我在我的javascript中的for循环中调用谷歌地图,因为我有多个需要根据距离单独计算成本的路线。
除了仅返回其中一条路线的距离外,一切都很好。
我有一种感觉,这与我在 ajax 调用地图中声明项目的方式有关。任何想法可能是下面代码中的问题?
for (var i = 1; i <= numJourneys; i++) {
var mapContainer = 'directionsMap' + i;
var directionContainer = $('#getDistance' + i);
$.ajax({
async: false,
type: "POST",
url: "Journey/LoadWayPoints",
data: "{'args': '" + i + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
if (msg.d != '[]') {
var map = new GMap2(document.getElementById(mapContainer));
var distance = directionContainer;
var wp = new Array();
//routes
var counter = 0;
$.each(content, function () {
wp[counter] = new GLatLng(this['Lat'], this['Long']);
counter = counter + 1;
});
map.clearOverlays();
map.setCenter(wp[0], 14);
// load directions
directions = new GDirections(map);
GEvent.addListener(directions, "load", function () {
alert(directions.getDistance());
//directionContainer.html(directions.getDistance().html);
});
directions.loadFromWaypoints(wp, { getSteps: true });
}
}
});
}
