如何检索selected index value

上的test4.php

验证所有函数用于js检查

function validateAll()
{
    var Gfn=document.getElementById("firstname");
    var Gln=document.getElementById("lastname");
    var Gid=document.getElementById("uniqueid");
    var Gemail=document.getElementById("email");
    var Gpwd=document.getElementById("password");
    var Gcpwd=document.getElementById("confirm_password");

    if(Gfn.value.length === 0)
    {
        document.getElementById("FName").innerHTML="This field can not be empty.";
        firstname.focus();
        return false;
    }
    if(Gln.value.length === 0)
    {
        document.getElementById("LName").innerHTML="This field can not be empty.";
        lastname.focus();
        return false;
    }
    if(Gemail.value.length === 0)
    {
        document.getElementById("Uemail").innerHTML="This field can not be empty.";
        email.focus();
        return false;
    }
    if(Gid.value.length === 0)
    {
        document.getElementById("Uid").innerHTML="This field can not be empty.";
        uniqueid.focus();
        return false;
    }
    if(Gpwd.value.length === 0)
    {
        document.getElementById("pwd").innerHTML="This field can not be empty.";
        password.focus();
        return false;
    }
    if(Gcpwd.value.length === 0)
    {
        document.getElementById("cpwd").innerHTML="This field can not be empty.";
        confirm_password.focus();
        return false;
    }
    if(validpwd() === "error")
    {
        document.getElementById("cpwd").innerHTML="Password and confirm password does not match";
        confirm_password.focus();
        return false;
    }
    if(validemail() === "error")
    {
        document.getElementById("Uemail").innerHTML="please enter valid email.";
        email.focus();
        return false;
    }




    return true;
}
