Popup menu and text disableing and a book question

bildx · Jan 14, 2003

Hello,

I tried unsuccessfully using previous posted thread to write a small script that will disable one the components (text field, pop-up menu). if text field ’m’ as input then pop-up menu ’d’ will be disabled and the opposite (m will be disabled if chosen d is different then value=" &quot

. Can someone assist me please?

What is the best beginner book in order to study JavaScript?

Thanks.

HTML:
<html>
<head>
<title>m/d</title>
</head>
<body>
man.
<input name="m" type="text" id="m">
dyn.
<select name="d" size="1" id="d">
<option value=" "></option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</select>
</body>
</html>

I have no idea about the disabling problem, but about the book try:
JavaScript for the World Wide Web: Visual QuickStart Guide

Disabling is not my strong field and I always finding it a problem (someone should write a cookbook).

For a book are try: JavaScript: A Beginner's Guide by John Pollock.

Hi bildx
Is this something like you are looking for?

Code:

<html>
<head>
<title>m/d</title>
<script>
function disable_m(){
	if (d.value!=&quot; &quot;){
		m.disabled=true;
	}
}
function disable_d(){
	d.disabled=true;
}
</script>
</head>
<body>
man.
<input name=&quot;m&quot; type=&quot;text&quot; id=&quot;m&quot; onChange=&quot;disable_d()&quot;>
dyn.
<select name=&quot;d&quot; size=&quot;1&quot; id=&quot;d&quot; onChange=&quot;disable_m()&quot;>
  <option value=&quot; &quot;></option>
  <option value=&quot;a&quot;>a</option>
  <option value=&quot;b&quot;>b</option>
  <option value=&quot;c&quot;>c</option>
</select>
</body>
</html>

Hi,

Thanks it open a bit my eyes, but the selection is not reversible. Meaning that if I erase manually all the content of "m” I can not choose something form “d” since it is disable. The phenomenon also occur when I choose a,b or c in the drop down list and when I choose later “ “, field text m is still disabled.

How can I solve this problem and make the selection process more flexible?

Thanks.
