jQuery验证密码重复输入问题

你写的有问题，你的验证是新密码和旧密码必须一致。equalTo : "#oldPass" 你这是要新密码和旧密码一致。

示例，对比一下，或者加下面放在你的页面看是否正常，是否受到其他因素的影响<!DOCTYPE html>

newPass : {
required : true,
minlength : 6,
maxlength : 20,
equalTo : "#renewPass "
},
renewPass : {
required : true,
equalTo : "#newPass"
}我没用过这个验证，按照你这个东西， newPass -> equalTo : "#renewPass "; renewPass ->equalTo : "#newPass"这样才是两个一致吧，你是这么改的吗

我看网上写的介绍，只需要其中一个写equalTo 就可以了，不需要两个都写

我测试了可以用

你的文本框没有设置ID,equalTo: 后面是#开始的是根据ID取值比较的。取不到值所以一值不等。

不是根据name属性吗。。#开始是根据ID选取的，这就是一个选择器，你可以加个ID和name一样试试。

确实是这个问题，我要记录下，谢谢，纠结了我半天
