jquery 弹出层插件

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=true
            isClose: 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;
}
