基於zepto的驗證插件的開發

最近在作移動手機端的時候，看了不少驗證插件都是基於jquery寫的，可是容量和體積太大，考慮手機端對於2g和訪問速度的要求，因而本身寫了一個，歡迎大神們拍磚。

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: '不能爲空',
            tips_email: '郵箱地址格式有誤',
            tips_num: '請填寫數字',
            tips_chinese: '請填寫中文',
            tips_mobile: '手機號碼格式有誤',
            tips_idcard: '身份證號碼格式有誤',
            tips_pwdequal: '兩次密碼不一致',
            tips_ajax: '信息已經存在',
            tips_numletter: '請輸入數字和字母的組合字符',
            tips_length: '',
            tips_passport: '護照格式有誤',

            //正則
            reg_email: /^\w+\@[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$/i,  //驗證郵箱

            reg_chinese: /^[\u4E00-\u9FA5]+$/,                 //驗證中文
            reg_mobile: /^1[34578]{1}[0-9]{9}$/,                //驗證手機
            reg_idcard: /^\d{14}\d{3}?\w$/,                    //驗證身份證
            reg_numletter: /[^\d|chun]/,                       //驗證數字和字母
            reg_passport: /^1[45][0-9]{7}|G[0-9]{8}|P[0-9]{7}|S[0-9]{7,8}|D[0-9]+$/ //驗證護照
