View Full Version : pressing[activating] a button with a text field

Does anyone has an idea how to
activate the button every time I type something in the textfield. [onkeyup,down,etc]

What this button does is that when it's pressed it passes any value i give it to
the textarea.

<form name="inputForm">

<input type="text" size="10" >

<input type="button" value="button" onClick="JavaScript:document.inputForm['test1'].value+='MY TEXT';">

<textarea name="test1"></textarea></form>

Something like this? But it's not working... and I don't know why...


function chkButton() {
if (document.inputForm['txtBox'].value = "")
document.inputForm['thebutton'].disabled = true
document.inputForm['thebutton'].disabled = false

<form name="inputForm">

<input name= "txtBox" onChange="chkButton()"
type="text" size="10" >

<input name="thebutton" type="button" value="OK"

<textarea name="test1"></textarea>

close, but actually I want to run whatever onclick function the button has
everytime I type any word in the input box.

In this next link sample that I give there are some input boxes on top of the DrawTable button and some other boxes in the bottom. the values for those boxes come from different javascripts but when I press the DrawTable button,
i get the result in the parent frame from all the input boxes combined.

This is the link of a prototype of my purpose (http://centurion.goldeye.info/ddd/table-maker%20frames.html)
