我想读取与此代码存储在同一目录中的JSON文件。我需要检索GPS信息并用它在地图上绘制标记。但是，运行代码后没有出现任何内容。这是我的JSON文件。

变种地图; 函数初始化（）{// 删除 “VAR地图=” 替换为 “地图= ...” } – HoangHieu

@HoangHieu仍无法加载.. – Marilynchua

http://jsfiddle.net/ 发布您的代码示例到这里:) – HoangHieu

如果你的Json数据是真的，你的代码获取数据:)。

//with for(var i in data) // i.GPSLatitude; 
//with for(var i =0; i< data.length; i++) // data[i].GPSLatitude;

变化

它仍然无法工作。是否因为在JSON文件中，GPSLatitude和GPSLongtitude是这种格式？ “GPSLatitude”：“33 deg 51'21.91 \”S“， ”GPSLongitude“：”151 Deg 13'11.73 \“E”， – Marilynchua
