我正在尝试迭代响应中的第二级 json 值。
这是 Json 的示例:
{
"Links": {},
"Items": [
{
"WebId": "A0EUfSms148rEStZ8_fh",
"Name": "AA to Slurry ",
"Path": "klj",
"Links": {
"Source": ""
},
"Items": [
{
"Timestamp": "2016-08-21T05:14:27.0180053Z",
"Value": 0.0154830571,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:30Z",
"Value": 0.0155982981,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:30Z",
"Value": 0.0155982981,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:33.024002Z",
"Value": 0.0155704552,
"UnitsAbbreviation": "%",
"Items": [
{
"WebId": "A0EUfSms148rEStZ8_fh",
"Name": “Slurry ",
"Path": "klj",
"Links": {
"Source": ""
},
"Items": [
{
"Timestamp": "2016-08-21T05:14:27.0180053Z",
"Value": 0.0154830571,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:30Z",
"Value": 0.0155982981,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:30Z",
"Value": 0.0155982981,
"UnitsAbbreviation": "%",
"Good": true,
"Questionable": false,
"Substituted": false
},
{
"Timestamp": "2016-08-21T05:14:33.024002Z",
"Value": 0.0155704552,
"UnitsAbbreviation": "%",
这是我迄今为止仅返回名称的代码:
var feat = resp.Items,
tableData = [];
// Iterate over the JSON object
for (var i = 0, len = feat.length; i < len; i++) {
tableData.push({
"name": feat[i].Name,
"Timestamp": feat[i].Timestamp,
"value": feat[i].Items.Value,
});
}
因此，在此示例中，示例表数据理想情况下应如下所示:
name | Timestamp | value
AA to Slurry
AA to Slurry
AA to Slurry
AA to Slurry
AA to Slurry
AA to Slurry
Slurry
Slurry
Slurry
Slurry
Slurry
Slurry
具有第二级“Items”中相应的时间戳和值。现在我得到的只是名称值，如何获取名称然后迭代第二级项目？
最佳答案
我认为你的问题是你的子项目数组被直接访问。 (feat[i].Items.Value) 相反，您也应该循环遍历第二个数组。我将这段代码放在一起让您开始，它循环遍历您拥有的 json 中的项目，然后循环遍历第一个数组的每个项目内的项目。
json.Items.forEach(function(item){
item.Items.forEach(function(subItem){
tableData.push({
'name':item.Name,
'timestamp':item.TimeStamp,
'value':subItem.Value
});
});
});
