Keyup only after last key with jquery

Question

I\'m coding a simple script to extract database informations on input keyup event.

The problem i have is that the keyup event is always repeated everytime the user press

Answer 1

I think if you do this with onchange event you don't need to put time interval checks. whenever you complete your input and change the focus. it triggers onchange event for you

$("input").onchange(function()
{
   //extract database info
}
