Firebug Error : markersArray[i].setMap is not a function

[morningstar]

I'm working on a small map app and when i try to remove markers on the
map that i had placed earlier, with the following function;

function clearLocations() {
for (i in markersArray) {
markersArray[i].setMap(null);
}
markersArray.length = 0;
}

I get the error markersArray[i].setMap is not a function and the
markers are still on the map.Help will be appreciated.
Thanks

More context please. Preferably a link to your map that exhibits the
error. The most likely cause of your problem is that the markersArray
is not in scope.

Do you have declared markersArray as global variable?
And instead of markersArray.lentgh = 0 use
markerArray = [] to initialize the array again

the map is still in my localhost not online yet.But I'm making
arrangement to upload it.
I think the markersArray is in scope, cause its a global variable and
works in other functions like the one to bring in initial markers on
the map.
I also tried the other suggestions still not working.

like this should work

      
     function clearLocations() {
         for (i in markersArray)
              markersArray[i].setMap(null);

         markersArray = new Array()
       }

if you post your map code we can help you more

Then we will need to see the patient. Give us a link when you get it
online, I would thing the problem should be obvious in a debugger.

Can't. Can't see your webpage.

markersArray is a collection of XML document elements ; these do not
have a .setMap() method.

You need to build an array of API google.maps.Marker objects if you
want to clear them later.

Ahh...thank you very much.Arrays have always been a blind spot of
mine.
