jQuery选择器

Question

<table>
<tr num="1"></tr>
<tr id="a" num="2"></tr>
<tr num="3"></tr>
<tr num="2"></tr>
<tr num="1"></tr>
</table>

$('#a').nextUntil('tr[num > 1]')

How can I implement the above query with JQuery 1.4.2 in which the first parameter for nextUntil() is selector and not JQuery object?

I was thinking on something like:

$(some tr id).nextall().filter(function () {return $(this).attr('num') > 1;});

But if there are many tr it could take some time. Any suggestions?

Answer 1

You could the .each function:

$("tr").each(function(index, value)
            {
              if ($(value).attr('num') > 1)
              {
                // do sth. with it
              }
            });

Or maybe also by jquery additional greater than selector

:gt(index)

But this should be really tricky, filtering this way.
