Method One, custom pop-up layer

Pop-up layer, we commonly used, here to share a person's pop-up layer plugin, page scrolling, pop-up layer used to center in the middle of the window position.
If the HTML code is as follows

  code is as follows copy code
  <! DOCTYPE html>
            < Meta charset= "Utf-8"
    <title> pop-up layer </title>
        <body>
    <div class= "btns" > I dot </div>
     <div id= "screen" ></div>
    <div class= "PopBox"
    <em> close </em>
    Here's what you want to show, skip ...
    </div>
    </body>
    /tr>

Mainly a total of 2 layers, the outside screen is a page mask layer, used to cover the contents of the original page, can not be used.
Here's a definition of CSS.

The code is as follows Copy Code
*{
margin:0;
padding:0;
}

#screen {
width:100%;
height:100%;
Position:absolute;
top:0;
left:0;
Display:none;
z-index:9998;
Background: #666;
opacity:0.5;
Filter:alpha (OPACITY=50);
-moz-opacity:0.5;
}

. popbox{
width:600px;
Background: #fff;
border:2px #8FA4F5 Solid;
padding:1px;
Position:absolute;
top:0;
left:0;
Display:none;
z-index:9999;
}

. PopBox em{
PADDING:2PX 5px;
Position:absolute;
right:10px;
top:10px;
Background: #333;
Color: #fff;
}

The last is JS, which is a plugin in the jquery framework, so remember to introduce the jquery library file.

The code is as follows Copy Code
<script type= "Text/javascript" >
Use.
$ (function () {
$ ('. PopBox em '). Click (function () {
$ ('. PopBox '). fadeout (function () {$ (' #screen '). Hide ();});
return false;
});
$ ('. Btns '). Click (function () {
var h = $ (document). Height ();
$ (' #screen '). css ({' Height ': h});
$ (' #screen '). Show ();
$ ('. PopBox '). Center ();
$ ('. PopBox '). FadeIn ();
return false;
});
});

The following is a centered plug-in.
JQuery.fn.center = function (loaded) {
var obj = this;
Body_width = parseint ($ (window). width ());
Body_height = parseint ($ (window). Height ());
Block_width = parseint (Obj.width ());
Block_height = parseint (Obj.height ());
Left_position = parseint (BODY_WIDTH/2)-(BLOCK_WIDTH/2) + $ (window). scrollleft ());
if (body_width<block_width) {left_position = 0 + $ (window). scrollleft ();
Top_position = parseint (BODY_HEIGHT/2)-(BLOCK_HEIGHT/2) + $ (window). scrolltop ());
if (body_height<block_height) {top_position = 0 + $ (window). scrolltop ();
if (!loaded) {
Obj.css ({' position ': ' absolute '});
Obj.css ({' Top ': top_position, ' Left ': left_position});
$ (window). Bind (' Resize ', function () {
Obj.center (!loaded);
});
$ (window). bind (' scroll ', function () {
Obj.center (!loaded);
});
} else {
Obj.stop ();
Obj.css ({' position ': ' absolute '});
Obj.animate ({' Top ': top_position}, ' linear ');
}
}
</script>
