Js pop-up layer (reLoad function is included in jQuery plug-in form)

When I was working on a project, I felt that the pop-up layer was doing quite well, but there was a problem with the code structure. I used it this time and restructured it into the jQuery plug-in form, and added the reLoad function. The Code is as follows: Copy codeThe Code is as follows: (function ($ ){
$. Module = {
_ ShowCoverLayer: function () {// display the Covering Layer
This. coverLayer = $ ("# TB_overlay ");
Var height = $ (document). height () + "px ";
Var width = $ (document). width () + "px ";
If (this. coverLayer. length> 0 ){
This.coverLayer.css ({"visibility": "visible", "height": height, "width": width });
} Else {
This. coverLayer = $ ("<div id = 'tb _ overlay 'style = 'height:" + height + "; width: "+ width +" '> </div> ");
$ ("Body"). append (this. coverLayer );
}
},
_ HideCoverLayer: function () {// hide the Covering Layer
This.coverLayer.css ("visibility", "hidden ");
},
_ ShowAjaxLoad: function (imgUrl ){
This. ajaxLayer = $ ("# TB_load ");
If (this. ajaxLayer. length> 0 ){
This.ajaxLayer.css ({"visibility": "visible "});
$ ("# TB_loadContent" ).css ({"display": "block "});
} Else {
This. ajaxLayer = $ ("<div id = 'tb _ load'> <div id = 'tb _ loadcontent'> </ div> </div> ");
$ ("Body"). append (this. ajaxLayer );
}
},
_ HideAjaxLoad: function (){
This.ajaxLayer.css ("visibility", "hidden ");
$ ("# TB_loadContent" ).css ({"display": "none "});
},
ShowWin: function (opt) {// url, title, width, height, fixTop, fixLeft, imgUrl, top
This. _ showCoverLayer ();
This. imgUrl = opt. imgUrl | "/image/ajax-loader.gif ";
This. _ showAjaxLoad (this. imgUrl );
This. win = $ ("# TB_window ");
Var that = this;
If (this. win. length = 0 ){
This. win = $ ("<div id = 'tb _ window'> </div> ");
$ ("Body"). append (this. win );
This. win. append ("<div id = 'tb _ closeajaxwindow' style = 'cursor: move 'onmousedown = 'drag (this. parentNode, event); '> <span id = 'tb _ close'> X </span> <span id = 'tb _ title'> "+ opt. title + "</span> </div> <div id = 'tb _ ajaxcontent'> </div> ");
$ ("# TB_close"). click (function (){
That. hideWin ();
});
}

This. _ init (opt );

$ ("# TB_ajaxContent"). load (opt. url, function (){
That. _ hideAjaxLoad ();
That. win. slideDown ("normal ");
});
},
HideWin: function (){
Var that = this;
This. win. fadeOut ("fast", function (){
That. _ hideCoverLayer ();
});
},
_ Init: function (opt ){
$ ("# TB_title" pai.html (opt. title );
Var top = opt. top | ($ (window ). height ()-opt. height)/2 + (opt. fixTop | 0); // + $ (window ). scrollTop ();
Var left = ($ (window ). width ()-opt. width)/2 + (opt. fixLeft | 0); // + $ (window ). scrollLeft ();
This.win.css ({"height": opt. height + "px ",
"Width": opt. width + "px ",
"Top": top + "px ",
"Left": left + "px"
});
},
ReLoad: function (opt) {// load a new page
Var that = this;
This. win. fadeOut ("fast", function (){
That. _ showAjaxLoad (that. imgUrl );
That. _ init (opt );
$ ("# TB_ajaxContent"). load (opt. url, function (){
That. _ hideAjaxLoad ();
That. win. fadeIn ("normal ");
});
});
}
}
}) (JQuery );

The CSS code is as follows:Copy codeThe Code is as follows: body {background-color: # fff ;}
Html, body {height: 100% ;}
Html body {font: 12px Arial, Helvetica, sans-serif; color: #333333}
Html> body {font: 12px Arial, Helvetica, sans-serif; color: #333333}
# TB_overlay {
Position: absolute;
Top: 0;
Left: 0;
Z-index: 100;
Width: 100%;
Height: 100%;
Background-color: # CCC;
Filter: alpha (opacity = 60 );
-Moz-opacity: 0.6;
Opacity: 0.6;
}
# TB_window {
Top: 0px;
Left: 0px;
Position: fixed;
_ Position: absolute;
Background: # fff;
Z-index: 102;
Color: #000000;
Display: none;
Border: 5px solid #666;
}
# TB_caption {
Height: 25px;
Padding: 10px 30px 10px 25px;
}
# TB_closeWindow {
Height: 25px;
Padding: 10px 25px 10px 0;
Float: right;
}
# TB_closeAjaxWindow {
Padding: 5px 10px 7px 0;
Margin-bottom: 1px;
Text-align: right;
Background-color: # e8e8e8;
}
# TB_close {
Cursor: pointer;
}
# TB_title {
Float: left;
Font-weight: bold;
Margin-left: 10px;
}
# TB_ajaxContent {
Padding: 2px 15px 15px 15px;
Overflow: auto;
}
# TB_load {
Text-align: center;
Position: fixed;
Top: 50%;

# TB_loadContent {
Margin-left:-125px;
Position: absolute;
Top:-50px;
Left: 50%;
Width: 250px;
Height: 100px;
Visibility: visible;
}

In this way:Copy codeThe Code is as follows: $. module. showWin ({url: "/deposit/clear/" + depositId + "? "+ (+ New Date ),
Title: "retreat and close ",
Width: 550,
Height: 350 });

The effect is as follows:

When it is disabled, call:Copy codeThe Code is as follows: $. module. hideWin ();

The pop-up layer has several problems:
1. Because $. load () is used, only URLs of the same source can be loaded.
2. In the case of a single page, it can be well located. If it is popped up in iframe, You need to input the top value to help locate it. This problem is caused by the difference between $ (window). top () and iframe values on a single page. I do not know how to solve this problem. I am very grateful to anyone who knows about it.
