在一个网上看到的:copyurl('this_url');//内容页复制网址
function copyurl(id){
        var testCode=$("#"+id)[0].value;
if(copy2Clipboard(testCode)!=false){
$("#"+id).select();
alert("已复制，使用Ctrl+V粘贴出来发给你的朋友吧`");
        }
}
copy2Clipboard=function(txt){
        if(window.clipboardData){
                window.clipboardData.clearData();
                window.clipboardData.setData("Text",txt);
        }else if(navigator.userAgent.indexOf("Opera")!=-1){
                window.location=txt;
        }else if(window.netscape){
                try{
                        netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
                }catch(e){
                                alert("您的firefox安全限制限制您进行剪贴板操作，请打开'about:config'将signed.applets.codebase_principal_support'设置为true'之后重试。");
                                return false;
                        }
                        var clip=Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
