AngularJS ng-checked 指令


示例

选中一个即可选中所有

<body ng-app="">
<p>我的汽车:</p>
<input type="checkbox" ng-model="all"> 全选<br><br>

<input type="checkbox" ng-checked="all">沃尔沃<br>
<input type="checkbox" ng-checked="all">福特<br>
<input type="checkbox" ng-checked="all">梅赛德斯
</body>
亲自试一试 »

定义和用法

ng-checked 指令设置复选框或单选按钮的 checked 属性。

如果 ng-checked 属性内的表达式返回 true,则复选框或单选按钮将被选中。

ng-checked 指令对于能够在 truefalse 之间切换值是必要的。在 HTML 中,您无法将 checked 属性设置为 false(无论其值如何,checked 属性的存在都会使元素被选中)。


语法

<input type="checkbox|radio" ng-checked="表达式"></input>

受类型为复选框或单选按钮的 <input> 元素支持。


参数值

描述
表达式 如果返回 true,则将设置元素 checked 属性的表达式。
