fill an empty table

I'm trying to fill an empty table (well, actually remove everything then populate it) during an ajax call and can't seem to get it working. Here's the code I'm using:

$('#tblOtherUserResults > tbody:last').remove().append(results);

results is a valid markup of a table row, such as "<tr><td>1</td></tr>" and I've verified it is indeed valid. I've tried it without the reference to the tbody and nothing works.

any help is  greatly appreciated!

Couple things:

In the jsfiddle example you gave, you don't actually have a tbody element in there, so you're going to get a jquery result with 0 length and nothing will happen.

Though leakim's suggestion is perfectly valid, I would generally lean towards yours.  .html will kill any header rows if you have them as well, while calling the append will keep the headers in tact and just replace the body.

Main other problem with your sample, is you're also calling .remove() on the tbody, where you should be calling .empty().

.remove will remove the entire tbody element from the DOM, so you'll no longer have anything to .append() the results to.

Make sure you actually have the tbody element in there, and change the call to .empty() and it should work.

What about :
$('#tblOtherUserResults').html(results);

If it don't work, please provide a link to your page or setup one here :

Your function need to be accessible
Currently you have it in a document.ready/window.onload block

Work : http://jsfiddle.net/vL7CU/3/

Better, use jQUery to bind
Work : http://jsfiddle.net/vL7CU/4/

function insertStuff() {
    var results = '<tr><td>2</td></tr>';
    $('#tblOtherUserResults').html(results);
}

$(document).ready(function() {
    $("button").click(insertStuff);
});

Open in new window


<button>insert</button>
<br>
<table id="tblOtherUserResults">
    <tr>
        <td>1</td>
    </tr>
</table>

Open in new window

the issue was using remove() over instead of empty(). Once I switched to that it worked with the append()

the fiddle was a very quick and dirty attempt to show what i was doing attempting to do in the most simplest terms. essentially i'm making a an ajax call whenever a textbox changes and displaying the results in the table.

either way everythings working now thx

Great, glad it's working.

Should note though, the only reason I suggested against leakim's, was because it was calling .html on the whole table instead of the tbody.
Calling .html on the full tbody selecter instead of just the table would have the same effect.
I'd be surprised if there was any difference in perf, since under the covers jquery's doing the same thing, but still one method call instead of two.

Food for thought.
