我有一个XML文件，我读到了Javascript对象。这叫做jsonXML。我在登录时可以在控制台中完整地看到对象。这是一个非常复杂的对象，有很多层和重复。
我需要访问其中一些重复的对象，但我似乎无法深入研究我需要的细节。我遇到的问题是重复的对象。
这是JS对象的结构：
我正在使用它来尝试访问对象：
console.log(jsonXML.ProfileGroup.File.Profile.WayPt);
我可以使用console.log(jsonXML.ProfileGroup.File);获取文件数组
但我无法获得单独的“文件”对象或其他任何东西。
有关此问题的任何信息都会有所帮助。谢谢！

对于那些想要看到它的人来说，这是一些加强的JSON：

文件很长，所以我在文件末尾截断它。
答案 0 :(得分：0)
我实际上环顾四周并想出如何做到这一点。我发现它是在一个不同的主题下，但我认为我可以帮助其他任何人解决这个具体问题。
要获得这些多个数组项，您必须输入如下索引：
console.log(jsonXML.ProfileGroup.File["0"].Profile.WayPt["0"].distance);
在迭代对象时，您可以使用：
files=[]; //array of file names
daters=[]; //final array of arrays
tempVal =[]; //temporary array
subArray=[]; //temporary array of sub values
var filz = jsonXML.ProfileGroup.File.length;
//depending on how many files there are, find out how many
for (i=0;i<filz;i++)
{
//add each file name to an array called 'files'
files.push(jsonXML.ProfileGroup.File[i].name);
//since in my example there are two objects called WayPt
for (j=0; j<2; j++)
{
//I use an array here to make it easy to combine into the other array
tempVal.push(jsonXML.ProfileGroup.File[i].Profile.WayPt[j].distance);
//since I have a string of comma separated values, make an array of these
subArray = jsonXML.ProfileGroup.File[i].Profile.WayPt[j].localCoords.split(',');
//combine the two above arrays
arrayNew = tempVal.concat(subArray)
push this array into the final array to use later
daters.push(arrayNew);
//reset the temporary values otherwise they will keep getting larger
tempVal=[];
arrayNew=[];
subArray=[];
}
}
当您在命名字段中有多个条目时，这是向下钻取对象的方式。
希望这有助于其他任何人！
