老师好,
对着代码敲得, 每次运行结果都不一样, 不知道错哪里了, 这一次是, 用户名和密码 一直显示不合法, 邮箱验证正常,
之前是怎么都不正常的, 请老师给看看
源码:
公共部分的验证方法
function check(id, reg){
//获取元素对象
var ele = document.getElementById(id);
//获取alt值
var alt = ele.alt;
//获取value值
var val = ele.value;
//获取span对象
var span = document.getElementById(id+"_span");
//开始验证
if(val==null || val==""){
span.innerText = "×"+alt+"不能为空";
span.style.color = "red";
}else if(reg.test(val)){
span.innerText = "√"+alt+"合法";
span.style.color = "green";
}else{
span.innerText = "×"+alt+"不合法"
span.style.color = "red";
}
}真实验证的方法
/***********验证用户名****************/
function checkName(){
var reg = /^[\u4e00-\u9fa5]{3,5}$/;
check("uname", reg);
}
/************验证密码**************************/
function checkPwd(){
var reg = /^\d{3, 6}$/;
check("pwd", reg);
}
/***********验证手机号***************************/
function checkPhone(){
var reg = /^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0|1|2|3|5|6|7|8|9])\d{8}$/;
check("phone", reg);
}
/***********验证邮箱*****************************/
function checkEmail(){
var reg = /^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
check("email", reg);
