带有onchange（）回调的表单输入在提交时更新

Question

I have a form with some input fields and all those fields have onchange triggered callbacks (which can be different depending on the field).

My problem is that when the form is submitted the focus is still on the last modified field and the onchange callback is not called for this field, which can lead to submit wrong values.

I am looking for a way to force the triggering on the onchange event for the last field modified but I can't determine which element it is from my submit function.

How can I achieve this ?

Answer 1

Try this

$focused_element = $(':focus');
if($focused_element.is('input')){
  $focused_element.trigger('change');
}
