Advice on usability for submit buttons vs onkeyup jQuery

Question

I have a webpage where i have a table of parts and column filtering inputs above each column so people can filter the parts in the table, the jQuery works on keyup so every time they type a letter it filters the table dynamically. However the people in my office, out of habit, keep hitting Enter after typing a filter text in the box, this in turn submits the form for processing. What can i do? Disable the Enter key or something similar?

Answer 1

Yes, but only block the enter on the fields that should not submit the form. Also this will need to be bound on keypress, rather than keyup.

$('#target').bind('keypress', function(e) {
  if (e.which == '13') {
     return false;
   }
});
