AJAX problem

[JamieJelly]

I have basically ripped apart an AJAX tutorial so I can use it for my own devices. However, the code I have come up with doesn't work!

Can anyone see what is wrong with this code? What is supposed to happen is when someone finishes entering their telephone number, a PHP script is called which stores the information in a DB.

...
<script type="text/javascript">


var requester = null;
var formRequester = null;

window.onload = init;




/* Initialisation for JS capable browsers */
function init()
{
	/* declare form variables as JS variables */
	var fullName = document.getElementById("fullName");
	var telNumber = document.getElementById("telNumber");

	telNumber.onchange = onchangeTelNumber;
	telNumber.onblur = onchangeTelNumber;
	orderForm.onsubmit = checkForm;

	return true;
}

function onchangeTelNumber()
{
	if (requester != null && requester.readyState != 0 && requester.readyState != 4)
	{
		requester.abort();
	}
	try
	{
		requester = new XMLHttpRequest();
	}
	catch (error)
	{
		try
		{
			requester = new ActiveXObject("Microsoft.XMLHTTP");
		}
		catch (error)
		{
			requester = null;

			return false;
		}
	}

	requester.open("GET", "incompleteform.php?fullName=" + fullName.value);
	requester.send(null);

	return true;
}

</script>
...
<form>
	<fieldset>
		<legend>Step 1: Personal Details</legend>
			<label for="email">Email Address (where you want the quote sent to)</label>
			<input type="text" id="email" name="email" class="text" title="email address" />
			<label for="fullName">Full Name</label>
			<input type="text" id="fullName" name="fullName" class="text" title="full name" />
			<label for="houseNumber">House/Flat Number</label>
			<input type="text" id="houseNumber" name="houseNumber" class="text" title="house number" />
			<label for="postCode">Postcode</label>
			<input type="text" id="postCode" name="postCode" class="text" title="postcode" />
			<label for="telNumber">Telephone Number (to prevent ID theft)</label>
			<input type="text" id="telNumber" name="telNumber" class="text" title="telephone number" />
			<input name="submit" type="submit" value="submit" />
	</fieldset>
</form>
...

At the moment the code is only supposed to call the PHP script with one form variable just so I can get it working, but I can't even manage that!

Any help? thanks

Hi there. It looks like you have nothing triggering the javascript. You can try adding an "onchange=" tag to the <input> tag for the telephone number.

-- <input type="text" name="telephone" onchange="return jsFunction()">

Thanks, I have managed to work it out though. The variable I was trying to send to my PHP script wasn't defined in the function.

The onchange event is in the init function
