Question

Yes ive been told a couple of time using onclick

$('#linkId').click(function() 

instead of

<a href='javascript:showComments($displayWall[id]);'>

But then how do i store a variable in the function, like i can do with that above?

I mean if a link is like this: <a id="linkId">test</a> where can i store a variable?

Answer 1

Update:

It looks more like $displayWall is a global JS variable (otherwise <a href='javascript:showComments($displayWall[id]);'> would not work). Then this should actually work too:

$('#linkId').click(function() {
    showComments($displayWall[id]);
});

I realize now, that the following assumption is far fetched, but nevertheless:

Assuming $displayWall is a server side variable, meaning the page gets pre-processed.

You could, for example, set the ref attribute of the link to the variable value:

<a id="linkId" ref="$displayWall[id]">test</a>

and access it in the click handler:

$('#linkId').click(function() {
    showCmments($(this).attr('ref'));
    //...
});

If you are attaching the handler to one element only, you can also set the variable inside the click handler:

$('#linkId').click(function() {
    var value = '$displayWall[id]';
    //...
});
