$(document).ready(function(){
var time=0;
$("#button").click(function(){
showWindow();
center("register");
$("#close").click(function(){
removeWindow();
});
});
function showWindow(){
var htm="\u00d7\u6ce8\u518c\u6846\u5b9e\u4f8b\u6ce8\u518c";
if(time==0){
$("body").append(htm);
time=1;
}
return false;
}
function removeWindow(){
$("#register").fadeOut(function(){
$("#register").remove();
});
return false;
}
function center(id){
var h=$(window).height();
var w=$(window).width();
var fh=$("#"+id).height();
var fw=$("#"+id).width();
$("#"+id).css({
"top":(h-fh)/2,
"left":(w-fw)/2
});
}
$(window).resize(function(){
center("register");
});
});
使用window.open();方法先打开一个窗口，里面可以带一些参数设置窗口的显示属性，然后使用新打开窗口的document对象的write()方法写入要显示的消息，就可以弹出可以复制文本的框了，方法跟guaimutou所说基本上一样。不过实现起来需要一些技巧，有点麻烦。试试看.
使用自写的弹出窗口就好了：（将下列代码添加到页面中，使用时调用myalert函数，例如：myalert('hello world!');）
function myalert(str)
{
var shield = document.createElement("DIV");
shield.id = "shield";
shield.style.position = "absolute";
shield.style.left = "0px";
shield.style.top = "0px";
shield.style.width = "100%";
shield.style.height = document.body.scrollHeight+"px";
//弹出对话框时的背景颜色
shield.style.background = "#fff";
shield.style.textAlign = "center";
shield.style.zIndex = "25";
//背景透明 IE有效
//shield.style.filter = "alpha(opacity=0)";
var alertFram = document.createElement("DIV");
alertFram.id="alertFram";
alertFram.style.position = "absolute";
alertFram.style.left = "50%";
alertFram.style.top = "50%";
alertFram.style.marginLeft = "-225px";
alertFram.style.marginTop = "-75px";
alertFram.style.width = "450px";
alertFram.style.height = "150px";
alertFram.style.background = "#ff0000";
alertFram.style.textAlign = "center";
alertFram.style.lineHeight = "150px";
alertFram.style.zIndex = "300";
strHtml = "<ul style=\"list-style:none;margin:0px;padding:0px;width:100%\">
";
strHtml += " <li style=\"background:#DD828D;text-align:left;padding-left:20px;font-size:14px;font-weight:bold;height:25px;line-height:25px;border:1px solid #F9CADE;\">[自定义提示]</li>
";
strHtml += " <li style=\"background:#fff;text-align:center;font-size:12px;height:120px;line-height:120px;border-left:1px solid #F9CADE;border-right:1px solid #F9CADE;\">"+str+"</li>
";
strHtml += " <li style=\"background:#FDEEF4;text-align:center;font-weight:bold;height:25px;line-height:25px; border:1px solid #F9CADE;\"><input type=\"button\" value=\"确 定\" onclick=\"doOk()\" /></li>
";
strHtml += "</ul>
";
alertFram.innerHTML = strHtml;
document.body.appendChild(alertFram);
document.body.appendChild(shield);
var ad = setInterval("doAlpha()",5);
this.doOk = function(){
alertFram.style.display = "none";
shield.style.display = "none";
}
alertFram.focus();
}
显示一个漂浮的层不就OK了吗？放上你要和用户对话的按据。OK
弹出一个没有边框的网页不就OK了吗 跟QQ登陆后出新闻的那个一样
还用alert做提示啊`
