问题描述
我使用的是Google API，我需要做的是获得两英里的不同距离。目前，我有以下几点： - $ / $>
var start = arrObjLatLngs [0];
var end = arrObjLatLngs [arrObjLatLngs.length - 1];
var base = new google.maps.LatLng（52.781048888889，-1.2110222222222546）;
var service = new google.maps.DistanceMatrixService（）;
service.getDistanceMatrix（
{
origins：[base，base]，
destinations：[start，end]，
travelMode：google.maps.TravelMode.DRIVING ，
avoidHighways：false，
avoidTolls：false
}，callback）;
function function callback（response，status）{
if（status == google.maps.DistanceMatrixStatus.OK）{
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
for（var i = 0; i< origins.length; i ++）{
var results = response.rows [i] .elements;
for（var j = 0; j< results.length; j ++）{
var element = results [j];
var distance = element.distance.text;
var duration = element.duration.text;
var from = origins [i];
var to = destinations [j];
}
}
}
}
什么我需要有两个变量; $ runinPickup 和 $ runinDestination 包含1.）base和start（它将是$ runinPickup）和2）base和end（这将是$ runinDestination）
如果我提醒 distance ，我得到响应： -
<13.9 km $ b 5.2 km
13.9公里
<5.2 km
首先，我只想知道我如何能够只是
base 和 start 之间的距离为$ runinPickup。其次，有没有办法可以做到这一点，所以它不包括小数？因此，不是第一个值为13.9公里，它只是13。然后，我需要将它转换为英里数，我猜我一旦得到我会做如下的值： var pickup _distance = parseInt（（$ fieldPickup / 8）* 5）; ？
任何帮助将不胜感激！ ：）
您是否阅读过文档？在源数组中传递两次相同的地址： 起源：[base，base]，
destinations：[start ，结束]，
会给你两次相同的结果。这应该工作（未测试），并给你2个结果：
起源：[base]，
目的地： [开始，结束]，
为了获得里程，我建议将unitSystem设置为 IMPERIAL （尽管我找不到文件中含义的定义）：
unitSystem（可选） - 显示距离时使用的单位制。接受的值包括：
google.maps.UnitSystem.METRIC（默认）
google.maps.UnitSystem.IMPERIAL
您当然可以将METRIC单位转换为英里数。
显示两个值的示例，距离为帝国单位。

I am using Google API, what I need to do is get two different distances in miles. At the moment I have the following:-
var start = arrObjLatLngs[0];
var end = arrObjLatLngs[arrObjLatLngs.length - 1];
var base = new google.maps.LatLng(52.781048888889, -1.2110222222222546);
var service = new google.maps.DistanceMatrixService();
service.getDistanceMatrix(
{
origins: [base, base],
destinations: [start, end],
travelMode: google.maps.TravelMode.DRIVING,
avoidHighways: false,
avoidTolls: false
}, callback);
function callback(response, status) {
if (status == google.maps.DistanceMatrixStatus.OK) {
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
for (var i = 0; i < origins.length; i++) {
var results = response.rows[i].elements;
for (var j = 0; j < results.length; j++) {
var element = results[j];
var distance = element.distance.text;
var duration = element.duration.text;
var from = origins[i];
var to = destinations[j];
}
}
}
}
What I need to have is two variables; $runinPickup and $runinDestination that contains the distance between 1.) base and start (which will be $runinPickup) and 2.) base and end (which will be $runinDestination)
If I alert distance I get the response:-
13.9 km
5.2 km
13.9 km
5.2 km
Firstly, I'm just wanting to know how I can get the distance of just the distance between base and start as $runinPickup. Secondly, is there a way I can do this so it doesn't include the decimal? So instead of 13.9 km for the first value, it would just be 13.
Then I would need to convert it into miles, which I'm guessing once I can get the value I would do it as follows:
var pickup_distance = parseInt(($fieldPickup / 8) * 5); ?
Any help would be much appreciated! :)
解决方案
Did you read the documentation? Passing the same address twice in the origins array:
origins: [base, base],
destinations: [start, end],
Is going to give you the same result twice. This should work (not tested), and give you 2 results:
origins: [base],
destinations: [start, end],
To get miles I would suggest setting the unitSystem to IMPERIAL (although I can't find a definition of what that means in the documentation):
unitSystem (optional) — The unit system to use when displaying distance. Accepted values are:
google.maps.UnitSystem.METRIC (default)
google.maps.UnitSystem.IMPERIAL
You can of course convert METRIC units to miles.
Example showing the two values, with distances in IMPERIAL units. Modified from the example in the documentation.
