我的Google标记未显示在Google地图中

嘿我正在尝试使用Google的API创建Google地图。输入正确的代码后，标记没有显示出来。有人可以帮我找出为什么没有出现？我做了一些研究，大部分问题都是由位置问题引起的。

答案 0 :(得分：1)

您的代码中出现javascript错误：Uncaught ReferenceError: LatLng is not defined。这样：

position: LatLng(38.64936217820852, -90.53628850000001),

应该是：

position: google.maps.LatLng(38.64936217820852, -90.53628850000001),

其他评论：

  1. 您要包含两次API。不要这样做，它可能会导致问题，将所有需要的参数组合到一个调用中（v=3&ibraries=places，不再需要传感器参数）
  2. 您需要在初始化地图初始化的初始化函数中初始化您的标记
  3. 您需要初始化初始化函数中的SearchBox，其中初始化地图并且在窗口加载事件上运行，因此DOM已经呈现（document.getElementById('pac-input')无法找到该元素，直到它已经存在附加到DOM）。
