<html>加上上一篇拦截器文章代码综合一下
<body>
<div>
<input type="hidden" id="txtHiddenCtx" value="${pageContext.request.contextPath}" />
用户名：<input type="text" id="txtuserid"/><br>
密码：<input type="password" id="txtpassword"/>
<input type="button" value="登录" onclick="loginc();"/>
</div>
<script type="text/javascript">
var ctx = $("#txtHiddenCtx").val();
function loginc() {
var paramData = new Object();
paramData.userid = $("#txtuserid").val();
paramData.password = $("#txtpassword").val();
var jsonData = JSON.stringify(paramData);
$.ajax({
url : ctx + "/auth/loginc",
type : "POST",
async : true,
// contentType:"application/x-www-form-urlencoded",
contentType : "application/json;charset=utf-8",
dataType : "json",
data : jsonData,
beforeSend : function(XMLHttpRequest) {
},
success : function(data, textStatus) {
if(data.flag == 1){
window.location.href = ctx + "/";
}else{
alert(data.msg);
}
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
// 通常情况下textStatus 和errorThown只有其中一个有值
alert("error: " + XMLHttpRequest.responseText);
},
complete : function(XMLHttpRequest, textStatus) {
}
});}
