如何在Google地图中使用动态纬度和经度值？

时间：2017-09-07 09:51:33

标签： javascript jquery json google-maps google-maps-api-3

我使用的是Google地图API。从这里我有一个数组locations，我从中有纬度和经度值。基于这些值，我正在创建一条路线。位置变量被赋予静态纬度和经度值。我想要给出动态纬度和经度值，而不是静态值。我不知道如何让这种动态变化。请任何人帮助我/

我需要制作动态lat＆amp;来自res.travlledLocation的lng值并将其更改为以下格式：

 var locations = [
  ['Start', 12.956664, 77.696829, 1],
  ['2', 12.956604, 77.696480, 2],
  ['3', 12.956523, 77.696021, 3],
  ['4', 12.956413, 77.695380, 4],
  ['5', 12.956335, 77.695029, 5],
  ['6', 12.956230, 77.694997, 6],
  ['7', 12.956107, 77.694994, 7],
  ['8', 12.955934, 77.694970, 8],
  ['9', 12.955639, 77.694932, 9],
  ['End', 12.955380, 77.694902, 10]
];
  

我的航点标记它必须像这样

要从travlledLocation对象数组中获得所需的2D数组，可以使用map()，如下所示：

var locations = res.travlledLocation.map(function(o, i) {
  return [
    i == 0 ? 'Start' : i == res.travlledLocation.length - 1 ? 'End' : i,
    o.Travlinglatitude,
    o.Travlinglongitude,
    i + 1
  ]
});
