submit form

Hi, im quite new to ajax, so any help would be appreciated. Im building a registration page. when all of the information has been entered into the fields I would like the form to process a php page which should produce text saying "registered" or "user ID exists".

my html

	<body>
<div class="header">
</div>
<p><b><h1>User Registration</h1></b></p>

<form name="register" action="RegisterNewUser.php">
	<p>User ID:
	<input type="text" name="userID" value="" onMouseMove="javascript:validate();"> <div id="user"></div></p>

	<p><br>First Name:
	<input type="text" name="Name" value="" onMouseMove="javascript:validate();"> <div id="name"></div></p>

	<p><br>Surname:
	<input type="text" name="Surname" value="" onMouseMove="javascript:validate();"> <div id="surname"></div></p>

	<p><br>Password:
	<input type="password" name="passWD" value="" onMouseMove="javascript:validate();"></p>

	<p><br>Retype Password:
	<input type="password" name="repassWD" value="" onMouseMove="javascript:validate();"><div id="password"></div></p>


	<br>

	<input type="Submit" name="Submit" value="Submit" onClick="ajax();">
	<input type="reset" name="Reset" value="Reset">


</form>


</body>

my javascript

	<script type="text/javascript">
function  ajax(){ 
var req;
    try{
    req = new XMLHttpRequest();
} 
catch (e){
try{
req = new ActiveXObject("Msxml2.XMLHTTP");
} 
catch (e) {
try{
req = new ActiveXObject("Microsoft.XMLHTTP");
} 
catch (e){
alert("Your browser needs updating.");
return false;
       		}
		}
	}
        req.onreadystatechange  = function()
    { 
         if(req.readyState  == 4)
         {
              if(req.status  == 200) 
                        var response=request1.responseText;

         }
    }

    req.open("GET", "RegisterNewUser.php", true);
    req.send(null);
}

can anyone shed any light on where im going wrong? the submit button works how I want it to, but i do not want to have to press submit.

thank you in advance.

In my view:

when user finished entering password i.e Last form field to be filled by user then in your validate() function instantiate the ajax request to do this .
