Trouble passing html form input to js for validation

Tuesday, April 8, 2014


I want to pass the form input that the user has entered to the variables in the js function so that it can validate the values to ensure it is appropriate to be used as an email address. My end goal is to program the form to accept a phone number(input tag) and combine it with the text of the option selected of the drop-down menu, so that it can be used as an email address. Once submitted I want to pass the address to the js to ensure it is formatted correctly and then once it is send it to a php file to be emailed to a gmail account i set up. In short a subscription page but for phone numbers that enters it into a contact list in gmail. I am using Dreamweaver CS6. what am i missing and what do i need to tweak?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Subscribe Page</title>
<script type="text/javascript"> function validate(number,carrier) {
var number = document.getElementById("number").value
var carrier = document.getElementById("carrier").value
      if (number=="") {
 alert("please enter phone number, it should be 10 numbers long")
return false;
  else function join(number,carrier) {
 return number + carrier;
 return true;
     var myresult = number.concat("carrier");
return myresult;


    <form action="" method="post" id="subscribeForm" >Phone number:<input name="number"  type="text" />
<select onchange="validate(number)" id="carrier">
<option id="verizon"value="">verizon</option>
<option id="att" value="">att</option>

<input type="submit" onclick="formsendscript.php" />

Thank you for the help!
