我有关于我的自定义地图的方向。但是,我希望添加我在 Google 开发者网站上找到的下拉菜单,该下拉菜单允许选择“自行车”、“驾驶”、“公交”、“步行”等选项。
这是我调用函数的代码,我不知道它们在哪里:
var map;
var gdir;
var geocoder = null;
var addressMarker;
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
gdir = new GDirections(map, document.getElementById("directions"));
GEvent.addListener(gdir, "load", onGDirectionsLoad);
GEvent.addListener(gdir, "error", handleErrors);
setDirections(document.getElementById("fromAddress").value, document.getElementById("toAddress").value, "en_US");
}
}
function setDirections(fromAddress, toAddress, locale) {
gdir.load("from: " + fromAddress + " to: " + toAddress,
{ "locale": locale });
}
这是网址,我认为我需要将其放在我所拥有的某处。
--我想我可以先用一种模式来测试它,比如“WALKING”。然后在它起作用后添加下拉。
======================================
我在以下网址找到了这个网址: https ://developers.google.com/maps/documentation/javascript/examples/directions-travel-modes
==========================================
function calcRoute() {
var selectedMode = document.getElementById('mode').value;
var request = {
origin: haight,
destination: oceanBeach,
// Note that Javascript allows us to access the constant
// using square brackets and a string value as its
// "property."
travelMode: google.maps.TravelMode[selectedMode]
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
这是在上面的代码中,我想使用它 travelMode: google.maps.TravelMode["WALKING"]
