对于非ie浏览器他是用flash来实现的，js代码如下：

复制代码 代码如下:

<script type="text/javascript">

function copy_code(copyText)

{

if (window.clipboardData)

{

window.clipboardData.setData("Text", copyText)

}

else

{

var flashcopier = 'flashcopier';

if(!document.getElementById(flashcopier))

{

var divholder = document.createElement('div');

divholder.id = flashcopier;

document.body.appendChild(divholder);

}

document.getElementById(flashcopier).innerHTML = '';

var divinfo = '<embed src="../js/_clipboard.swf" FlashVars="clipboard='+encodeURIComponent(copyText)+'" width="0" height="0" type="application/x-shockwave-flash"></embed>';

document.getElementById(flashcopier).innerHTML = divinfo;

}

alert('copy成功！');

}

</script>

<input id="inputTest" type="button" value="测试" />
