[RESOLVED] Help with dynamic updating

[jdonice]

Hi

I am looking to populate a bunch of links which appear in a table cell, these are populated using a database query.

What I would like to do is be able to click the link and in the cell below pull relevant information from the database into that cell without having to refresh the page... I think I am barking up the "Ajax" tree here but can anyone tell me if they have tried this way of building a site and if they could point me to a good example that I could learn from.

Thanks in advance

Cheers for that , and a speedy response.
I have it working and writing to a cell in my table which is cool, but I would like the abilty to write to an additional cell (with a different div tag) at the same time.

So I would like a method of building multiple requests, whats the best approach to this as my javascript knowledge is v limited.

Okay I have sussed handling multiple SPan IDS in my jscript
Using an array where element "i" contains the span id and "i+1" contains the text image url etc.

Using the following to wrtie it to the web page:

document.getElementById(update[0]).innerHTML = update[1];
document.getElementById(update[2]).innerHTML = update[3];
document.getElementById(update[4]).innerHTML = update[5];
document.getElementById(update[6]).innerHTML = update[7];
document.getElementById(update[8]).innerHTML = update[9];

Which works fine; However I would prefere it in a loop anc thought it would be simply;

do {
      document.getElementById(update[i]).innerHTML = update[i+1];
      i++;
} while ( i <=8 )		

But this gives me an error saying "is null or not an object";

I tested the loop for one line ie setting the value of i it will loop till to "0" and this worked... So I am bit confused.. Any pointers?
