I was looking through Mozilla's JS in JS code and came across the snarf function. It's not defined in the javascript, it seems, just in the C version here. It isn't very well-commented, though. I Google searched this to no avail. Is this a standard part of JavaScript? (My guess is no.) Is it some kind of extension? What is it supposed ...

Namely, how does the following code: var sup = new Array(5); sup[0] = 'z3ero'; sup[1] = 'o3ne'; sup[4] = 'f3our'; document.write(sup.length + "<br />"); output '5' for the length, when all you've done is set various elements? EDIT: Forget the comparison to using it like a hashmap. I think this was confusing the issue. My 'problem' ...
Is there any way to create an array-like object in JavaScript, without using the built-in array?

MSIE v7 does not (in my hands) open a Modeless Dialog or trigger an onLoad event if there is a Javascript alert in the target page. The following fails in MSIE v7 but is OK in v6 (zip file of full source available if required). Would appreciate others confirming this and discussing why this should be so. index.htm (only javascript fun...
I need to know how I can search an array for some literal text and have it used as a condition whether to continue. Heres why: Each time I execute a function I am pushing the ID of the property it acts upon into an array. I need my funtion to check if that ID is in the array already and if it is, remove it and execute my other function ...
Just for the sake of experimentation, I've been trying to determine different ways to non-destructively chain window.onload functions in a web browser. This is the idea of what I have so far: var load = window.onload; var newFunction = function(){ alert("ha!"); } window.onload = function(){ load(); newFunction(); } The pro...

When the user clicks a cell in the table header, my script toggles the class back and forth between 'sorted_asc' and 'sorted_des.' I have pseudo element which adds an arrow glyph (pointing up or down) depending...

On Stackers' recommendation, I have been reading Crockford's excellent Javascript: The Good Parts. It's a great book, but since so much of it is devoted to describing the best way to use Javascript's basic functionality, I'm not sure how I can put his advice into practice without duplicating the efforts of many other Javascript programm...
