Problem executing document.write() function via ajax

Hi all,

I am having an issue with my ajax returning value generated by javascript. Understand that when Ajax calling a file (lets say .php) which contains of javascript, the return value would be in plain text (which means that the <script> will not be running) so that I have created the code as attached in snippet to replace <script> with <script type='text/javascript'> to force the javascript function to run properly.

However right now I am having issue of returning value from javascript using document.write() to the divId.innerHTML in my mainpage. What I suspect is that document.write() will overwrite my entire main page rather than only the divId.innerHTML so when ajax returning the document.write(), it stops the operation - which problem that I am having right now.

FYI: I am able to use any function in javascript properly (such as alert() ), but not document.write(). I tried to use document.getElementById(divId).innerHTML = 'theStringValue', it can run properly, but due to a reason that I need to call another function which force me to use document.write so I drop this idea by using document.getElementById.

This issue has struggled me for the past 24 hours. Your help would be very much appreciated.

Thanks
function setAndExecute(id, result){  
	var divId = document.getElementById(id);
	divId.innerHTML = result;
	var x = divId.getElementsByTagName("script");
	var h = document.getElementsByTagName("body")[0];
	for(var i=0;i<x.length;i++)
	{
		var s = document.createElement("script");
		s.type="text/javascript";
		h.appendChild(s);
		s.text=x[i].text;
	}
	alert (s.text);
}

Try to redefine the function before the AJAX call, then from inside that function you can call multiple functions (if you want)

document.write = function(text) {
  alert(text); // or whatever
}

Hi xyp, I tried however it does not work also, it seems like I found out that people also unable to solve this kind of situation until they use iFrame.

No idea if there is a way to pass value from document.write() to a specific id.innerHTML via ajax

Hi Xyp,

Yes this is what I am looking for, appreciate it very much. However I am having a problem right now as it runs the entire script and document.write() has replaced entire page of the MainPage instead of the id.innerHTML. So i think I would go for frame instead then.

Anyway thank you so much for your assistance.
