问题原因：ZeroClipboard需要再页面初始化的时候加载。
错误案例：
<div id="content">sdfdsfdsfdsfdf</div>
<a id="fuzhi" onclick="copyFun()">复制</a>
<script type="text/javascript" src="js/ZeroClipboard.js"></script>
<script type="text/javascript">
var clip = null;
function copyFun() {
clip = new ZeroClipboard.Client();
clip.setHandCursor(true);
clip.setText($("#content").val());
clip.glue("fuzhi");
clip.addEventListener("complete", function(){
alert("代码已复制到剪贴板！");
});
}
</script>
正确案例：
<div id="content">sdfdsfdsfdsfdf</div>
<a id="fuzhi" >复制</a>
<script type="text/javascript" src="js/ZeroClipboard.js"></script>
<script type="text/javascript">
var clip = null;
$(document).ready(function(){
clip = new ZeroClipboard.Client();
clip.setHandCursor(true);
clip.setText($("#content").val());
clip.glue("fuzhi");
clip.addEventListener("complete", function(){
alert("代码已复制到剪贴板！");
});
});
</script>
