Hello,
My hair falls out!
Is it possible to retrieve the "ordering value" of the <option> that
was clicked inside a range of options ?
In other words, with something like
<option value="myvalue" >mytext</option>
is it possible to know the position of that <option> between the other
<option>s and retrieve that value through javascript ?
Here is the simplified code, where "myvar" is the variable that should
somehow become the position of the clicked option:
<html>
<head>
<script>
function g(myvar)
{
alert('You clicked on the ' + myvar + 'th option.')
}
</script>
</head>
<body>
<select name="n" onChange="g(thi s.value)">
<option value="a">111
<option value="b">222
<option value="c">333
</select>
</body>
</html>
Many thanks
Bart

I think that you are looking for selectedIndex:
....
<script>
function g(myvar)
{
// selectedIndex starts off with 0, so add 1 to meet
// human logics
alert('You clicked on the ' + ++myvar + 'th option.')
}
</script>
</head>
<body>
<select name="n" onChange="g(sel ectedIndex)">
<option value="a">111
<option value="b">222
<option value="c">333
</select>
</body>

Why using DOM when the Form object already provides you with cross-browser
compliant properties?
function g(x,myvar) {

I'm currently working with a bit of javascript to dynamically add

option in the list, and when clicked the other values aren't displayed.
Here is the code;

This is a nasty one and I can't see my way out of it.
I have a bunch of select statements in a form, and each select statement
has an onchange="do_something(this)" in it, and this works
nicely..except when there is only ONE OPTION in a given select.
It seems you cannot 'onchange' a single option!
Well, that is reasonable.
The trouble is I have no way of selecting it since the form itself is a

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
