RE: Object Required: map
1. Install Firebug in your Firefox browser.
2. Enable the Console and Script tabs in Firebug.
3. Load your page and verify that you get a map is null error.
4. Select the Script tab in Firebug, click Options and turn on the Break on
All Errors option.
5. Reload the page. It should show the map.addControl() line where the error
occurs.
6. At the top of the Firebug panel, note where it says:
showAddress search.asp()
7. Click on search.asp().
Now you should see the problem. You are calling showAddress() directly from
inline code in your page, before creating the map.
Note: Do not just use the answer I gave after those seven steps. Do not just
use Larry's answer either! We are not magicians with some special talent. We
merely have good tools.
Make sure you follow the steps, so that you are set up for Firebug
debugging. Firebug showed me the problem in 60 seconds; it can do the same
for you.
If anything wasn't clear about how to set up Firebug, give me a shout back
and I'll clarify.

I am getting a Javascript object required error and can't
seem to figure it out after hours of trying. The error is
occuring every time the showAddress function is called at the
map.setCenter line.
LINK: http://woodsite.peak-systems.net/properties/search.asp
Any help is appreciated. Thank you.
Here is a javascript snippet..
script type=text/javascript
var map = null;
var geocoder = null;
geocoder = new GClientGeocoder();
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById(map));
map.setCenter(new GLatLng(36.9, -76.2), 11);
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
}
}
function showAddress(lat_long, InfoWindowHtml) {
if (lat_long != )
{
var point = new GLatLng(lat_long);
map.setCenter(point, 11);
var marker = new GMarker(point);
map.addOverlay(marker);
marker.bindInfoWindowHtml(InfoWindowHtml);
}
}
/script
Then in the HTML I have a series of calls to showAddress like this
script language=JavascriptshowAddress(foo, bar);/script
and a map
div id=map style=width:100%;height:100%/div

Re: Object Required: map
Your showaddress is getting called, before initialize is run. Hence map
is null.

There are many ways to fix it, how you fix it depends on your understanding (and is really a basic javascript/programming question, not having anything to do with the map API). One way would be to move your showAddress calls into the initialize function so they run after the map variable is set up. -- Larry Thanks On Dec 10, 10:49 am, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: On Dec 10, 7:33 am, mosherjm [EMAIL PROTECTED] wrote: I am getting a Javascript object required error and can't seem to figure it out after hours of trying.

RE: Object Required: map
That of course is the cause of the bug, but it leaves open a mystery: How in the world did you figure that out? Do you have some magical talent at this? I spent hours and didn't find it! And of course you don't have a magical talent, any more than I do. Yet we somehow both found the problem in about a minute's work - simply because we have good debugging tools like Firebug. That's why I highly recommend not just providing the answer to a question like this, but explaining what tools you used to find it, and educating the OP on what these tools are and how to use them. To paraphrase an old saying, Give a man a bug fix, and you've fixed his bug today. Teach him how to use a debugger, and he'll be able to fix his own bug next time. :-) -Mike From: [EMAIL PROTECTED] Your initialize function which initializes the map variable is run by the body onload event which happens after the page finishes loading.

Re: Object Required: map
Thanks for your suggestions. I've made some changes to the page and it helped somewhat. Instead of calling the showAddress function inline, I am now calling it from within the initialize() function. This seems to have cleared up the Object Required error. However, in IE it is giving an javascript error at a line beyond the bounds of the page which i can't figure out and displaying no Marker points. In Firefox it is not displaying the map properly at all. I installed the Firebug add-on as suggested, but there are no errors encountered in Firefox. Please take another gander at the updated code and respond if you have any suggestions. http://woodsite.peak-systems.net/properties/search.asp On Dec 10, 12:34 pm, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: On Dec 10, 9:21 am, Michael Geary [EMAIL PROTECTED] wrote: That of course is the cause of the bug, but it leaves open a mystery: How in the world did you figure that out?
