Another question concerning http://code.google.com/apis/ajax/documentation/#Dynamic
I guess I should call initLoader() only once and from then on directly call loadMaps() as often as one wants. How do I best prevent the code to call initLoader() more then once (e.g. initLoader() is called whenever the user presses a button)? Will it drastically slow down the loading process of a webpage if I directly include the script initLoader() contains in the header of the page, so it is loaded right away. Or should I call initLoader() in a pageload-callback? How do I 'Make sure the DOM is ready when you call google.load with the callback option because it will try to append an element to the DOM'. ? What means the key parameter in: script.src = "http://www.google.com/ jsapi?key=ABCDEFG&callback=loadMaps"; ?
