var yj = /^[a-zA-Z0-9]([a-zA-Z0-9]*[-_.]?[a-zA-Z0-9]+)+@([a-zA-Z0-9]+\.)+[a-zA-Z]{2,}$/; //邮件
var sj = /^1[3,5,8]\d{9}$/; //手机
var name = document.getElementById("name").value; //用户登录名
if(name.length <= 0){
alert("请输入用户名！");
}
else if(yj.test(name))
{
document.getElementById("dllx").value = '0';
}else if (sj.test(name)){
document.getElementById("dllx").value = '1';
}
--------------------------------------------------
table 里有个隐藏
<input type="hidden" name="dllx" id="dllx" />
-----------------------------------------------------
action里
private Zgsqxx zgxx; //set，get方法.
String dllx = request.getParameter("dllx");
if(dllx == "0"){
zgxx = sysLoginService.checkUserByYjdzAndPwd(user, pwd);
}else if (dllx == "1"){
zgxx = sysLoginService.checkUserBySjhmAndPwd(user, pwd);
}
问题描述：
就是想用隐藏域 判断用户输入的是邮件还是手机 。总是获取不到
在action里获取，等于0和等于1调用不同的方法。action里 应该是这样写的吧 ?
------解决方案--------------------
- HTML code
<script>function aa(){ var a = document.getElementById("dllx").value; alert(a);}function bb(){var yj = /^[a-zA-Z0-9]([a-zA-Z0-9]*[-_.]?[a-zA-Z0-9]+)+@([a-zA-Z0-9]+\.)+[a-zA-Z]{2,}$/; //邮件var sj = /^1[3,5,8]\d{9}$/; //手机var name = document.getElementById("name").value; //用户登录名if(name.length <= 0){ alert("请输入用户名！"); }else if(yj.test(name)) { document.getElementById("dllx").value = '0'; }else if (sj.test(name)){ document.getElementById("dllx").value = '1'; } }</script><input type="hidden" name="dllx" id="dllx" /><input type="text" name="name" id="name" /><input type="button" onclick="bb();" value="提交"><input type="button" onclick="aa();" value="测试是否赋值">
