用户名/密码/确认密码不能为空，密码需和确认密码一致，如果不符合，阻止注册操作，并将错误信息展示给用户看。
onsubmit
13.2、需求分析
13.3、案例实现
<script>
//密码和确认密码一致性校验
//前提：密码和确认密码必须填写
function checkPwdAndRepwd(f1,f2){
if(f1&&f2){
//密码和确认密码不为空，进行非空校验
//1、密码和确认密码 值拿到
var pwd=document.getElementById("password").value;
var repwd=document.getElementById("repassword").value;
var msg=document.getElementById("repasswordMsg");
var div=document.getElementById("repasswordDiv");
//2、一致性判断
if(pwd==repwd){
div.className="form-group";
msg.innerHTML="";
return true;
}else{
div.className+=" has-error";
msg.innerHTML="必须和密码一致";
return false;
}
}else{
//密码和确认密码有一个为空，直接返回false
return false;
}
}
//非空校验
function checkNotNull(nid){
//1、获取表单输入项 元素对象
var nodex=document.getElementById(nid);
//获取对应的错误信息回显 label元素
var msg=document.getElementById(nid+"Msg");
//获取对应的DIV
var div=document.getElementById(nid+"Div");
//2、对进行非空判断
var reg = /^s*$/;//如果有0~多个空白符，就为true
if(reg.test(nodex.value)){
//信息不合格
div.className+=" has-error";
msg.innerHTML="不能为空";
return false;
}else{
//信息合格
div.className="form-group";
msg.innerHTML="";
return true;
}
}
//表单校验方法
function checkForm(){
//用户名
var flag1=checkNotNull("username");
//密码
var flag2=checkNotNull("password");
//确认密码
var flag3=checkNotNull("repassword");
//一致性校验
var flag4=checkPwdAndRepwd(flag2,flag3);
return flag1&&flag2&&flag3&&flag4;
}
