javascript - 删除数组的部分内容

Question

我正在制作一个应用程序来查找/导航到某些位置。我有这段代码，并试图删除坐标末尾的 ',0' 部分，以使其与 Google map 兼容。我会手动检查并执行此操作，但我必须处理数千个位置，因此这是不切实际的。我尝试使用 .splice() 方法但无济于事。

$scope.SiteLocs = [{
        "name": "502 Nelson St, Greenville, MS 38701",
        "visibility": "0",
        "description": "502 Nelson St, Greenville, MS 38701",
        "styleUrl": "#waypoint",
        "Point": {
          "coordinates": "-91.05636,33.415485,0"
        }

      }, {
        "name": "242 Blackhawk Trace, Galena, IL 61036",
        "visibility": "0",
        "description": "242 Blackhawk Trace, Galena, IL 61036",
        "styleUrl": "#waypoint",
        "Point": {
          "coordinates": "-90.319778,42.390862,0"
        }
      }, {
        "name": "3747 Ocean Dr, Vero Beach, FL 32963",
        "visibility": "0",
        "description": "3747 Ocean Dr, Vero Beach, FL 32963",
        "styleUrl": "#waypoint",
        "Point": {
          "coordinates": "-80.358248,27.659094,0"
        }

我不熟悉 Angular(使用纯 JS，相应调整)，但这不应该起作用吗？

SiteLocs.forEach(function(location){
  location.Point.coordinates = location.Point.coordinates.slice(0,-2);
});
