javascript onchange event

[azopardo]

Hi, I want to read a javascript text field just when it change its value to grab the value. Now I´m working with a while loop, but it is very CPU consuming. Is there other way to do? Perhaps using an onchange event of the field.

Here is my code:

$oIE = _IEAttach ($url,"URL")
$idUsuario="user_index_page_340"  ; ID name of the javascript text field
$oUsuario = _IEGetObjByName ($oIE,$idUsuario  )

While 1
    $Usuario = _IEPropertyGet($oUsuario, "innertext")
wend

I would guess the way you are doing it is ok but adding a sleep in the while loop will reduce the cpu load a lot if you haven't already done that. Say Sleep(100) on the basis that most people can't type more than 10 characters a second.

Thanks Martin, I have tried that, the text field is continuesly changed by the web page itself, and I have to trigger a posterior function on that change so I was hoping there was an "onchange" event to make it easier.
