[FX.php List] [Poll] Which ajax implementation do you use?

Thu Oct 4 19:47:06 MDT 2007

Joel,

You do not have to write multiple functions for LAJAX to target  
specific divs.

If you have a function as such:

var targetDiv = null;

function updateDynamic()
	{
		var updateDIV = document.targetDIV;
		if(Lajax.state() == 4) {
			document.getElementById(updateDIV).innerHTML=Lajax.result();
		} else {
			document.getElementById(updateDIV).innerHTML="Please wait...";
		}	
	}

Your LAJAX request could then be:

<a href="javascript:document.targetDIV='update<?php echo  
$currentRecord; ?>';Lajax.post(url,updateDynamic,{parameters};">Link  
text here</a>

With the targetDIV being a unique DIV ID and the Lajax.post or  
Lajax.get targeting that div. One function to cover all your bases.

Hope this helps.
