Hi hubbs,
1. If you want to throw an alert, you could do it like this:
$(document).ready(function() {
$('table').click(function(event) {
var $thisCell, $tgt = $(event.target);
if ($tgt.is('td')) {
$thisCell = $tgt;
} else if ($tgt.parents('td').length) {
$thisCell = $tgt.parents('td:first');
}
// now do something with $thisCell
if ($thisCell) {
alert('hello');
}
});
});
Definitely take a look at Matt's post, though. It's a more robust
solution.
2. The ':first' selector is there in case you have nested tables.
It'll select the one closest to event.target.
3. If you don't want anything to occur when clicking on a link's
nested spans, then you don't have to check for parents or anything
like that. It's much easier. Is it all links in the document? All
links in a table? Anyway, you could do something like this:
$('table').click(function(event) {
if (event.target.nodeName.toLowerCase() === 'a') {
event.preventDefault();
// do something
}
});

I was reading a great post on learningjquery.com about event
delegation, and it gave an example of how to account for child/
descendants that might get clicked.
Here is the example show:
$(document).ready(function() {
$('table').click(function(event) {
var $thisCell, $tgt = $(event.target);
if ($tgt.is('td')) {
$thisCell = $tgt;
} else if ($tgt.parents('td').length) {
$thisCell = $tgt.parents('td:first');
}
// now do something with $thisCell
});
});
My question is, how do I do something with $thisCell? I must be
missing a step here, what is I wanted it to throw an alert?
Also, what is the :first doing in this situation? Say, I have a link
that has a few nested spans inside, how could I ignore the clicks on
those spans, and only register it as a click on the anchor?
