Use jQuery's easydrag plug-in to implement a draggable DIV pop-up box_jquery

EasyDrag is a jQuery plug-in for dragging page elements.

Before encountering the easydrag plug-in, it was not easy to implement a pop-up box!

It is often said that nothing comes for free, but this is not the case in the world of coding. More open source frameworks benefit us, but also poison us!

Stop talking nonsense and see the effect first:

All codes: 

<!DOCTYPE HTML> 
<html> 
<head> 
<title>easydrag实现可拖动的DIV弹出框</title> 
<style> 
/* 重置浏览器默认样式 */ 
body,h1,h2,h3,h4,h5,h6,p,ul,ol,li,form,img,dl,dt,dd,table,th,td,blockquote,fieldset,div,strong,label,em{margin:0;padding:0;border:0;} 
ul,ol,li{list-style:none;} 
input,button{margin:0;font-size:12px;vertical-align:middle;} 
body{font-size:12px;font-family:Arial, Helvetica, sans-serif; color:#333; margin:0 auto; } 
table{border-collapse:collapse;border-spacing:0;} 
a{ color:#333; text-decoration:none;} 
a:hover{ text-decoration:none;} 
.wrap{ width:960px; margin:20px auto;} 
.box{ display:none; background:#fff; border:1px solid #ccc; position:absolute;} 
#popbox{ width:550px;height:320px;overflow:hidden;} 
#handler{ width:98%; height:30px; line-height:30px; overflow:hidden; color:#fff; border-bottom:1px solid #ccc; background:#ccc; padding-left:2%; float:left;} 
.btn{ display:block; width:90px; height:28px; border:1px solid #ccc; line-height:28px; text-align:center; margin-right:20px; float:left; display:inline; margin-right:15px; cursor:pointer;} 
.close{ display:block; background:url(images/close.gif) no-repeat; width:13px; height:13px; float:right; text-indent:-999em; cursor:pointer; display:inline; margin:8px 12px 0 0;} 
.head i{ float:left; font-style:normal;} 
.content{ width:100%; float:left;} 
.content img{width:100%;} 
</style>

<script type="text/javascript" src="js/easydrag.js"></script> 
<script language="javascript"> 
$(function(){ 
//btn绑定click事件 
$('.btn').click(function(){ 
//设置弹出框居中 
$('#popbox').css({ 
left: ($(window).width() - $('#popbox').outerWidth())/2, 
top: ($(window).height() - $('#popbox').outerHeight())/2 + $(document).scrollTop() 
}); 
$('#popbox').easydrag(); 
//淡入已隐藏的div 
$('#popbox').fadeIn(); 
$('#popbox').setHandler('handler'); 
$('.close').click(function(){ 
//淡出效果来隐藏弹出的div 
$('#popbox').fadeOut(); 
}); 
}); 
}); 
</script> 
</head> 
<body> 
<div class="wrap"> 
<b class="btn">打开弹出框</b> 
<div id="popbox" class="box"> 
<div class="head" id="handler"><b class="close">关闭</b><i>点击标题位置进行拖动</i></div> 
<div class="content"><a href="http://blog.csdn.net/xmtblog/"><img src="images/img03.jpg" /></a></div> 
</div> 
</div> 
</body> 
</html>
