Easy Multiple Copy to Clipboard by ZeroClipboard
要实现在多个复制按钮复制的功能(具体代码在附件中，路径修改一下就行了)：

下载压缩包，得到两个“ZeroClipboard.js”和“ZeroClipboard.swf”两个文件。
首先页面中载入ZeroClipboard.js
ZeroClipboard.setMoviePath( “ZeroClipboard.swf路径” );来指定ZeroClipboard.swf的地址。
demo:
<!DOCTYPE html><html><head><meta charset="utf-8" /><title>ZeroClipboard demo实例</title><script src="../js/ZeroClipboard.js"></script><script src="../js/jquery.min.js"></script> <script>$(function(){var clip = new ZeroClipboard( document.getElementById("copy-button"), { //指定ZeroClipboard.swf的路径 moviePath: "../js/ZeroClipboard.swf" } );clip.on( 'load', function(client) { // alert( "movie is loaded" );} );clip.on( 'complete', function(client, args) { //this.style.display = 'none'; // "this" is the element that was clicked alert("复制成功，复制的内容为: " + args.text );} );clip.on( 'mouseover', function(client) { // alert("mouse over");} );clip.on( 'mouseout', function(client) { // alert("mouse out");} );clip.on( 'mousedown', function(client) {//在这里为剪贴板赋值clip.setText($("#_input").val());} );clip.on( 'mouseup', function(client) { // alert("mouse up");} );}); </script></head><body> <button id="copy-button" title="复制到剪贴板">复制到剪贴板</button> <input type="text" id="_input"></body></html>
不过在IE8下面好像有点问题，试了一下官网的例子，同样有问题，估计后面的版本会修复
