I have a form with a series of checkboxes and dropdown lists. Currently the form is submitted using a button that calls a function 'postData(this)'. However, I would like to change this so that the form no longer requires a button but will submit after 3 seconds of one of the elements being changed.
If checkbox a is checked, the 3 seconds countdown will start, if another checkbox is checked in that time the 3 seconds is reset and starts again.
How would I go about introducing this?
