Why?

[Abhishek Bhattacharya]

This's my very first code for the "Hello World of Google Maps" tutorial.

I've been trying to find errors in this since a long time, but have failed; and am stuck at the very first stage just due to this.

Can anyone make out the fault.

I guess, the fault's in the "function initialize()".

I would suggest reading this (from the v2 posting guidelines, but...):

You should be able to use the "Error Console" to see errors.

If you posted a link rather than code, we could do that as well, then
no one would have to guess.

Sir,

I actually wasn't able to understand your reply to my problem.

Could you please help me?

I hope you'd be understanding that I'm stuck in the very first "Hello world of Google Maps".

Thanks,

Abhishek

You havent specified *exectly* what issue you having. Is the map not
displaying? are you getting a message, is the map coming out green? We
dont know what issue you having.

You havent included a link you *your* webpage. Not a paste of code, a
real live page. A link. We want to view the page in a real browser.

As Barry and Larry said, it would be best to post a link to an actual map page that we can load in the browser.

But since you posted your code... Have you compared it *carefully* with the original code on this page:

http://code.google.com/apis/maps/documentation/javascript/tutorial.html#HelloWorld

Use a "diff" or "compare" program to make it easier to see what you changed, or just read the code *carefully*.

Do you see what you removed or left out from the original code? There is something important missing in your code.

Thanks,

Thanks a lot, Mike.

I was unaware of the "diff" and "cmp"!

But, one question,

after we've defined the "LatLng" coordinates, there's a "semi-colon" in the original code, but, it works without the code.

Am I right toward this? If yes, why is it then given in the original code?

Thanks,

Abhishek

Not really a maps question, but general javascript syntax

And these are examples of where you should not put a semicolon:

if( x < 5 ) {
x++;
};

this is correct but just by the way

Barry pointed you toward information about the semicolons, which are a matter of JavaScript syntax not directly related to the Maps API. As you get more familiar with JavaScript, this stuff will get easier.

But the difference I noticed was something else - in the code you posted, I didn't see anywhere that the initialize() function ever gets called. In the original example, this is done in an onload handler in the body tag - which doesn't appear in your version.

[Abhishek Bhattacharya]

Yeah,

Actually I had out here an old version of my code.

I had then added a "<body onload>" event handler.

Later, it started working by using the "cmp" service as suggested by you.

But, my questions about the semicolon was a different thing.
