AngularJS ng-blur 指令详解及简单实例

AngularJS ng-blur 指令

AngularJS 实例

当输入框失去焦点(onblur)时执行表达式:

{{count}}

实例中 "count" 变量记录了失去焦点的次数。

运行结果：

0

实例中 "count" 变量记录了失去焦点的次数。

 定义和用法

ng-blur 指令用于告诉 AngularJS HTML 元素在失去焦点时需要执行的表达式。
AngularJS 中的 ng-blur 指令不会覆盖原生的 onblur 事件， 如果触发该事件，ng-blur 表达式与原生的 onblur 事件都会执行。
