Firefox issue

[Lawrence]

I am using the Google Map API to display driving directions based on
an address entered into a form that I have to do some calculations on.
To submit the form I call the JavaScript function codeAddress and then
use window.location to redirect to my map display page and have
JavaScript and VBScript mixed together to render the driving
directions with some mass transit schedule information.

This all works fine in IE. However in Firefox the map initializes fine
but will only occasionally render the driving path and text
directions.

Any suggestions?

Here is the link:

Thank you.

As firefox has much more useful debugging tools than IE, I have to
ask:
Did you look at the Error Console (Tools:Error Console or Ctrl-Shift-
J)?

There seem to be some obvious ones, like:
Error: directionsDisplay is not defined

"directionsDisplay is not defined"

declare directionsDisplay as global, it should fix the problem!

In Javascript all vars are global !

However, your directionsDisplay var is defined just after script
loading (script tag) ; it should be set in the Initialize function,
which is called when the page (including all its scripts) has finished
loading.

If you directly call API functions just after the <script type="text/
javascript" src="http://maps.google.com/maps/api/js?sensor=false"></
script>, the Maps API generally has not finished loading when
executing the following code.

That's why we are using the Body onLoad event, to differ code
execution until the page/scripts are all loaded.

am63: "In Javascript all vars are global !"


javascript has an easy variable scope with global and local variable
http://www.webdevelopersnotes.com/tutorials/javascript/global_local_variables_scope_javascript.php3

example

1. var directionDisplay = 10;
2. disp_a();
3. function disp_a(){
5.   var directionDisplay; <--- directionDisplay is local

6. }

Thanks for the assistance everybody. The issue was not with the global
var. Since that was named outside of a function it was global. What I
had to do was call the initialize function before my map call. I
originally had the initialize function called in my html body onload.
Apparently in Firefox, the Javascript is run before the HTML, as
opposed to IE which runs all of your HTML first. I was unaware of
this. The page works great now!

Thanks to Google for a great API tool. I especially appreciate the
bicycle path, and look forward to when the transit data is available
through the API.


Thanks again to all!
Lawrence
