Javascript function and combined variables, help appreciated.

[kigoobe]

Well friends, I have just found this forum thro' google, so this is my first post.

I need to move the following code as a javascript function -

<script type="text/javascript">  
        <!--
        var inter_<?=$cid?> = document.getElementById('chocQnty_<?=$cid?>');
        if (inter_<?=$cid?> && inter_<?=$cid?>.value) {
            var cqnty_<?=$cid?> = inter_<?=$cid?>.value;
        } else {
            var cqnty_<?=$cid?> = 0;
        }                  
        chocArray[<?=$countNo?>] = cqnty_<?=$cid?> + "~" + <?=$cprix?>;
        ajaxArr[<?=$countNo?>] = <?=$cid?> + "~" + cqnty_<?=$cid?>;
        subChoc('chocQnty_<?=$cid?>','totale_<?=$cid?>',<?=$cprix?>,chocArray,<?=$countNo?>,"",<?=$cid?>,ajaxArr);
    //-->      
    </script>

As you can see, I need mixed / combined variables here, like inter_<?=$cid?> (I have used php here, since the javascript is a part of the main page, till now).

However, I want to move that to an external file, and tried doing something like -

function onloadEvents(cid,countNo,cprix) {
   var inter_+cid = document.getElementById('chocQnty_'+cid);
}

It's not working. Wondering how can I get an equivalent of inter_<?=$cid?> in this function, where the value of $cid will come as a function argument.

Any help will be appreciated. Thanks.
Merry christmass to all

On the PHP page, use something like this before you add the external JS file.

<script type="text/javascript">
var cid = '<?=$cid?>';
</script>

and

window['inter_' + cid] = document.getElementById('chocQnty_' + cid);

Hi, thanks. Actually, I could not declare any javascript variable in the main page. So, I solved this differently, thanks to locdev.
