Arrays 在Google maps上的数组中的命名条目之间绘制线

我是一个javascript noob，帮帮我吧

我制作了一个包含几个城市的阵列：

var cities = [
    ['City 1', 59.326294118560725, 17.98754555000005],
    ['City 2', 57.70231523439743, 11.893682500000068],
    ['City 3', 62.39591678065696, 17.292328450000014],
    ['City 4', 59.89396160257896, 10.785116549999998],
    ['City 5', 57.10938174202619, 12.25817589999997]
    ];

我希望能够通过名字选择两个或更多的城市，并在它们之间划一条线

我发现这个代码：

var route = new google.maps.Polyline({
  path: something
  strokeColor: "#FF0000",
  strokeOpacity: 0.8,
  strokeWeight: 2,
  map: map
});

如何修改它，以便从数组中选择一两个城市，并使用这些城市的名称作为参考

var城市=[
var cities = [
    ['City 1', 59.326294118560725, 17.98754555000005],
    ['City 2', 57.70231523439743, 11.893682500000068],
    ['City 3', 62.39591678065696, 17.292328450000014],
    ['City 4', 59.89396160257896, 10.785116549999998],
    ['City 5', 57.10938174202619, 12.25817589999997]
    ];

var something = [];
for (var i=0; i<cities.length; i++) {
  if ((firstCity == cities[i][0]) || (secondCity == cities[i][0])) {
    // assume coordinates are Latitude, Longitude
    something.push(new google.maps.LatLng(cities[i][1],cities[i][2]));
  }
}
var route = new google.maps.Polyline({
  path: something,
  strokeColor: "#FF0000",
  strokeOpacity: 0.8,
  strokeWeight: 2,
  map: map
});

[City 1'，59.32629118560725，17.98754555000005]，
