That's probably a CSS problem. If you look at the generated source of the page (View -> Page Source), you'll probably spot the difference between the two lists quickly.

You are probably calling that before the element is made. Either call it in a function on page load or just put the JavaScript after the element.

And what doesn't it do?

Because you are printing it out after the loop terminates, it actually goes from 0 to 20 and then exits, and then prints out.

Well, if you are repeating that a lot, it's not good to be calling document.getElementById so much. Storing a reference would probably be better. Short code doesn't necessarily mean it's faster.

The World's Most Misunderstood Programming Language. Particularly look at the Lisp in C's clothing bit!

Agree fully.

Interesting. The IT people I know working in those sorts of programming are generally doing technical support and some programming, but I do know I've a very limited knowledge of the...

Isn't that more engineering? And these days, to work in electronic engineering, you are most certainly better off with a degree than without it. Certainly, in the past, you could get away with...

But beware, that it's just a catchphrase, it doesn't actually mean anything, or at least won't consistently mean anything. Actual advances in technology that you could look at are HTML5 (including...

Is this a JavaScript forum? Yes.
Is this a forum for the JavaScriptMVC library? No, but there's nothing to stop you asking!

What's your question? As mrhoo said, it's still allowed occasionally for backwards compatibility, other than that, it's entirely wrong and you should never use it. Nothing to be learned.

You want the parent node's id of this script tag?
var els = document.getElementsByTagName("script"),
data = els[els.length-1].parentNode.id;

Learn one first and then the other, probably PHP first (because that runs on the server, so you'll have less browser inconsistencies. So, I think the best approach is to learn the basics, then start...

Well, in my opinion, the hard bit is the design. I don't think you would have much difficulty getting the necessary tools in a year. The most important thing, in my opinion, is to simply practice the...

Most of them aren't really languages at all.
From the start, XML and HTML are virtually the same thing, HTML can be learned in about half an hour. CSS and HTML go hand in hand, but you'd know the...

Therein lies your problem. JavaScript doesn't have classical inheritance, it has prototypical inheritance, so if you are expecting things to work like Java or C++, you will be disappointed. Even the...

Well, it depends on the type of functions. For example, I normally wouldn't apply a function to an li, but rather to the containing ul:
var...

Vim personally, I have an Apache server locally, and set up a virtual host for each project and that's about it. Git to keep track of revision, and I'll try out Continuous Integration from Eriwen in...

What Padonak said, but also:
if (a.length >= 6 && a.length <= 10)Is a little more managable!

Because it only updates the canvas onmousemove, it's not designed for such animation. You can either read through the library source and work out how to manually update it, or contact the developers...

modal.addEventListener('click', function (event) {placeDiv(event, 'orange');} );That should work, but I prefer to explicitly write it as something like:
modal.addEventListener('click', function (e)...

Yup, you need the brackets as I indicated for both if statements, works fine for me.

It would be better if you didn't simply repost your original post a few weeks later after not replying to any post on your first one!

Best of luck!

Paper.js is JavaScript, it's "ported" to JavaScript, in other words, it's written in JavaScript.

You might mean:
if ( (car == "I" || car == "J") && agec < 25)But you didn't tell us exactly what it's supposed to do!
