所以基本上我有这个脚本（信用到1stwebdesigner.com和geocodezip），它计算4个位置之间的距离。 位置1，位置2，位置3，位置4。 我现在需要计算location2和位置3之间的距离。 并获得该距离并显示它并根据此公式显示价格
我该怎么做？
到目前为止，我有这个（致Rajaprabhu的积分） （Price Calculation based on the distance covered） 问题1是，我的情况公式是错误的，问题2是公式与前一次计算没有距离。
var request = {
origin:location2,
destination:location3,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status)
{
if (status == google.maps.DirectionsStatus.OK)
{
var distance = response.routes[0].legs[0].distance.text;
var duration = response.routes[0].legs[0].duration.text;
var dvDistance = document.getElementById("dvDistance");
dvDistance.innerHTML = "";
dvDistance.innerHTML += "The one way Distance is: " + distance + "<br />";
dvDistance.innerHTML += "The one way Duration is: " + duration;
//calculate the one way price using the klms
var kms = distance;
var price_1 = (kms > 0) ? 3 : 0; kms = (kms > 0)? kms - 1 : 0;
var price_2 = (kms - 14) > 0 ? (14 * 1.60) : (kms * 1.60); kms = (kms-14)>0 ? kms - 14 : 0;
var price_3 = (kms - 15) > 0 ? (15 * 1.40) : (kms * 1.40); kms = (kms-15)>0 ? kms - 15 : 0;
var price_4 = (kms > 0) ? (kms * 1.20) : 0;
document.getElementById("displayprice").innerHTML = "the one way price is: " + (price_1 + price_2 + price_3 + price_4);
}
});
现在坚持公式。 1.超过35公里的任何结果都是错误的。 2. 10公里及以下应该默认为99美元。
//calculate the one way price using the klms
var kms = distance;
console.log(kms);
var price_1 = (kms > 0) ? 99 : 0; kms = (kms > 0)? kms - 10 : 0;
var price_2 = (kms - 10) > 0 ? (10 * 5.00) : (kms * 5.00); kms = (kms-10)>0 ? kms - 10 : 0;
var price_3 = (kms - 20) > 0 ? (15 * 3.75) : (kms * 3.75); kms = (kms-20)>0 ? kms - 20 : 0;
var price_4 = (kms > 0) ? (kms * 3.50) : 0;
答案 0 :(得分：1)
google.maps.Distance对象规范
将距离表示为数值和显示字符串。
属性
文字 |输入：string |使用请求中指定的UnitSystem的距离值的字符串表示。
值 |类型：数字|以米为单位的距离。
您的距离是一个字符串：var distance = response.routes[0].legs[0].distance.text;
您应该使用数值（以米为单位）：
var distance = response.routes[0].legs[0].distance.value/1000;
