Why when I write Javascript, it don't work in the browser?

Question

I'm self-taught Javascript, HTML, and XHTML. HTML and XHTML work very well. But, when I write Javascript, it doesn't work though my IE tell me there is Active Control X in my site. I copied a Javascript from a site and put it in Notepad and it worked, so the problem is not in the browser, I think it's in my Javascipt. This is a sample, check it for me pls.:
var time=get hours()

if(time>5)
{
document.write:("Not Twilight yet, sir!!!")
}

Pls. read the details carefully. The 1st, 2nd, 3rd, and 5th answers tell me that there is a problem that would stop all my Javascipt, nevertheless only Javascript written by me don't work.!!!

Answer 1

There's shouldn't be a colon there.

Answer 2

first of all, you need to remember that javaScript is case sensitive, that means that get hours() is not the same with getHours() (which, by the way, is the correct function name). If you really want to learn javascript, I recommend you the w3schools site, which, in my opinion is the most compete javaScript reference. However, I recommend that you use javascript only when necessary, because not all of its functions are cross-browser compatible. For more details, see the w3schools site.

Answer 3

Download and install Netscape Browser. The javascript console is an excellent debbuging tool for javascript.

Answer 4

JavaScript can be used to deliver viruses via web sites, so newer browsers are now blocking certain parts of their code in order to keep people safe.

With CSS, PHP and other languages JavaScript will soon become obsolete.

Answer 5

i think with the newer browsers you have to enable the browser to run the script on each and every site load.

Unfortunately this make Javascipt a dying breed.....

Answer 6

var time=get hours()

is invalid syntax and just wrong for so many reasons!!!

try
var curdate = new Date()
var time = curdate.getHours()

It's amazing how many 'experts' blew this completely!!!
