Hey all:
Given the following code:
var ct_series = [21,23]
var cr_series = [12]
function preload()
{
for ( parm in window )
{
if ( parm.match('_se ries') )
{
alert("Found one!");
}
}
}
In firefox and mozilla I get the alerts, in IE I do not.
If I try:
function preload()
{
for (parm in window)
{
alert("Found one:" + parm);
}
}
I see the alerts in IE, so I know that IE can iterate through the
window object. But none of the alert boxes show cr_series or
ct_series. In fact, this same code in Firefox results in roughly three
times as many alerts, listing objects that were not listed when run
through IE.
Help?

Hey all:
If you've read this far, you realize that my subject line is wrong.
This is not a problem with regular expressions, but a problem with my
understanding of the window object.
I though global variables were attributes of the window object that I
could iterate through?
Maybe I should repost (double post) with a correct subject line.

The for..in loop doesn't show all of the attributes of the object.
Different browsers can, and apparently do, choose to make different
attributes visible to it.
You might be better off using a custom Object. All attributes that
you add to a custom object are visible to for..in:
var global=new Object();
global.ct_serie s = [21,23]
global.cr_serie s = [12]
function preload()
{
msg="<html><bod y>";
for ( parm in global )
Lee:
Thank you, that makes sense, I wasn't sure. So I guess IE doesn't make
global variables visible to it.
And I guess by creating a custom object, my for loop iterates through
considerably fewer items and not all of the attributes of the window
object, which is nice.

Hi All,
I'd like to "compress" the following two filter expressions into one -
assuming that it makes sense regarding query execution performance.
.... where (adate LIKE "2004.01.10 __:30" or adate LIKE "2004.01.10 __:15")
....
into something like this:
.... where adate LIKE "2004.01.10 __:(30/15)" ...

I'm kind of disappointed with the re regular expressions module. In
particular, the lack of support for recursion ( (?R) or (?n) ) is a
major drawback to me. There are so many great things that can be
accomplished with regular expressions this way, such as validating a
mathematical expression or parsing a language with nested parens,
quoting or expressions.
Another feature I'm missing is once-only subpatterns and possessive
quantifiers...
