Google map is not working Properly in ajax request

Hi I have one web application where i am using google map in my site. For Fetching Marker points I am using ajax request. In First time When I am using this it's working perfect but when i tried for second time 开发者_JS百科(ANY refresh). Then it's showing only half google map. I am using version 2 google map api. Please help me to find the solution. Thanks in Advance.

hard to say what is your problem here. You might want to try to redraw the map by using

map.checkResize();

or in google maps api v3:

google.maps.event.trigger(map, 'resize');

But this normaly shouldn't be needed...
