Need some help from javascript gurus, javascript events and conditions

[kigoobe]

Hi guys

I am having a select command like this -

<select name="nlone" id="nlone" onchange="ajaxFunction()">

What I want, is that the function ajaxFunction() should be called onLoad first. Then, once user selects a value the onChange event should be called, calling the same function, of course.

Any idea? Thanks.

Edit:

I don't have the body tag in my disposition here, so I can't use the onload in the body tag, I have to use it somewhere inside the page.

sounds like what you want is the following code which should be inserted in the head off your document

<script type="text/javascript">
window.onload = function(){
  ajaxFunction();
}
</script>

yes, but I can't use the body tag or anything above ... since for those i'm using a common php include. I've to call it somewhere inside the body.

Edit:

Well, I put it inside an image tag, but seems there's some problem somewhere ... it's not working as I want ...

Basically, this is a part of my ajax code that I want to execute

	box = document.forms[0].nlone;
	var age = document.getElementById('nlone').value;
	<? if ($thisq!='') { ?>
	if (age == '') {
	age = <?=$thisq?>;
	} 
	<? } ?>
	var queryString = "?q=" + age + "&sid="+Math.random();

Means, I am trying to play with three conditions

1. If there is no $thisq (php variable) and no age (javascript variable), then load tha page normally
2. If there is $thisq but no age, make age = $thisq and execute the page
3. If there is age, irrespective of whether $thisq is set or not, execute the page

Now, when I am having the value of age, (ie, onchange in select), the function works as I want. However, when the page loads with a $thisq value, nothing happens.

Below is the full ajax code -

<script language="javascript" type="text/javascript">
<!-- 
//Browser Support Code
function ajaxFunction(){
	
	var ajaxRequest;  // The variable that makes Ajax possible!
	
	try{
		// Opera 8.0+, Firefox, Safari
		ajaxRequest = new XMLHttpRequest();
	} catch (e){
		// Internet Explorer Browsers
		try{
			ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try{
				ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e){
				// Something went wrong
				alert("Your browser broke!");
				return false;
			}
		}
	}
	// Create a function that will receive data sent from the server
	ajaxRequest.onreadystatechange = function(){
		if(ajaxRequest.readyState == 4){
			var ajaxDisplay = document.getElementById('ajaxDiv');
			ajaxDisplay.innerHTML = ajaxRequest.responseText;
		}
	}
	box = document.forms[0].nlone;
	var age = document.getElementById('nlone').value;
	<? if ($thisq!='') { ?>
	if (age == '') {
	age = <?=$thisq?>;
	} 
	<? } ?>
	var queryString = "?q=" + age + "&sid="+Math.random();
	ajaxRequest.open("GET", "getlivra.php" + queryString, true);
	ajaxRequest.send(null); 
}

//-->
</script>

you can still use the code in my previous message just place it where ever you can in the body, the code will still execute when the page loads.

Thanks Mortimer. I've put that inside an image tag, but it seems there's a problem somewhere ...

Edit:

It's working now ... I had to refresh the page ...
