我正在使用Google Maps API v3将KML文件调入Google地图。这是一段时间以来一直适用于我的东西,使用简单的多边形和自定义图标(地图别针)。我现在想要增强我的实现来添加在单击图标时应该打开的InfoWindows。
在我的测试kml文件中,我有1个多边形和两个图标,每个图标都包含在一个地标中。每个地标都有相关的风格。这两个图标都有一个BalloonStyle,它将在相关的InfoWindow中显示相关文本。这两个图标将在多边形内呈现。
所有三个项目都正确呈现,并且kmlStatus返回为' OK'。但是,InfoWindow在第一个引脚上打开(Style id =" destPin"),但不是第二个(Style id =" tractPin1")。
我已在https://developers.google.com/maps/documentation/javascript/和其他相关网站上对此进行了2天的研究;所以我开始认为这要么是我缺乏理解,要么是谷歌KML实施的一些怪癖。
这是.KML文件:

...这里是将KML提交给Google的JavaScript。
// Displays the map for a given kml file
function displayMap(kmlFile) {
var mapOptions = {
position: mapCenter,
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("mapCanvas"), mapOptions);
infowindow = new google.maps.InfoWindow({}); // copied from geocodezip
var kmlOptions = {
//suppressInfoWindows: false,
preserveViewport: false
//map: map
};
kmlLayer = new google.maps.KmlLayer(kmlFile, kmlOptions);
google.maps.event.addListener(kmlLayer, "status_changed", function() {
console.log('KML status = ', kmlLayer.getStatus());
});
kmlLayer.setMap(map); // this is copied from geocodezip
} // end of function displayMap
答案 0 :(得分:0)
原来我的代码中有一个错误来渲染地图。
mapOptions对象:
cell
...在行中包含错误:
var mapOptions = {
position: mapCenter,
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
......实际应该是:
position: mapCenter,
奇怪的是,地图渲染得很好,还有kmlLayer。此外,第一个地图引脚显示其infoWindow,但该简单错误以某种方式阻止其他地标呈现其infoWindows。只是那种简单的疏忽让我花费了大量的时间;更不用说2声望。
