Question

There is a table, how I can get tr (table row), if there consists at least one input element.

I tried like:

$('#tablename:contains(input)').closest('tr');

It doesn’t work.

Answer 1

$('#tablename tr:has(input)')

is what you were looking for.

• Read about the :has() selector.

• :contains() will look for simple text, while :has() will look for elements that match the selector.

Or the more efficient version:

$('#tablename tr').has('input')

• Read about .has() filter function.
