AngularJS基础 ng-keyup 指令简单示例

AngularJS ng-keyup 指令

AngularJS 实例

按键松开时执行的代码:

{{count}}

该实例在输入框每次按键松开时，计算变量 "count" 会自动加 1。

定义和用法

ng-keyup 指令用于告诉 AngularJS 在指定 HTML 元素上按键松开时需要的操作。

ng-keyup 指令不会覆盖元素的原生 onkeyup 事件, 事件触发时，ng-keyup 表达式与原生的 onkeyup 事件将都会执行。

按键敲击的事件顺序:

1.Keydown

2.Keypress

3.Keyup

语法

, , , 和其他可编辑元素支持该指令。<br /> </p> <p><strong>参数值</strong></p> <p> <table style="height: 53px; width: 564px"> <tbody> <tr> <th>值</th> <th>描述</th> </tr> <tr> <td>expression</td> <td>按键松开执行的表达式。</td> </tr>
