我有一个代码，用于切换按类别标记的可见性，这很好用（请参阅下面的代码）。按类别选择标记并将fitbounds选择到可见标记
我现在想什么和不能弄清楚如何：
每个显示/隐藏一个markergroup后，我想变焦和地图的中心进行调整，以显示所有可见的标记。
我已经发现了另一个代码fitBounds()，但不要设法得到两个一起工作（我绝对新Javascript）。
我发现刚装修界于可见光标记的例子，但不与显示/按类别隐藏标记组合。 （如Center/Set Zoom of Map to cover all visible Markers?）
这里的两个代码示例：
显示/隐藏标记按类别：
function xmlParse(str) {
if (typeof ActiveXObject != 'undefined' && typeof GetObject != 'undefined') {
var doc = new ActiveXObject('Microsoft.XMLDOM');
doc.loadXML(str);
return doc;
}
if (typeof DOMParser != 'undefined') {
return (new DOMParser()).parseFromString(str, 'text/xml');
}
return createElement('div', null);
}
var infoWindow = new google.maps.InfoWindow();
var customIcons = {
monumento: {
icon: 'http://maps.google.com/mapfiles/ms/icons/blue.png'
},
hotel: {
icon: 'http://maps.google.com/mapfiles/ms/icons/green.png'
},

icon: 'http://maps.google.com/mapfiles/ms/icons/yellow.png'
},
museus: {
icon: 'http://maps.google.com/mapfiles/ms/icons/purple.png'
}
};
var markerGroups = {
"museus": [],
"monumentos": [],
"restaurantes": [],
"hotel": []
};

var map = new google.maps.Map(document.getElementById("mapCanvas"), {

var infoWindow = new google.maps.InfoWindow();

嗨Mosh Feu， 谢谢你的评论！ 这里是第一个代码的jsfiddle：http://jsfiddle.net/YEPB7/6/ 这是否有帮助？ – gliitschi8
