给你说下程序执行的流程吧:
- 页面初始化时,
<a></a>
元素有onclick事件; - 第一次点击, 触发
onclick
事件, 调用setCopyClip
函数后, 绑定一个ZeroClipboard.Client
对象; - 这条是重点 : 在
new ZeroClipboard.Client
时,ZeroClipboard
会创建一个div
元素覆盖在<a></a>
元素之上; - 第二次点击, 因为ZeroClipboard创建的
div
在<a></a>
元素之上, 所以不会触发onclick
事件; - 第一次绑定的
ZeroClipboard.Client
对象触发complete
事件, 弹出复制成功!
弹窗.
PS:你用的ZeroClipboard版本很老的吧...
