Embedding a Google map

I have embedded a Google Map in my website. I want to change its location according to user input. How can I do this?

I tried to copy the link of the location and assign it to the iframe src:

    $("iframe").attr("src", "https://maps.google.co.in/maps?q=USA&hl=en&ll=37.09024,-95.712891&spn=131.016476,346.289063&sll=23.259933,77.412615&sspn=0.178842,0.338173&oq=usa&doflg=ptm&hnear=United+States&t=m&z=2");

but the iframe is not loading the map.

Try to use the GoogleMaps JavaScript API. The offer way more control (geocode, searching, custom marker, etc...) over the map then just embedding a iframe.
