兼容ie,ff 复制到剪切板js代码
<form name="form01"><input type="text" onmouseo教程ver="this.select();" class="iform sizeb" value="需要复制的内容！" name="contents"/>
<input type="button" onclick="copy_code(document.form01.contents.value);" /></form>

或直接

<input type="button" onclick="copy_code('需要复制的内容！');" />

<script type="text/网页特效" language="javascript">
        //复制到剪切板js代码
        function copyToClipBoard(s) {
            //alert(s);
            if (window.clipboardData) {
                window.clipboardData.setData("Text", s);
                alert("已经复制到剪切板！"+ "n" + s);
            } else if (navigator.userAgent.indexOf("Opera") != -1) {
                window.location = s;
            } else if (window.netscape) {
                try {
                    netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
                } catch (e) {
                    alert("被浏览器拒绝！n请在浏览器地址栏输入'about:config'并回车n然后将'signed.applets.codebase_principal_support'设置为'true'");
                }
                var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
                if (!clip)
                    return;
                var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
                if (!trans)
                    return;
                trans.addDataFlavor('text/unicode');
                var str = new Object();
                var len = new Object();
                var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
                var copytext = s;
                str.data = copytext;
                trans.setTransferData("text/unicode", str, copytext.length * 2);
                var clipid = Components.interfaces.nsIClipboard;
                if (!clip)
                    return false;
                clip.setData(trans, null, clipid.kGlobalClipboard);
                alert("已经复制到剪切板！" + "n" + s)
            }
        }</script>

对于非ie浏览器他是用flash来实现的，js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" onclick="copy_code('拷贝成功！帆船书会http://www.111cn.net')" />
