jQuery实现简单弹出框效果实例
作者:zhengvipin
这篇文章主要给大家介绍了关于jQuery实现简单弹出框效果的相关资料,几天一直在研究JQuery,确实很好用,有很多需求都是要弹出框,文中通过实例代码介绍的非常详细,需要的朋友可以参考下
功能点
1、点击“更多”出现弹出框
2、点击下拉列表触发回调
3、点击空白区域收起弹出框
效果演示
PS:鼠标右键效果图`另存为`到本地 ,再将图片后缀gif改为rar即可得到完整代码压缩包。
实现思路
1、提前声明弹出标识做判断;
2、通过jQuery的has()、is()或其他类似方法判断点击的是弹出层以外的空白区域。
PS:太久不写jQuery了,很生疏了...
