Question

我开始阅读有关自动加载谷歌地图的信息：

http://code.google.com/apis/ajax/documentation/#AutoLoading

我不清楚如何实际加载谷歌地图。

我试过了：

<script src="http://www.google.com/jsapi?autoload=%7B%22modules%22%3A
%5B%7B%22name%22%3A%22search%22%2C%22version%22%3A%221.0%22%2C
%22language%22%3A%22en%22%7D%2C%7B%22name%22%3A%22maps%22%2C%22version
%22%3A%222.X%22%7D%2C%7B%22name%22%3A%22elements%22%2C%22version%22%3A
%221.0%22%2C%22packages%22%3A%5B%22localsearch%22%5D%7D%5D
%7D&key=MY_KEY"></script>
<script type="text/javascript">
//<![CDATA[
        google.load("maps", "2.x");
        google.setOnLoadCallback(function() {
                map = new google.maps.Map2(document.getElementById("map"));
                map.setCenter(new GLatLng(37.4419, -122.1419), 6);
                map.addControl(new GSmallMapControl());
                }
        );
//]]>
</script>

但地图无法加载。

奇怪的是，如果我只是删除“autoload= ...” URL - 地图加载并正常工作。

如果我将autoload= ...保留在网址中并注释掉手动加载“google.load("maps", "2.x");”，则仍然无效。

有关如何正确使用自动加载功能获取的任何想法性能最高（延迟最少）？

您应该使用：

<script src="http://www.google.com/jsapi?autoload=%7B%22modules%22%3A
%5B%7B%22name%22%3A%22search%22%2C%22version%22%3A%221.0%22%2C
%22language%22%3A%22en%22%7D%2C%7B%22name%22%3A%22maps%22%2C%22version
%22%3A%222.X%22%7D%2C%7B%22name%22%3A%22elements%22%2C%22version%22%3A
%221.0%22%2C%22packages%22%3A%5B%22localsearch%22%5D%7D%5D
%7D&key=MY_KEY"></script>

没有别的。在您的示例中删除此后的代码
