用Jquery重写windows.alert方法实现思路

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' " : " 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 style=\"width:380px; height:180px; overflow:hidden;display:none\" id=\"divAlert\">";
divalert += " <div class=\"win_c\">";
divalert += " <div class=\"win_t\" id=\"\">";
divalert += " <div class=\"mail_timg\" ><h3>TITLE<\/h3><\/div>";
divalert += " <div class=\"clear\"><\/div>";
divalert += " <\/div>";
divalert += " <div class=\"alrt2\" style=\"text-align:center\">";
divalert += " <span id=\"spaAlertMessage\" class=\"f14 ifont\"><\/span><br \/>";
divalert += " <div class=\"clear\"><\/div>";
divalert += " <\/div>";
divalert += " <p class=\"Acenter\"><input type=\"button\" value=\"确定\" class=\"btn7\" \/>&nbsp;&nbsp;&nbsp;&nbsp;<input type=\"reset\" value=\"取消\" style=\"display:none\" class=\"btn8\" \/><br \/><br \/><\/p>";
divalert += " <p>&nbsp;<\/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();
}
});

注：以上引用js与CSS的jquery插件
