jS——验证

我发现了一个现象：在原生js里的input 的onblur事件里如果直接调用方法名，则要求该方法在定义的时候的格式一定要与平时不同（name=function(){}），否则就会出现方法找不到的现象。

window.onload = function () {
    //验证用户名（只是验证长度不小于2个字符）
    UserNameValid = function (obj, className, errMessage) {
        var tip = document.getElementsByClassName(className)[0];
        var userName = obj.value;

        if (userName.length < 2) {
            tip.innerText = errMessage;
            return false;
        }
        else {
            tip.innerText = "";
            return true;
        }
    }

    ///验证昵称（多种格式匹配要求，需要时自己百度即可）
    NickNameValid = function (obj, className, errMessage) {
        var tip = document.getElementsByClassName(className)[0];
        var nickName = obj.value;
        //以数字字母（大小写）汉字开头的3到15个字符
        var match = /^[a-zA-Z0-9\u4E00-\u9FA5]{3,15}$/;
        if (nickName.length < 1 || !match.test(nickName)) {
            tip.innerText = errMessage;
            return false;
        }
        else {
            tip.innerText = "";
            return true;
        }
    }

    ///验证密码
    PwdValid = function (obj, className, errMessage) {
        var tip = document.getElementsByClassName(className)[0];
        var pwd = obj.value;
        //最少6位，包括至少1个大写字母，1个小写字母，1个数字，1个特殊字符
        var match = /^.*(?=.{6,})(?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?=.*[.!@#$%^&*? ]).*$/;
        if (pwd.length < 1 || !match.test(pwd)) {
            tip.innerText = errMessage;
            return false;
        }
        else {
            tip.innerText = "";
            return true;
        }
    }

    ///验证确认密码
    RePwdValid = function (obj, oldId, className, errMessage) {
        var tip = document.getElementsByClassName(className)[0];
        //原密码
        var oldPwd = document.getElementById(oldId).value;
        var confirmPwd = obj.value;

        if (confirmPwd.length < 1 || confirmPwd != oldPwd) {
            tip.innerText = errMessage;
            return false;
        }
        else {
            tip.innerText = "";
            return true;
        }
    }

    ///验证手机
    MobileValid = function (obj, className, errMessage) {
        var tip = document.getElementsByClassName(className)[0];
