Re: Remove array item

I'd tend to say that using the Array.filter method would be a cleaner way of doing it...but filter doesn't change the actual array, so you couldn't use that.

You'd think...but setting this = this.filter... actually results in an error because you're not allowed to re-assign to this.

But is that really better than the iteration and the splice?

Here. This:

Array.prototype.remove = function(item_to_remove)
{
var index;
while((index = this.indexOf(item_to_remove)) != -1)
{
this.splice(index, 1);
}
}

That'll remove all of the items that match. For instance:

var filtered = [1, 2, 3, 4, 5, 6, 5, 7, 8, 5, 9, 10];
filtered.remove(5);
document.write(filtered);

1,2,3,4,6,7,8,9,10

Better:

Array.prototype.remove = function(item_to_remove)
{
var index;
while((index = this.indexOf(item_to_remove)) != -1)
{
this.splice(index, 1);
}
return this;
}

That way you can do:

var filtered = [1, 2, 3, 4, 5, 6, 5, 7, 8, 5, 9, 10].remove(5);
document.write(filtered);

Andrew: Here's the JS Array Object documentation that lists what functions Array does have. As you can see, map is in there. And I think reduce is kinda like every: http://developer.mozilla.org/en/docs/Core_JavaS...

Re: jQuery and GreaseMonkey

Same trick we use in CPhog:

var theScript = document.createElement("script");
theScript.src = "http://jquery.com/src/latest.js";
theScript.language = "javascript";
document.body.insertBefore(theScript, document.body.firstChild);

:)

I even opened up Firebug to try it out...it works. :)

Yeah. That's actually a better idea. It was kinda late last night when I wrote that. ;)

Another thing that breaks-ish is that if you include all sites with that user script, then secure sites won't be marked as secure because some items aren't secured.

Heh. It's always kinda weird to find out what other CPians sound like.

Re: On buying WinZip

Bleh. WinZip sucks. 7zip is where it's at. Even if you never use the archive browser, the shell integration is so powerful it's ridiculous. And fast too...freaking fast.

This wouldn't be that hard. You'd have to host Gecko (look to Camino for hosting Gecko in a Cocoa environment) and hook the Dock. That's about it.

Also, you can use the Gmail notifier. You'd just have to hack the JS inside the XPI (which is just a zip file with a different extension). I'm sure it's just a matter of pointing it at a different domain.

Dude. That's awesome. Thanks for linking to that, Paul. :)

You realize that TMP is one of the worst trek movies of them all...right?

Wrath of Khan, of course, more than makes up for its deficiencies. But seriously, TMP always feels like they tried to take a one hour episode and turn it into a feature length film. And they half succeeded, but only by interspersing several 10 minute musical overtures between bits of dialogue.

BTW, I managed to score the box set of all the directors cut ST films for about $35 the other day when Borders was doing a 40% off all box sets promotion. :-D
