我想隐藏/显示基于复选框的 div。看起来很简单。我将复选框的值存储在模型中并在 div ng-show 中使用它。我究竟做错了什么？

<div ng-app='visibleApp'>
    <div ng-controller='myController'>
         <input type="checkbox" name="hideBasicInfo" ng-model="hideBasicInfo">hide the basic information section
         <div ng-show="{{!hideBasicInfo}}">
             <label for="firstName">First Name:</label>
             <input type="text" name="firstName" ng-model="firstName"/></br>

             <label for="middleName">Middle Name:</label>
             <input type="text" name="middleName" ng-model="middleName"/></br>
             <label for="lastName">Last Name:</label>
             <input type="text" name="lastName" ng-model="lastName"/>
         </div>
         <hr/>
         <div>
             <h4>Debug Information</h4>
             hideBasicInfo: {{hideBasicInfo}}<br/>
             !hideBasicInfo: {{!hideBasicInfo}}
         </div>
     </div>
</div>

JS文件：

var visibleApp = angular.module('visibleApp',[]);

visibleApp.controller('myController', function($scope){
     $scope.data = "my data";
     $scope.hideBasicInfo = false; 
});

谢谢你。

差不多好了...

 <div ng-hide="hideBasicInfo">
    ...
 </div>

不需要模板大括号 ( {{}} )。

Execute this code:`enter code here`
<!DOCTYPE html>
<html>
<head>
  <script src="angular.js"></script>
</head>

<body ng-app>
  <h3>1. Show</h3>
  <label>Show the square: <input type="checkbox" ng-model="mustShow" /></label><br />
  <div ng-show="mustShow" style="width: 50px; height: 50px; background-color: red;"></div><br />
  <br />
  <h3>2. Hide</h3>
  <label>Hide the square: <input type="checkbox" ng-model="mustHide" /></label><br />

<div ng-show='One'>
 <p>Section One</p>
</div>

<div ng-show='Two'>
 <p>Section Two</p>
</div>

<div ng-show='Three'>
 <p>Section Three</p>
</div>
