<script type="text/javascript">
//email验证
$(function(){
//input标签获取焦点/失去焦点时调用方法
$(":input[name='email']").blur(function(){
//获取input的内容
var email = $(this).val();
//给定输入内容的模板（email格式模板）
var reg = /\w+[@]{1}\w+[.]\w+/;
//将input的内容放入到模板中，进行判断
if(reg.test(email)){
//格式正确：输出“用户名可用”
$(":input[name='check-email']").val("用户名可用");
//声明正确时调用的图片
image1 = "";
//将图片放入到img标签中
$("#img1").attr("src", image1);
}else{
//格式错误：输出“请填写有效的Email地址”
$(":input[name='check-email']").val("请填写有效的Email地址");

});
//name验证
$(function(){
$(":input[name='name']").blur(function(){

$("#img2").attr("src", image2);
}else{
$(":input[name='check-name']").val("输入信息错误");

});
});
//password验证-第二次
$(function(){
$(":input[name='password-two']").blur(function(){
var name1 = $(":input[name='password-one']").val();
var name2 = $(this).val();
//首先判断密码是否大于6个字符
if(name2.length > 6){
//然后判断两次密码是否一致
if(name2 == name1){
$(":input[name='check-password-two']").val("密码可用");
image4 = "";
$("#img4").attr("src", image4);
}else{
$(":input[name='check-password-two']").val("密码不可用");
