jQuery Validate验证方法及教程

//实名认证 验证
$(function(){

//中文姓名验证
jQuery.validator.addMethod("zh_verify", function(value, element) {
var tel = /^[\u4E00-\u9FA5\uf900-\ufa2d]{2,10}$/;
return this.optional(element) || (tel.test(value));
}, "请输入2~10个字的中文！");

//身份证号验证
jQuery.validator.addMethod("idcard_verify", function(value, element) {
var idcard = /^(\d{15}$|^\d{18}$|^\d{17}(\d|X|x))$/;
return this.optional(element) || (idcard.test(value));
}, "请输入正确格式的身份证号！");

//jquery.validate插件验证
$("#nameauth").validate({
errorElement: 'div',
errorClass: 'help-block',
focusInvalid: false,
ignore: "",
rules: {
tname: {
required: true,
zh_verify:true
},
idcard: {
required: true,
idcard_verify:true
},
con_idcard: {
required: true,
equalTo: '.idcard'
}
},
messages: {
tname: {
required: "真实姓名不能为空！",
rangelength: "请输入2~18个中文！"
},
idcard: {
required: "身份证不能为空！",
rangelength: "请输入15~18个字符的身份证！"
},
con_idcard: {
required: "确认证号不能为空！",
equalTo: '确认证号与身份证号不一致！'
}
},
errorLabelContainer: "#resultMsg",
submitHandler:function() {
//$(form).ajaxSubmit();    //同步提交FORM
var tname = $('input[name=tname]').val();
var idcard = $('input[name=idcard]').val();
var resultMsg = $('#resultMsg');
ajaxSubmitForm(tname, idcard, resultMsg);
}
});
})

//异步执行方法
function ajaxSubmitForm(tname, idcard, resultMsg) {
$.ajax({
url: "/member/nameauth",
data: "tname=" + tname + "&idcard=" + idcard + "&con_idcard=" + idcard,
type: "post",
cache: false,
dataType: "json",
success: function(data, textStatus){
if(data.return){
window.location.reload();
}else{
resultMsg.css({'color': 'red'}).html(data.errmsg).show().delay(2000).hide(0);
}
}
});
}

或者

$(function(){
//jquery.validate插件自定义AJAX验证（验证账户是否存在）
$.validator.addMethod("checkUserExist",function(value,element){
var user = value;
$.ajax({
type:"POST",
async:true,
dataType:'json',
url:"/account/verifyAccount",
data:"param=" + $('input[name=newpassword]').val(),
success:function(response){
if(response){
res = response.state;
}
}
});
return res;
},"账号不存在，请仔细检查！");

//jquery.validate插件验证
$("#signupForm").validate({
rules: {
newpassword: {
required: true,
rangelength:[6,30]
}
},
messages: {
newpassword: {
required: "请输入6~30个字符的交易密码！",
rangelength: "请输入6~30个字符的交易密码！"
}
},
submitHandler:function(form) {
$(form).ajaxSubmit();
}
});
})
