JS复制内容到剪切板的实例代码(兼容IE与火狐)

复制代码 代码如下:

<mce:script type="text/javascript"><!--
function copyToClipboard(meintext)
{
    //ie
    if (window.clipboardData){
        window.clipboardData.setData("Text", meintext);
    }
    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=meintext;
        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("已复制本页链接,您可以使用Ctrl+V粘贴后,发送给好友!");
    return false;
}
// --></mce:script>

调用copyToClipboard(meintext);
meintext为传入参数。
<input id='a' name='a' type='text'value='good' />
<input name="" type="button" value='复制' onClick="copyToClipboard(a.value)">
