jQuery+ajax实现修改密码验证

<script
type="text/javascript">

    //获取url中的参数

    $(function(){

       var userName = window.location.href;

       var aa = userName.indexOf("=");

           console.log(userName);

        if (aa == -1)

           return "";

       userName=userName.substring(aa+1);

        //给hidden赋值并显示

       $("#userName").val(userName).attr("type","text");

      

       //ajax请求修改密码

       var rePassword = $("#repeatPassword").val();

       //6到15位字母或数字

       var reg=/^[0-9a-zA-Z]{6,15}$/;

       //新密码校验

       $("#newPassword").blur(function(){

           $("#msg").css("display","none");

           var newPassword = $("#newPassword").val();

           if(newPassword==""||newPassword==null){

              $("#msg").html("请输入新密码！").css("display","block");

           }elseif(!reg.test(newPassword)){

              $("#msg").html("密码格式不正确,请重新输入！").css("display","block");

           }

       });

      

       //重复密码校验

       $("#repeatPassword").blur(function(){

           var newPass = $("#newPassword").val();

           var repPass = $("#repeatPassword").val();

           if(newPass != repPass){

              $("#msg").html("两次输入密码不一致,请重输！").css("display","block");

           }

       });

      

       //表单提交前校验

       $("#updateBtn").click(function(){

           var flag =
true;

           var newPass = $("#newPassword").val();

           var repPass = $("#repeatPassword").val();

           var reg1=/^[0-9a-zA-Z]{6,15}$/;

           if(!reg1.test(newPass)||newPass!=repPass||newPass ==""||newPass==null){

              flag = false;

           }

           if(flag){

              $.ajax({

                  url:"/HuaMuWebsite/userManage/editPassword?userName="+userName,

                 type:"POST",

                 async:false,

                 data:$("#fm").serialize(),
//表单数据序列化,
可以对form表单进行序列化，从而将form表单中的所有参数传递到服务端。

                 success:function(data){

                 //json字符串转为json对象

                  var jsonObj=eval("("+data+")");

                  if(jsonObj.success !=
null){

                     alert(jsonObj.success);

                     window.location.href="/HuaMuWebsite/admin/login.html";

                  }else{

                     alert(jsonObj.failure);

                  }

              },

              error:function(e){

                  alert("请求出错！");

              }

              });

           }     

});

    });
