已经在 IE8 , firefox3.0.11下面测试通过

复制代码 代码如下:

$.extend({

includePath: '',

include: function(file)

{

var files = typeof file == "string" ? [file] : file;

for (var i = 0; i < files.length; i++)

{

var name = files[i].replace(/^s|s$/g, "");

var att = name.split('.');

var ext = att[att.length - 1].toLowerCase();

var isCSS = ext == "css";

var tag = isCSS ? "link" : "script";

var attr = isCSS ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";

var link = (isCSS ? "href" : "src") + "='" + $.includePath + name + "'";

if ($(tag + "[" + link + "]").length == 0) document.write("<" + tag + attr + link + "></" + tag + ">");

}

}

});

$.include(['script/jquery.divbox.js','/css/pop_win.css']);

$(document).ready(function()

{

var IsFirstAlert = true;

var alertQueue = [];

window.alert = showAlert;

var divalert = "";

divalert += "<div id="divAlert">";

divalert += " <div>";

divalert += " <div id="">";

divalert += " <div ><h3>TITLE</h3></div>";

divalert += " <div></div>";

divalert += " </div>";

divalert += " <div>";

divalert += " <span id="spaAlertMessage"></span><br />";

divalert += " <div></div>";

divalert += " </div>";

divalert += " <p><input id='alertClose' type="button" value="确定" /><input type="reset" value="取消" /><br /><br /></p>";

divalert += " <p></p>";

divalert += " </div>";

divalert += " ";

divalert += "</div>";

$("body").append(divalert);

function showAlert(info)

{

alertQueue.push(info);

if (IsFirstAlert)

{

IsFirstAlert = false;

OpenAlert();

}

}

$("#alertClose").click(function()

{

$('#divAlert').CloseDiv()

if (alertQueue.length > 0)

{

setTimeout(OpenAlert, 150);

}

});

function OpenAlert()

{

$("#spaAlertMessage").html(alertQueue[0]);

alertQueue.splice(0, 1);

$("#divAlert").OpenDiv();

}

});
