validate "Src" attribute value of "iframe" element

Question

I have a iframe element to display an address in google map as below as example.

"<iframe name='testiFrame' id='runtimeIFrame' src='"https://www.google.com/maps/xyz/dfgfdg/ + "'></iframe>"

Issues:

1.Sometime some error with the "SRC" attribute value so giving error page as: The Google Maps API server rejected your request. Invalid request.

2.Some time google map unable to detect the address so displaying only map without pointing to any address.

How can i programatically detect these above two problem.

N.B: Here I cann't check the Src attribute value with "GetResponse()" method of HttpWebrequest as the Value in the attribute need to be passed in Iframe element for google map

I would suggest you can change the way to display the google map like below: http://stackoverflow.com/questions/18190813/how-to-load-a-google-map-in-an-iframe-with-javascript

Nothe URL(ie SRC attribute value for google map)cann't be checked for status of the web request as it should always need to pass through a ifram element.

Why don't you go with ajax calls using JQuery. If you go with it you can figure it out the exact error for the response and inject your the response to the iframe. Let me know your thoughts! Hope this helps a bit to forward!
