Jquery实现弹出层效果

$(document).ready(function(){

$('.one').click(function(){ //点击a标签

$('.box').show(); 弹出层显示

});

$('span').click(function(){ //点击关闭按钮弹出层隐藏

$('.box').hide();

});

$('.box_all').easydrag();　　　　//弹出层可以拖动

});

</script>

body { font-size:12px; padding:100px; }

.box_all { float:left; padding:5px; background:#eee; position:absolute; top:30%; left:30%;}

.box { 500px; border:1px solid #4c7ebd; display:none; }

.box h1 { height:30px; line-height:30px; color:#fff; font-size:14px; background:#87b0e1; padding-left:10px; }

.box span { float:right; padding-right:10px; cursor:pointer;}

.box span a { display:block; height:30px; 30px; background:url(img/close.jpg) no-repeat; text-indent:-9999px;}

.box span a:hover { background:url(img/close_hover.jpg) no-repeat;}

.box p { padding:10px; height:400px; background:#fff; border:3px solid #eee; }
