@等不到天亮: 

var str = "{\"FileList\": [{ \"EndTime\": \"2018-07-16 10:13:11\",\"StartTime\": \"2018-07-16 10:12:13\"}],\"FileSize\": 167}";
var obj = JSON.parse(str);

alert(obj.FileList[0].EndTime);

 

 

这样就可以   你试一下

@竜咚咚: 这个格式怎么拆分的

等不到天亮 | 园豆：23 (初学一级) | 2018-07-18 16:20

@等不到天亮:你请求这个接口  他给你返回了一个json串   你解析他这个串就行 js里用我给你的这个方法就行

 

或者你也可以在后端处理    你现在的疑惑是什么

 

这个json  两个大的节点  FileList 这个节点中是个数组  也是你要的数据

@竜咚咚: 

//var data =JSON.stringify(info);
console.log(info);
var obj = JSON.parse(info);
//console.log(data);
for(i = 0; i < obj.length; i++)
{

var endTime = obj.FileList[i].EndTime;
console.log(endTime);
}

@竜咚咚:返回的是这样的格式，filelist前面没有引号

等不到天亮 | 园豆：23 (初学一级) | 2018-07-18 16:31

@等不到天亮: 

var str = { "FileList": [{ "EndTime": "2018-07-16 10:13:11", "StartTime": "2018-07-16 10:12:13" }, { "EndTime": "2018-07-16 10:13:11", "StartTime": "2018-07-16 10:12:13" }], "FileSize": 167 };
var obj = eval(str);

for (i = 0; i < obj.FileList.length; i++) {

var endTime = obj.FileList[i].EndTime;
alert(endTime);
}

@竜咚咚: 谢谢，我知道问题了，找的那个json字段不完整。

等不到天亮 | 园豆：23 (初学一级) | 2018-07-18 16:54

@竜咚咚: 后面就没有

等不到天亮 | 园豆：23 (初学一级) | 2018-07-18 16:55

@等不到天亮: 解决了  就行

雷。 | 园豆：775 (小虾三级) | 2018-07-18 16:57

@竜咚咚: 是呀，我没仔细看，这个是个坑，我再想想这个字段哪里有返回

我这样写过，取不出来，undefind

至少要先把FileList下的数据显示出来，总是取不出来，不知道怎么写了

@等不到天亮: data[i]["字段名称"]试试。具体的也记不太清了，你可以试试

@lbx.tom: 

console.log(info);
//var o = eval(info.FileList);
var data =JSON.stringify(info);
console.log(data);
for(var i in data){
console.log(data[i].StartTime);
}

那个试过了，不行
