我有一个包含多条折线的地图,并希望在点击该行时打开特定于行的信息页。
到目前为止,我的代码只显示了上一次迭代的内容。
我发现了两个非常好的例子,但是经过几个小时的尝试,我仍然没有进一步的发展
示例1:http://srsz750.appspot.com/api3/polylines-multiple.html
示例2:http://www.geocodezip.com/v3_GenericMapBrowser.asp?filename=flights090414.xml
所以你是我的最后一枪:-S
以下是我的代码,仅显示上次迭代的内容:
for (var i = 0; i < locations.length; i++) {
var route = locations[i]; // locations is an array of route-arrays.
//route is an array with details. route[0] contains the description.
var imageStart = 'img/rijder.png';
var polyOptions = {
strokeColor: '#0000FF',
strokeOpacity: 1.0,
strokeWeight: 3
}
poly = new google.maps.Polyline(polyOptions, info);
var path = poly.getPath();
//line text
var info = route[0];
google.maps.event.addListener(poly, 'click', function(event) {
infowindow.setContent(info);
infowindow.position = event.latLng;
infowindow.open(map);
});
//startmarker
var startLatLng = new google.maps.LatLng(route[1], route[2]);
var smarker = new google.maps.Marker({
position: startLatLng,
map: map,
icon: imageStart,
title: route[7],
html: route[0]
});
path.push(startLatLng);
//starttext
google.maps.event.addListener(smarker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
});
//endmarker
var endLatLng = new google.maps.LatLng(route[4], route[5]);
var emarker = new google.maps.Marker({
position: endLatLng,
map: map,
icon: imageEnd,
title: route[8],
html: route[3]
});
path.push(endLatLng);
//endtext
google.maps.event.addListener(emarker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
});
//close line and put on the map
poly.setMap(map);
}
}
这是我希望工作的代码,但所有行都消失了(只有相关代码,我还添加了鼠标悬停功能):
//line text
google.maps.event.addListener(poly, 'click', (function(event,index){
return function(){
var routeinfw = locations[index];
var inf = routeinfw[0];
infowindow.setContent(inf);
infowindow.position = mouselocation;
infowindow.open(map);
};
})(event,i));
//starticon
答案 0 :(得分:9)
就像您发布的示例一样,创建一个函数来创建click事件侦听器并从位置循环内部调用它:
function createInfoWindow(poly,content) {
google.maps.event.addListener(poly, 'click', function(event) {
infowindow.content = content;
infowindow.position = event.latLng;
infowindow.open(map);
});
}
你可以在循环结束时调用它:
createInfoWindow(poly,info);
