##该插件是基于jquery或者zepto来实现的h5移动端分享插件
2+
3+
##h5Share实现的功能有：
4+
5+
* 在UC浏览器或者QQ浏览器实现打开手机QQ（发送好友）,微信APP朋友圈、发送好友的自定义分享。
6+
7+

9+
![image](http://7qn7ih.com1.z0.glb.clouddn.com/20160216161011.jpg)
10+
* 微信浏览器浏览器右上角提示分享箭头。

13+
14+
* 在非上面的UC、QQ浏览器，微信其他浏览器只会显示QQ空间和新浪微博的h5分享ICON。
15+
16+

17+
18+
##注意问题
19+
20+
* 在微信浏览器想实现分享，必须要在公众平台配置JS安全域名。
21+
* UC浏览器中的分享朋友圈、发送好友暂时没有发送图片的配置。（貌似没有UC没有提供接口）。
