Question

Suppose my code is like this:

<td class="apple">
<div class="worm">
text1
</div>
</td>

<td class="apple">
<div class="worm">
text2
</div>
</td>

<td class="apple">
<div class="worm">
text3
</div>
</td>

How can I loop through everything with “td class apple”, and then grab the text of the div inside with id “worm”, and then set each of the .attr() as that text?

Result:

<td class="apple" title="text1">
<div class="worm">
text1
</div>
</td>

<td class="apple" title="text2" >
<div class="worm">
text2
</div>
</td>

<td class="apple" title="text3">
<div class="worm">
text3
</div>
</td>

Thank you

Answer 1

$('td.apple').each(function () {
    $(this).attr('title', $('div.worm', this).text());
});

Or this shorter version (supported as of jQuery 1.4):

$('td.apple').attr('title', function () {
    return $('div.worm', this).text();
});​
