我大部分时间都在尝试解决这个脚本来做你通常认为是超级容易做的事情。
我的小提琴 http://jsfiddle.net/pistachio_labs/LWCJM/
实际库 https://github.com/sapegin/social-likes/tree/master/src
在这个脚本中，它显示了一个带有弹出 div 的共享按钮，显示了每个社交网络的总份额。
默认情况下，我有显示标题“共享”的按钮，但是当它有 0 个共享时，它只显示标题“共享”
我一直在尝试做的是弄清楚如何在按钮上的单词 share 旁边显示 0。
但无论我做什么，我都无法在“共享”一词旁边的按钮上显示一个简单的 0。
任何想法都非常感谢。
