There could also be other problems, but there's a syntax error here:

var m=document.forms["jobseekeruser"]["emailid"].value;
if (m==null || m=="")
{
alert(Emailid must be filled out");
return false;
}

You need an opening " mark:

var m=document.forms["jobseekeruser"]["emailid"].value;
if (m==null || m=="")
{
alert("Emailid must be filled out");
return false;
}

Then here:

var mexp =/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/
if(!mexp.test(document.jobseekeruser.emailid.value))
alert("Enter Valid username")
else
("OK Emailid is correct")
}
}
</script

Should be:

var mexp =/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/
if(!mexp.test(document.jobseekeruser.emailid.value))
alert("Enter Valid username")
else
alert("OK Emailid is correct")
}
}
</script>
