Question

Please note: I do not want to use jQuery for this (otherwise I like it)

Problem: I have come to situation where I need to do some javascript function after an user changes an input field (e.g. input type="text"). So I said to myself – I remember an onchange event – BUT onchange event runs AFTER user leaves the field, but I need the function to be called for example every time user types a character to that field. Wowhead shows nice example of what I am trying to achieve this (field with placeholder "Search within results…")

Summary: I am looking for a SIMPLE way of detecting REAL onchange event(not the classic HTML one)and through that call a JS function while not using jQuery?

Answer 1

Following is a simple way of invoking each type of Key Press on field.

input type=”text” onkeypress=”myFunction()

you can also use onkeyup and onkeydown instead of onkeypress.
