" layout="row" ng-repeat="property in portfolio track by property.uuid">
   <md-card md-theme="default" md-theme-watch="" style="width: 280px">
    <md-card-title>
     <md-card-title-text>
      <span class="md-headline">{{property.yield}}%</span>
      <span class="md-subhead">{{property.address[0]}}</span>
      <span ng-if="property.address.length > 1" class="md-subhead">{{property.address[1]}}</span>
      <span ng-if="property.address.length > 2" class="md-subhead">{{property.address[2]}}</span>
     </md-card-title-text>
     <md-card-title-media>
     <!-- 
      <div ng-if="property.photos.length > 0" class="md-media-sm card-media">
       <img src="{{property.photos[0]}}" style="width: 75px; height: 85px" />
      </div>
      -->
     </md-card-title-media>
    </md-card-title>
    <div style="display: none">{{$index}}</div>
    <div id="property_$index" style="display: none">{{property.uuid}}</div>
    <md-card-actions layout="row" layout-align="end center">
     <md-button class="md-primary" ng-click="viewProperty( $index )">VIEW</md-button>
     <md-button class="md-primary" ng-click="uploadPhoto( $index )">UPLOAD PHOTOS</md-button>
    </md-card-actions>
   </md-card>
  </div>
 </md-content>
</div>

查看下面的浏览器开发人员输出,$index 规范在标记中正确替换:

<div style="display: none">{{$index}}</div>

但是在按钮的 ng-click 属性中和这个 DIV id:

<div id="property_$index" style="display: none">{{property.uuid}}</div>

,他们没有替代。如果我用 {{ 和 }} 包围这些 $index 规范,我会得到一个 angular 语法错误:

$index 跟踪也不起作用。请问是什么问题?

我不恰当地使用了 {{}}。在ng-click()中不用,但在其他地方,比如标签属性,需要用到。

正确使用:

<md-card md-theme="default" md-theme-watch="" flex-direction="column" ng-click="viewProperty( $index )" style="width: 158px">

并且:

<div id="property_{{$index}}" style="display: none">{{property.uuid}}</div>
