注册验证是可以正常进入服务器并于controller中的checkRegister交互的，并且控制台能输出sql语句。但是登录却不行，检查很多遍没发现写错什么，但是并没有进入到checkLogin方法，连方法内部的systemout一个都没输出来。最让我不解的是，用谷歌和ie浏览器时，不进对应的方法不说，内存占用逐渐上升飙红了，网页关掉就恢复正常。而这些问题，注册页面统统没有。。我查来查去真不知道是什么原因了，请各位大神帮忙指点分析一下。下面贴上源码登录的JS：<script type="text/javascript" src="<%=path %>/statics/js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("input").blur(function(){
var ele=$(this);
var getValue=ele.val();//获取创建用户时输入的文本信息
if($(this).is("#cardId")){
var reg=/^\d{18,18}$/;
if(reg.test(getValue)==false){
flag=false;
ele.attr("style","color:red;border:1px solid red;");
ele.next().attr("style","color:red;").html(" 账号输入有误！");
}else{
ele.attr("style","color:green;border:1px solid green");
ele.next().attr("style","color:green;").html(" 账号输入正确！");
}
}else if($(this).is("#password")){
var reg=/^\w{6,}$/;
if(reg.test(getValue)==false){
ele.attr("style","color:red;border:1px solid red;");
ele.next().attr("style","color:red;").html(" 密码输入有误！");
}else{
ele.attr("style","color:green;border:1px solid green");
ele.next().attr("style","color:green;").html(" 密码输入正确！"); }
}
});
$("form").submit(function(){
alert(1);
var result=false;
var cardId=$("#cardId");
var password=$("#password");
$.ajax({
async:false,
url:"<%=path%>/users/checkLogin",
type:"post",
data:{"cardId":cardId,"password":password},
dataType:"json",
success:function(data,xstatus,xhr){
if(data==1){
alert("该账号不存在，请先注册！")
}else if(data==2){
alert("登录失败，账号密码不匹配！")
}else if(data==3){
alert("登录失败，该账号已冻结！")
}else if(data==0){
result=true;
}
},
error:function(){
alert(4);
}
});
return result;
});
});
