angularjs - OnClick单选按钮显示隐藏div Angular js

Question

我的代码是，

  <form name="myForm" ng-controller="Ctrl">
      <input type="radio" ng-model="color" value="red">  Red <br/>
      <input type="radio" ng-model="color" ng-value="specialValue"> Green <br/>
      <input type="radio" ng-model="color" value="blue"> Blue <br/>
  </form>

  <div id="reddiv">Red Selected</div>
  <div id="greendiv">Green Selected</div>
  <div id="bluediv">Blue Selected</div>

我的脚本是

function Ctrl($scope) {
    $scope.color = 'blue';
    if ($scope.color == 'blue') {
        //blue div show
    }
    else if($scope.color == 'green') {
        //green div show
    } 
    else {
        //red div show
    }
}

我需要根据单选按钮单击显示，我尝试了上面给出的一段代码，任何想法

您正在尝试直接从 Controller 更改 View 。这不是 Angular 方式。从 Controller 的 View 中拉出模型状态。例如:

<div ng-show="color == 'red'">Red Selected</div>
<div ng-show="color == 'green'">Green Selected</div>
<div ng-show="color == 'blue'">Blue Selected</div>
