第一步：页面引入css：<link rel="stylesheet" type="text/css"" href="common/css/loginAjax.1.0.css"><!-- 引入封装的ajax样式 -->
css范例：
/**
* @description 页面登录弹出框样式
* @page 目前支持宇航所有页面
* @author maohuidong
* @date 2017-06-07
*/
/*登录框样式*/
.loginDiv {
position: fixed;
width: 5.8rem;
left: 50%;
top: 50%;
margin-top: -1.9rem;
margin-left: -2.9rem;
z-index: 101;
background-color: #048fbe;
border-radius: 10px;
text-align: center;
padding-top: 0.45rem;
font-size: 0.28rem;
display:none;
}
.loginDiv p{
color: #fff;
line-height: 0.45rem;
height: 0.9rem;
padding: 0 0.2rem;
}
.loginDiv p input{
height: 0.5rem;
padding: 0.1rem;
border-radius: 0.08rem;
background: #fff;
-webkit-box-shadow: 0 0 0px 1000px white inset;
}
.loginDiv p label{
display: inline-block;
width: 1.2rem;
text-align: right;
}
/*登录信息提示*/
.loginDiv .msg{
color: #fff;
line-height: 0.45rem;
height: 0.9rem;
padding: 0 0.2rem;
display:none;
}
/*登录按钮*/
.loginDiv .btn{
position: absolute;
width: 100%;
height: 0.88rem;
left: 0;
bottom: 0;
background-color: #fff;
border-radius: 0 0 10px 10px;
}
.login-dialog-mask{
top: 0%;
left: 0%;
width: 100%;
height: 100%;
background: rgba(0, 0, 0, 0.4);
z-index: 9;
position: fixed;
display: block;
}
第二步：页面引入js：<script type="text/javascript" src="common/js/loginAjax.1.0.js"></script><!-- 引入封装的ajax -->
<script type="text/javascript" src="common/js/jquery.js"></script><!-- 引入jquery库 -->
js 核心代码：
