Question

I’m trying to affect only elements inside the submitted form (this). This is what I’m trying right now:

$("form").submit(function (e) {
    $(this + '[name="field"]').addClass('fill-field');
    });

I also tried:

$(this).filter('[name="birthday[day]"]').addClass('fill-field');
$(this).is('[name="birthday[day]"]').addClass('fill-field');

How can this be done?

Answer 1

Use .find()

$("form").submit(function (e) {
    $(this).find('[name="field"]').addClass('fill-field') ;

    // $(this).find('[name="birthday[day]"]').addClass('fill-field');
});
