姓名：	onfocus="this.className='input220L';this.onmouseout=''" onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" onmousemove="this.className='input220Lg'" onmouseout="this.className='input220'"> *
昵称：	onfocus="this.className='input220L';this.onmouseout=''" onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" onmousemove="this.className='input220Lg'" onmouseout="this.className='input220'"> *
账号：	onfocus="this.className='input220L';this.onmouseout=''" onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" onmousemove="this.className='input220Lg'" onmouseout="this.className='input220'"> *

2、公用的带有弹出层和关闭层的两个方法

//popup layer
function isIE(num){
var num = num || "",
tester = document.createElement('div');
tester.innerHTML = '';
return !!tester.getElementsByTagName('i')[0];
}
function popupLayer(objClass,targetClass){
$("."+objClass).click(function(){
$("#spm").show();
var target=$("."+targetClass);
var targetWidth=target.outerWidth();
var targetHeight=target.outerHeight();
if(isIE(6)){
$("#spm").hide();
//$("select").hide();
var top=$(document).scrollTop()+$(window).height()/2;
target.css({"top":top+"px"});
$(window).scroll(function(){
var top=$(document).scrollTop()+$(window).height()/2;
target.css({"top":top+"px"});
});
}
target.css({"margin-top":-parseInt(targetHeight/2)+"px","margin-left":-parseInt(targetWidth/2)+"px"});
target.show();
return false;

});

}
//隐藏div的操作
function closeLayer(objClass,targetClass)
{
$("."+objClass).click(function(){
$(this).parents("."+targetClass).hide();
$("#spm").hide();

});
}

3、1中调用3中js实现效果的js代码

$(function(){
//第一个参数是按钮的class属性值，第二个是被隐藏的div属性值
popupLayer("but_tj","Popup");
closeLayer("Close","Popup");
});

//我们通过点击添加或修改按钮后使当前操作的div隐藏
//closeAdd("Popup");
function closeAdd(targetClass){
$("."+targetClass).hide();
$("#spm").hide();
}

4、css样式

html {min-height: 100%;position: relative;overflow: hidden;}
body {background-color: #FFF;font: 12px 微软雅黑, Arial, sans-serif;margin: 0;}
h1 {font-size: 12px;font-size: inherit;font-weight: normal;}
a {text-decoration: none;}
a:hover {text-decoration: none;}
.clear {overflow: hidden;clear: both;}
#right {margin-left: 190px;min-height: 100%;padding: 0;}
.right_top {height: 40px;background-color: #f5f5f5;color: #666666;border-bottom: 1px solid #e5e5e5;line-height: 40px;padding-left: 50px;position: relative;z-index: 1;}
.right_top a {color: #2b7dbc;}
.right_nav {margin: 0 30px;height: 37px;background-color: #438eb9;line-height: 37px;position: relative;margin-top: 15px;}

.Popup_top {height: 40px;line-height: 40px;border-bottom: 1px solid #cccccc;}
.Popup_top h1 {float: left;font-size: 14px;}
.Close {float: right;font-family: Arial, Helvetica, sans-serif;margin-right: 10px;margin-top: 10px;}
.Popup_cen {padding-top: 10px;width: 100%;height: 440px;overflow: auto;}

/*BD_tab*/
.BD_tab {width: 500px;margin: 0 auto;}
.BD_tab td {padding-top: 12px;}
.input220,.input220L,.input220Lg {width: 220px;height: 28px;border: 1px solid #d3d3d3;padding-left: 5px;line-height: 28px;font-family: "微软雅黑";color: #000;}
.input220L {border: 1px solid #377bcb;background-color: #d5e8ff;}
.input220Lg {border: 1px solid #7fb1eb;background-color: #d8e6f7;}
.input220 {border: 1px solid #d3d3d3;}
