CodePudding user response：

To do what you require you can use the :has() selector to find the tr elements which contain a mark, and then find() the checkbox within them.

Also note that you don't need to 'click' the checkbox to set its state, you can update the checked property directly, like this:

$('tr:has(mark)').find(':checkbox').prop('checked', true);
