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！");

}

});

}

});

});

</script>
