Question

如果选择其中一个单选按钮，我需要显示一个div。我在想的是：

<body ng-controller="MainCtrl">
        <form name="myForm" ng-submit="submitForm()">
           <label><input type="radio" name="test" ng-model="radioValue" value="1"/> One</label>
           <label><input type="radio" name="test" ng-model="radioValue" value="2"/> Two</label>
           <label><input type="radio" name="test" ng-model="radioValue" value="3"/> Three</label>
           <div>currently selected: {{radioValue}}</div>
           <div ng-show = "{{radioValue}}=='1'">
               <p> Metric Test values</p>
               <b> Src: Value1 </b>
               <b> Metric1: Value2 </b>
               <b> Density: Value3 </b>
           </div>
           <button type="submit">Submit</button>
        </form>
  </body>

然而，无论是否选择了组合框，我都无法显示div
