What? - That's All I Can Say

 

Your going to have to explain what your wanting or what your having problems with or errors or something.

in my html I have a line saying:

 

<div id="full<?php echo $news['newsid']; ?>"> </div>

 

say $news['newsid'] is 15

 

there is a link called Read More:

 

<div id="readmore<?php echo $news['newsid'];?>"><a href="#" onClick="readmore('<?php echo $news['newsid']; ?>'); return false;">Read More</a></div>

 

 

When they click Read More, It access the function and grabs Info from a PHP file.

Then whatever is returned, should be placed in

 

<div id="full<?php echo $news['newsid']; ?>"> </div>

 

but I can't figure out in the JS:

document.getElementById("full").innerHTML=xmlHttp.responseText; 

 

how to make full+str work so it will say "getElementByID("full15") technically

You need to set the entire id with a parameter and then this will work.

 

Example:

 

<script language="javascript">
function readmore(from)
{
document.getElementById(from).innerHTML = xmlHttp.responseText;
}
</script>

<div id="readmore<?php echo $news['newsid'];?>"><a href="#" onClick="readmore('<?php echo $news['newsid']; ?>'); return false;">Read More</a></div>

 

Do something to this extent and I think it will work the way you want it to.
