最近在研究弹出层插件时发现网上很多插件功能很强大，同时插件也很庞大。在这里个人写了一个比较秀珍的弹出层插件。
jquery.popdialog.js
$(function () {$.fn.PopDialog = function (options) {var defaults = {Event: "click", //触发响应事件title: "title", //弹出层的标题type: "text", //弹出层类型(text、容器ID、URL、Iframe)content: "content", //弹出层的内容(text文本、容器ID名称、URL地址、Iframe的地址)width: 500, //弹出层的宽度height: 400, //弹出层的高度scrollTop: 200, //层滑动的高度也就是弹出层时离顶部滑动的距离isAuto: false, //是否自动弹出time: 2000, //设置自动弹出层时间，前提是isAuto=trueisClose: false, //是否自动关闭 timeOut: 2000 //设置自动关闭时间，前提是isClose=true};var options = $.extend(defaults, options);$("body").prepend("<div id='floatBoxBg'></div><div id='floatBox' class='floatBox'><div class='title'><h4></h4><span id='closeDialog'>X</span></div><div class='content'></div></div>");var $this = $(this); //当然响应事件对象var $blank = $("#floatBoxBg"); //遮罩层对象var $title = $("#floatBox .title h4"); //弹出层标题对象var $content = $("#floatBox .content"); //弹出层内容对象var $dialog = $("#floatBox"); //弹出层对象var $close = $("#closeDialog"); //关闭层按钮对象var stc, st;if ($.browser.msie && ($.browser.version == "6.0") && !$.support.style) {//判断IE6$blank.css({ height: $(document).height(), width: $(document).width() });}$close.live("click", function () {$blank.animate({ opacity: "0" }, "normal", function () { $(this).hide(); });$dialog.animate({ top: ($(document).scrollTop() - parseInt(options.height)) + "px" }, "normal", function () { $(this).hide(); });if (st) {clearTimeout(st); //清除定时器}if (stc) {clearTimeout(stc); //清除定时器}});$content.css("height", parseInt(options.height) - 70);//文本框绑定事件$this.live(options.Event, function (e) {$title.html(options.title);switch (options.type) {case "url": //当类型是地址的时候 $content.ajaxStart(function () {$(this).html("loading...");});$.get(options.content, function (html) {$content.html(html);});break;case "text": //当类型是文本的时候$content.html(options.content);break;case "id": //当类型是容器ID的时候$content.html($("#" + options.content + "").html());break;case "iframe": //当类型是Iframe的时候$content.html("<iframe src=/"" + options.content + "/" width=/"100%/" height=/"" + (parseInt(options.height) - 70) + "px" + "/" scrolling=/"auto/" frameborder=/"0/" marginheight=/"0/" marginwidth=/"0/"></iframe>");break;default: //默认情况下的时候$content.html(options.content);break;}$blank.show();$blank.animate({ opacity: "0.5" }, "normal");$dialog.css({ display: "block", left: (($(document).width()) / 2 - (parseInt(options.width) / 2)) + "px", top: ($(document).scrollTop() - parseInt(options.height)) + "px", width: options.width, height: options.height });$dialog.animate({ top: options.scrollTop + "px" }, "normal");if (options.isClose) {stc = setTimeout(function () {$close.trigger("click");clearTimeout(stc);}, options.timeOut);}});if (options.isAuto) {st = setTimeout(function () {$this.trigger(options.Event);clearTimeout(st);}, options.time);}}}); 配套的css：
*{padding: 0;margin: 0;}#floatBoxBg{display: none;width: 100%;height: 100%;background: #000;position: fixed !important; /*ie7 ff*/position: absolute;top: 0;left: 0;filter: alpha(opacity=0);opacity: 0;}.floatBox{border: #9CC95F 5px solid;position: fixed !important; /*ie7 ff*/position: absolute;top: 50px;left: 40%;background: #fff;display: none;}.floatBox .title{height: 23px;padding: 7px 10px 0;color: #fff;background-attachment: scroll;background: #9CC95F;background-repeat: repeat-x;background-position: 0px 0px;}.floatBox .title h4{float: left;padding: 0;margin: 0;font-size: 14px;line-height: 16px;}.floatBox .title span{float: right;cursor: pointer;}.floatBox .content{padding: 20px 15px;background: #fff;overflow-x: hidden;overflow-y: auto;}#closeDialog{font-size: 20px;font-weight: bold;color: #000;margin-top: -5px;}#closeDialog:hover{font-size: 20px;font-weight: bold;color: #fff;margin-top: -5px;}最终的html示例：
