如何使用Google API获取数组中的最近位置

问题描述

在以下代码中，您可以看到this.html附加了最近的位置作为可变字符串格式。我只想将相同的结果存储到数组中，以便可以在v-select中显示。

function distance(lat1,lon1,lat2,lon2,unit) {
    var radlat1 = Math.PI * lat1/180
    var radlat2 = Math.PI * lat2/180
    var theta = lon1-lon2
    var radtheta = Math.PI * theta/180
    var dist = Math.sin(radlat1) * Math.sin(radlat2) + Math.cos(radlat1) * Math.cos(radlat2) * Math.cos(radtheta);
    if (dist > 1) {
        dist = 1;
    }
    dist = Math.acos(dist)
    dist = dist * 180/Math.PI
    dist = dist * 60 * 1.1515
    if (unit=="K") { dist = dist * 1.609344 }
    if (unit=="N") { dist = dist * 0.8684 }
    return dist
}

var data = [{
    "code": "0001","lat": "1.28210155945393","lng": "103.81722480263163","location": "Stop 1"
},{
    "code": "0003","lat": "1.2777380589964","lng": "103.83749709165197","location": "Stop 2"
},{
    "code": "0002","lat": "1.27832046633393","lng": "103.83762574759974","location": "Stop 3"
}];

var html = "";
var poslat = 1.28210155945393;
var poslng = 103.81722480263163;

for (var i = 0; i < data.length; i++) {
    // if this location is within 0.1KM of the user,add it to the list
    if (distance(poslat,poslng,data[i].lat,data[i].lng,"K") <= 0.1) {
        html += '<p>' + data[i].location + ' - ' + data[i].code + '</p>';
    }
}

$('#nearbystops').append(html);
