However, despite being simple, I can't figure it out (maybe because I'm a
newbie).
I'm trying to replace a string with another string, but it simply is not
working (no error messages, just won't work).
Basically, I have a document and I'd like to every occurrence of '&&1&&'
with 'test'. Eventually the user will specify what '&&1&&' will be replaced
with, but for now I can't get this simple test to work. What am I doing
wrong?
Thanks!
<SCRIPT LANGUAGE="JavaS cript" type="text/javascript">
<!--
var sDocument = new String("This is a &&1&&.");
alert (sDocument);
sDocument.repla ce("&&1&&", "test");
// sDocument.repla ce("&&1&&", txtPrompt.value );
alert (sDocument);
//-->
</SCRIPT> 5 2153

the String.replace( ) method doesn't change the value of the string.
It creates a new string, with the replacement made:
var string1="alpha" ;
var string2=string1 .replace("alph" ,"bet");
Thanks Lee, worked like a charm!

One more question if I may. The replace function only seems to replace the
first instance of the string it's looking for. What if there are multiple
instances (for example, more than one &&1&& in my example), how can I
replace them all (keep in mind that I don't know how many there might be)?
Thanks!

The first argument to replace is more correctly a "regular expression",
rather than a simple string. Regular expressions allow such things
as wildcards and specifying that the replacement should be done
"globally", throughout the string:
string2=string1 .replace(/alph/g,"bet");
The "g" indicates "global" replacement.
Beware that some characters ("^[/", and others) have special
meaning within regular expressions.
Once again... thank you Lee! That did the trick!

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
