在谷歌地图里,给了我们一个默认的标记图标,如果我们想要换成自己喜欢的logo,那就得写点代码了.这个示例当中,更换的是一"组"标记图标.

1、//Thisexampleaddsamarkertoindicatethepo衡痕贤伎sition//ofBondiBe锾攒揉敫achinSydney,Australiafunctioninitialize(){varmapOptions={zoom:4,center:newgoogle.maps.LatLng(-33,151)}varmap=newgoogle.maps.Map(document.getElementById('map-canvas'),mapOptions);varimage='images/beachflag.png';varmyLatLng=newgoogle.maps.LatLng(-33.890542,151.274856);varbeachMarker=newgoogle.maps.Marker({position:myLatLng,map:map,icon:image});}google.maps.event.addDomListener(window,'load',initialize);
2、varimage='images/beachflag.png';varmyLatLng=newgoogle.maps.LatLng(-33.890542,151.274856);设置要显示标记图标的路径及标记图标在地图上显示的位置
3、varbeachMarker=newgoogle.maps.Marker({position:myLatLng,map:map,icon:image});在google.maps.Marker里面,新增了icon属性,用来传入要显示标记图标的路径.
4、当然,也可以显示多个自定义的标记图标.f掼鸿乡羰unctioninitialize(){varmapOptions={zoom:1扉钛笆哇0,center:newgoogle.maps.LatLng(-33.9,151.2)}varmap=newgoogle.maps.Map(document.getElementById('map-canvas')mapOptions);setMarkers(map,beaches);}varbeaches=[['BondiBeach',-33.890542,151.274856,4],['CoogeeBeach',-33.923036,151.259052,5],['CronullaBeach',-34.028249,151.157507,3],['ManlyBeach',-33.80010128657071,151.28747820854187,2],['MaroubraBeach',-33.950198,151.259302,1]];functionsetMarkers(map,locations){//Addmarkerstothemap//MarkersizesareexpressedasaSizeofX,Y//wheretheoriginoftheimage(0,0)islocated//inthetopleftoftheimage.//Origins,anchorpositionsandcoordinatesofthemarker//increaseintheXdirectiontotherightandin//theYdirectiondown.varimage={url:'images/beachflag.png',//Thismarkeris20pixelswideby32pixelstall.size:newgoogle.maps.Size(20,32),//Theoriginforthisimageis0,0.origin:newgoogle.maps.Point(0,0),//Theanchorforthisimageisthebaseoftheflagpoleat0,32.anchor:newgoogle.maps.Point(0,32)};//Shapesdefinetheclickableregionoftheicon.//ThetypedefinesanHTML<area>element'poly'which//tracesoutapolygonasaseriesofX,Ypoints.Thefinal//coordinateclosesthepolybyconnectingtothefirst//coordinate.varshape={coords:[1,1,1,20,18,20,18,1],type:'poly'};for(vari=0;i<locations.length;i++){varbeach=locations[i];varmyLatLng=newgoogle.maps.LatLng(beach[1],beach[2]);varmarker=newgoogle.maps.Marker({position:myLatLng,map:map,icon:image,shape:shape,title:beach[0],zIndex:beach[3]});}}google.maps.event.addDomListener(window,'load',initialize);
5、代码解析:varbeaches=[['BondiB娣定撰钠each',-33.890笙剽茑镙542,151.274856,4],['CoogeeBeach',-33.923036,151.259052,5],['CronullaBeach',-34.028249,151.157507,3],['ManlyBeach',-33.80010128657071,151.28747820854187,2],['MaroubraBeach',-33.950198,151.259302,1]];显示多个自定义的标记图标,主要是要我们自定义一个关于经纬度及提示内容的数组.加入到title及position里面就能实现.
6、对于我们国内的开发者来说,现在访问谷歌不是一件容易的事情,这里我也只能给你们提供一些自己的小经验,还是推荐大家用百度的地图,在中国稳定性和可访问性是不需要担心的,至于百度地图效果怎么样,在后面我也会跟大家分享我的一些心得体会.如果你们有自己的一些问题我这里没有讲解到的,可以在下面进行提问.我会及时给大家解答.
