记录一个有用的js代码，其效果是点击提交表单后动态提示信息。

可以修改返回成功部分完成页面的跳转。

function validateForm() {    return $("#form1").validate({        rules: {            userName: { required: true, maxlength: 10 },            password: { required: true, maxlength: 10 }        },        messages: {            userName: { required: "不能为空", maxlength: jQuery.format("不能超过{0}个字符") },            password: { required: "不能为空", maxlength: jQuery.format("不能超过{0}个字符") }        }    }).form();};function doSubmit() {    console.log("click!");     if (validateForm()) {        console.log("validate success!");         var usernama = $("#userName").val();        var password = $("#password").val();        console.log("username:" + usernama);        console.log("password:" + password);        var data = { 'userName': usernama, 'password': password };         $.ajax({            type: "POST",            data: JSON.stringify(data),            contentType: "application/json; charset=utf-8",            dataType: "json",            success: function (data) {                console.log(data);                 if (this.result == "OK") {                    console.log("respon success");                    //do some thing!                }                else {                    $("#loginInfor").css({ "display": "block", "opacity": "1" });                    $("#loginInfor").animate({ opacity: 0 }, 2000);                    $("#loginInfor").html("用户名密码错误");                    console.log("respon success, but the password is worry!");                }            },            error: function () {                console.log("respon error");            }        });        }};
