怎么实现检验两次密码输入不一样

Question

Answer 1

感觉你的方法有点麻烦, 下面是我前几天刚做的:
HTML部分

JS部分:
let loginpwdId = document.querySelector("#loginpwdId");//密码框
let reloginpwdId = document.querySelector("#reloginpwdId");//密码确认框
let pwdwarn = document.querySelector("#pwdwarn");//密码确认框警告
function pwd(){
let boo = loginpwdId.value == reloginpwdId.value;//两次密码比较
if(boo){//密码一致
pwdwarn.style.display = "none";//不显示警告
}else {//密码不一致
pwdwarn.style.display = "inline";//显示警告
}
}
reloginpwdId.onchange = pwd;//确认密码值改变时检验密码
