Question

I have a simple form that I need to submit automatically when text is entered.

I can use the onChange or onKeyUp without the best result.

HTML is:

Answer 1

This should work. Submits the form when nothing was typed for 500ms

var timerid;
jQuery("#fusionSearchForm").keyup(function() {
  var form = this;
  clearTimeout(timerid);
  timerid = setTimeout(function() { form.submit(); }, 500);
});
