Google地图:如何在鼠标悬停时有效地更改标记

我想动态更改任何Google地图标记的颜色/文字。

运行代码:http://jsbin.com/odimop/edit#javascript,html,live

正如您所看到的,使用变量(var styloo)的问题是当属性发生变化时,使用该变量的所有标记都以相同的方式运行,在本例中为marker4和marker5。当地图有太多标记时,这种方法既繁琐又繁琐,因为每个标记都需要一个样式变量

我正在寻找一种使用类似的方法:this.styleIcon.color =“00ff00”;。但到目前为止还没有起作用。

有什么想法吗?请!

            function initialize() {

                var myOptions = {
                    zoom: 10,
                    center: myLatLng,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };

                var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

                var marker2 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.BUBBLE,{color:"00ffff",text:"Hover Me, this doesn't work"}),position:new google.maps.LatLng(37.5, -121.880502070713),map:map});

                    styloo.set("text","color changed");

根据StyledMarker示例,您需要使用set(property, value)方法,如下所示:

styleIcon.set("text","Elevation: " + results[0].elevation + "m");

在您的情况下,将鼠标悬停处理程序更改为:

this.styleIcon.set('color', '00ff00');
this.styleIcon.set('text', 'it does not change :(');

至于其他问题,如果两者同时发生变化,则需要为每个StyledIcon创建StyledMarker。我只想添加一个每次都返回一个新图标的函数。

function createStyle() { return new StyledIcon(StyledIconTypes.BUBBLE,{color:"#95AA7B",text:"click me!",fore:"#ffffff"}); }

var marker4 = new StyledMarker({styleIcon: createStyle(),position:new google.maps.LatLng(37.2, -121.88),map:map});
var marker5 = new StyledMarker({styleIcon: createStyle(),position:new google.maps.LatLng(37.1, -121.88),map:map});

google.maps.event.addDomListener(marker4,"click", function(o){
    this.setAnimation(google.maps.Animation.BOUNCE);
    this.styleIcon.set("fore","#ffffff");//test color
    this.styleIcon.set("color","#C2554D");// background color
    this.styleIcon.set("text","color changed");
});
