基于zepto的验证插件的开发

最近在做移动手机端的时候，看了很多验证插件都是基于jquery写的，但是容量和体积太大，考虑手机端对于2g和访问速度的要求，于是自己写了一个，欢迎大神们拍砖。

首先要引用 zepto;

if (typeof Zepto === 'undefined') {
    throw new Error('Zepto.Validate\'s JavaScript requires Zepto')
}

+(function ($) {
    $.fn.ValidateForm = function (options) {
        this.each(function () {
            new validateForm(this);
        });
    };
    var validateForm = function (elem) {
        this.elem = elem;
        this.opt = {
            //提示信息
            tips_required: '不能为空',
            tips_email: '邮箱地址格式有误',
            tips_num: '请填写数字',
            tips_chinese: '请填写中文',
            tips_mobile: '手机号码格式有误',
            tips_idcard: '身份证号码格式有误',
            tips_pwdequal: '两次密码不一致',
            tips_ajax: '信息已经存在',
            tips_numletter: '请输入数字和字母的组合字符',
            tips_length: '',
            tips_passport: '护照格式有误',

            //正则
            reg_email: /^\w+\@[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$/i,  //验证邮箱
            reg_num: /^\d+$/,                                  //验证数字
            reg_chinese: /^[\u4E00-\u9FA5]+$/,                 //验证中文
            reg_mobile: /^1[34578]{1}[0-9]{9}$/,                //验证手机
            reg_idcard: /^\d{14}\d{3}?\w$/,                    //验证身份证
            reg_numletter: /[^\d|chun]/,                       //验证数字和字母
            reg_passport: /^1[45][0-9]{7}|G[0-9]{8}|P[0-9]{7}|S[0-9]{7,8}|D[0-9]+$/ //验证护照
        };
        this.options = $.extend(this.opt);
        this.validate();
    };
    validateForm.prototype = {

            _this = this;
