How can i update javascript with php?

[wwfc_barmy_army]

Hello.

 

I have the following code for an ajax fuction:

	var a1 = document.getElementById('1').value;
var b2 = document.getElementById('2').value;
var queryString = "?a1=" + a1 + "&b2=" + b2;
ajaxRequest.open("GET", "updatedetails.php" + queryString, true);
ajaxRequest.send(null); 
}

//-->
</script>

 

Although the problem is that i need to be able to change the variables. for example i have 1, 2, 3 fields in my database. For example this code would work in php:

while ($i <= $rowcount){
$result = mysql_query("SELECT * FROM type WHERE type_id = $i") 
or die(mysql_error());  
$qry = mysql_fetch_array($result);
echo "the variable put here";
$i = $i + 1;
}

 

Something like that, but i don't know how to get it into the javascript file. Any ideas?

 

Thanks.

do you have the rest of your ajax code, e.g. the handler to catch the return...

...
if( (ajaxconns[e].readyState == 4) && (ajaxconns[e].status == 200) )
{
var response = ajaxconns[e].responseText;
...

because whatever is outputted by the php will arrive in the responseText, then you parse it depending on how you packaged it...

The rest of the ajax code is:

 

<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;
	}
}
var MSN = document.getElementById('MSN').value;
var Yahoo = document.getElementById('Yahoo').value;
var queryString = "?MSN=" + MSN + "&Yahoo=" + Yahoo;
ajaxRequest.open("GET", "updatedetails.php" + queryString, true);
ajaxRequest.send(null); 
}

//-->
</script>

 

This is run from a submit button.

 

Thanks for any help.
