如何设置div显示最顶层

这个是要点击的那个文字或是图片代码











马上应聘该职位



这个就是弹出的那层的代码：

jquery代码你可以在http://www.jtlzj.net/_skin/js/jquery.js下载
然后另外的一个thickbox_plus.js里边的代码就是：
$(document).ready(TB_launch);
// function for adding Thickbox to elements of class .thickbox
// wrapped by Christian Montoya for uses other than $(document).ready
function TB_launch() {
$("a.thickbox").click(function(){
var t = this.title;
TB_show(t,this.href);
this.blur();
return false;
});
}
function TB_show(caption, url) { //function called when the user clicks on a thickbox link
try {
$("body")
.append("");
$("#TB_overlay").css("opacity","0.6");
$("#TB_overlay").css("filter","alpha(opacity=60)");
$("#TB_overlay").css("-moz-opacity","0.6");
$(window).resize(TB_position);
$("body").append("");
$("#TB_overlay").show();
var urlString = /.jpg|.jpeg|.png|.gif|.html|.htm/g;
var urlType = url.match(urlString);

if(urlType == '.jpg' || urlType == '.jpeg' || urlType == '.png' || urlType == '.gif'){//code to show images
var imgPreloader = new Image();
imgPreloader.onload = function(){
// Resizing large images added by Christian Montoya
var de = document.documentElement;
var x = (self.innerWidth || (de&&de.clientWidth) || document.body.clientWidth) - 50;
var y = (self.innerHeight || (de&&de.clientHeight) || document.body.clientHeight) - 80;
if(imgPreloader.width > x) {
imgPreloader.height = imgPreloader.height * (x/imgPreloader.width);
imgPreloader.width = x;
if(imgPreloader.height > y) {
imgPreloader.width = imgPreloader.width * (y/imgPreloader.height);
imgPreloader.height = y;
}
}
else if(imgPreloader.height > y) {
imgPreloader.width = imgPreloader.width * (y/imgPreloader.height);
imgPreloader.height = y;
if(imgPreloader.width > x) {
imgPreloader.height = imgPreloader.height * (x/imgPreloader.width);
imgPreloader.width = x;
}
}
// End Resizing
TB_WIDTH = imgPreloader.width + 30;
TB_HEIGHT = imgPreloader.height + 60;
$("#TB_window").append(""+ "");
$("#TB_closeWindowButton").click(TB_remove);
$("#TB_Image").click(TB_remove); // close when image clicked added by Christian Montoya
TB_position();
$("#TB_load").remove();
$("#TB_window").slideDown("normal");
}

imgPreloader.src = url;
}

if(urlType == '.htm' || urlType == '.html'){//code to show html pages

var queryString = url.replace(/^[^\?]+\??/,'');
var params = parseQuery( queryString );

TB_WIDTH = (params['width']*1) + 30;
TB_HEIGHT = (params['height']*1) + 40;
ajaxContentW = TB_WIDTH - 30;
ajaxContentH = TB_HEIGHT - 45;
$("#TB_window").append("");
$("#TB_closeWindowButton").click(TB_remove);
$("#TB_ajaxContent").load(url, function(){
TB_position();
$("#TB_load").remove();
$("#TB_window").slideDown("normal");
});
}

} catch(e) {
alert( e );
}
}
//helper functions below
function TB_remove() {
// #TB_load removal added by Christian Montoya; solves bug when overlay is closed before image loads
$("#TB_window").fadeOut("fast",function(){$('#TB_window,#TB_overlay,#TB_load').remove();});
return false;
}
function TB_position() {
var de = document.documentElement;
var w = self.innerWidth || (de&&de.clientWidth) || document.body.clientWidth;
var h = self.innerHeight || (de&&de.clientHeight) || document.body.clientHeight;

if (window.innerHeight && window.scrollMaxY) {
yScroll = window.innerHeight + window.scrollMaxY;
} else if (document.body.scrollHeight > document.body.offsetHeight){ // all but Explorer Mac
yScroll = document.body.scrollHeight;
} else { // Explorer Mac...would also work in Explorer 6 Strict, Mozilla and Safari
yScroll = document.body.offsetHeight;
}

$("#TB_window").css({width:TB_WIDTH+"px",height:TB_HEIGHT+"px",
left: ((w - TB_WIDTH)/2)+"px", top: ((h - TB_HEIGHT)/2)+"px" });
$("#TB_overlay").css("height",yScroll +"px");
}
function parseQuery ( query ) {
var Params = new Object ();
if ( ! query ) return Params; // return empty object
var Pairs = query.split(/[;&]/);
for ( var i = 0; i < Pairs.length; i++ ) {
var KeyVal = Pairs[i].split('=');
if ( ! KeyVal || KeyVal.length != 2 ) continue;
var key = unescape( KeyVal[0] );
var val = unescape( KeyVal[1] );
val = val.replace(/\+/g, ' ');
Params[key] = val;
}
return Params;
}

这样应该就是你想要的结果了
