AngularJS ng-disabled 指令


示例

禁用/启用输入字段

禁用表单字段:<input type="checkbox" ng-model="all">
<br>
<input type="text" ng-disabled="all">
<input type="radio" ng-disabled="all">
<select ng-disabled="all">

亲自试一试 »

定义和用法

ng-disabled 指令设置表单字段(输入、选择或文本区域)的 disabled 属性。

如果 ng-disabled 属性内的表达式返回 true,则表单字段将被禁用。

ng-disabled 指令对于能够在 truefalse 之间切换值是必要的。在 HTML 中,您不能将 disabled 属性设置为 false(无论其值如何,disabled 属性的存在都会使元素禁用)。


语法

<input ng-disabled="表达式"></input>

受 <input>、<select> 和 <textarea> 元素支持。


参数值

描述
表达式 如果返回 true,则设置元素的 disabled 属性的表达式。
