Aha, Notice the Expando Which Precludes #

by why in cult

Mark Pilgrim: The UNSELECTABLE attribute is implemented as an expando. Setting the expando property of the document object to false precludes the functionality of all expandos.

Kxxxx, oh when the jargon on MSDN hits stride and blossoms into complete psychedelia.

Someone please assemble a Wikipedia page for this rare bird. I want creators’ bios. I want the original legal pads. I want pronunciation mp3s. GO!!

Is the point of this exercise to demonstrate how much you love the word expando? I can’t disagree with the fact that it is a good one. Nevertheless, your use of expando in this situation seems irrelevant to all browsers. For that, I commend you.

so in IE, the expando is not itself an expando?

If you set document.expando=false, IE will preclude the functionality of allowing unstationary to be set. Firefox precludes the preclusion of this functionality even with expando disabled. The W3C is crying now just like the Shoshone do when you throw an empty Yoohoo bottle on the ground.

I think expando is a great name for a function, but maybe not so great as a property. It seems to me like it needs to DO something itself.

There ought to be a place for it at the top of every Type or Object hierarchy.

So, let’s say, what does Object.new.expando do?

I disagree, the expando totally DOES something. Namely, it precludes other expandos.

Try setting document.expando=false in the global scope. It not only precludes the unselected attribute from being set, but also every other “arbitrary” attribute. The unselected attribute is affected by document.expando=false in the same way a user-defined attribute such as “unstationary”. Try this example in IE with expando set to false, and then set to true for clarification.


<html>
<head>
<script>
document.expando= true;
window.onload = function() {
  alert(document.body.getAttribute("unstationary"))
  alert(document.body.getAttribute("id"))
}
</script>
</head>
<body id="unstationary" unstationary="on"></body>
</html>

Expando. Every programming term sounds like English, everyone knows why. Concept of expando is rather complicated, not to say irrational, psychedelic etc. It’s funny because it complicates meaning of 1/0, true/false and other binary thingies. So the best thing to do is to name it “EXPANDO” because it doesn’t sound as English at all. Spanish? Maybe.

Handwritten code is so pretty… can someone write a compiler that takes image files? :)

Totally Spanish. Expando == I expand.

I just tried http://www.mozilla.org/newlayout/demo/expando.html and it is almost exactly to the beat of the music I’m listening to.

Creepy stuff!

Uh … just a small js thing … when comparing with undefined, you should use === instead.

sigh, my love was cleansed. it was an ascii heart. the beauty of which you may never see, now. damnable software.

turns out i was forced to disable ascii hearts on this blog due to rampant fanboyism. you’ll have to circumvent that restriction by resorting to the slightly more dated ascii: I LOVE YOU .
