我已经创建了一个方向模板文件,专门利用谷歌的方向。我让剧本在Magento外面工作。不幸的是,当我将脚本移动到page/directions.phtml控制台时,会返回以下错误:
“未定义的ReferenceError:谷歌没有定义”
当我尝试单击触发calcRoute()函数的test时,会得到以下错误:
“未定义TypeError:不能调用未定义的方法‘路由’”
我认为这些错误与Google调用有关,但是图形地图在页面上显示和运行都很好。这些错误具体涉及调用google.maps.DirectionsService()来定义下面所示的javascript第2行中的directionsService,并在最后调用directionsService.route。两者都与方向有关。
为什么地图会显示,但当脚本在我的html测试中工作时,方向会抛出错误?我真的很困惑。
Javascript
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function directionsMap() {
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(38.77627, -95.910965);
var mapOptions = {
zoom:4,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: chicago
}
map = new google.maps.Map(document.getElementById('map-directions'), mapOptions);
directionsDisplay.setMap(map);
//Place Markers
var baldwinsvilleMarker = new google.maps.Marker({
position: new google.maps.LatLng(00.00000, 00.00000),
map: map,
title:"store location 1"
});
var sacramentoMarker = new google.maps.Marker({
position: new google.maps.LatLng(00.00000, 00.00000),
map: map,
title:"store location 2"
});
var stLouisMarker = new google.maps.Marker({
position: new google.maps.LatLng(000.00000, -000.00000),
map: map,
title:"store location 3"
});
var catersvilleMarker = new google.maps.Marker({
position: new google.maps.LatLng(00.000000, -84.000000),
map: map,
title:"store location 4"
});
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById("get-directions"));
}
function calcRoute() {
console.log("calcRoute ran")
var start = document.getElementById('start').value;
var end = document.getElementById('end').value;
console.log(start + ' ' + end)
var request = {
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});

您应该一步一步地进行调用,例如:
body onload=directionsMap()中发射style,而不是装载style。我认为你的主要问题是,在谷歌完成加载之前,你正在调用directionsMap()函数。
因此,我认为在directionsMap()加载事件中调用jQuery更好的选择如下:
$(function() {
directionsMap()
});https://stackoverflow.com/questions/15511713
