AngularJS基础 ng-focus 指令简单示例

AngularJS ng-focus 指令

AngularJS 实例

当输入框获取焦点时执行表达式:

{{count}}

该实例在输入框每次获取焦点时，计算变量 "count" 会自动加 1。

该实例在输入框每次获取焦点时，计算变量 "count" 会自动加 1。

定义和用法

ng-focus 指令用于告诉 AngularJS 在 HTML 元素获取焦点时需要执行的操作。

ng-focus 指令不会覆盖元素的原始 onfocus 事件, 事件触发时，ng-focus 表达式与原始的 onfocus 事件将都会执行。

语法

, , , , 和 window 对象都支持该指令。<br /> </p> <p>参数值</p> <p> <table style="height: 53px; width: 442px"> <tbody> <tr> <th>值</th> <th>描述</th> </tr> <tr> <td>expression</td> <td>元素获取焦点时执行的表达式。</td> </tr> </tbody> </table> </p> <p>以上就是对Angular ng-focus 的基础资料整理，后续继续补充。</p></div> </div> <div style="clear: both;"></div> <div class="author-info fl"> <div><span class="gray">转载请注明：</span>文章转载自 <a
