I have a complex nested json and I want to parse and display the data in html.
My json looks like:
{
"Test Data": [
{
"First Test": {
"Design Name": "testname",
"Output": "1",
"Data Info": [
{
"Test Name": "ft",
"Time": 10,
}
]
}
},
{
"First Test": {
"Design Name": "testname2",
"Output": "1",
"Data Info": [
{
"Test Name": "ft2",
"Time": 10,
}
]
}
},
]
}
This is a subset of my json. How to parse this data and get the array of Design Names
This is valid JSON so you can use JSON.parse()
method. And then you can use map
method to iterate over and get design names like following:
let myData = JSON.parse(response); // response is the JSON that you provided
let designNames = myData['Test Data'].map(data => data['"First Test"']['Design Name']);
Hope this helps
If your JSON keys does not have spaces:
{
"rootElement": {
"firstElem": "Some data",
"secondElem": {
"thirdLevelElem": "Yet some other data"
}
}
}
You can do this:
const myJsonData = JSON.parse(response);
let firstElement = myJsonData?.rootElement?.firstElem;
let nestdElement = myJsonData?.rootElement?.secondElem?.thirdLevelElem;
DEMO
let myData = { "Test Data": [ { "First Test": { "Design Name": "testname", "Output": "1", "Data Info": [ { "Test Name": "ft", "Time": 10 } ] } }, { "First Test": { "Design Name": "testname2", "Output": "1", "Data Info": [ { "Test Name": "ft2", "Time": 10 } ] } } ] }; var result = myData['Test Data'].map(data => data["First Test"]['Design Name']); console.log(result);
I have the same complex nested json too and I want to parse and display the data in html.
My json looks like:
{
"text": "Apple",
"userName": "Alex",
"dtoList": [
{
"text": "Banana",
"userName": "Sam",
"dtoList": [
{
"text": "Mango",
"userName": "Alex",
"dtoList": [],
},
],
},
{
"text": "Kiwi",
"userName": "Clover",
"dtoList": [
{
"text": "Carrots",
"userName": "Alex",
"dtoList": [],
},
],
},
{
"text": "Beef",
"userName": "Adam",
"dtoList": [],
},
],
},
{
"text": "Egg",
"userName": "Adam",
dtoList: [
{
"text": "Broccoli",
"userName": "Alex",
"dtoList": [],
},
{
"text": "Pumpkin",
"userName": "Sam",
"dtoList": [
{
"text": "Brussels sprouts",
"userName": "Adam",
"dtoList": [],
},
{
"text": "Fruit loops",
"userName": "Clover",
"dtoList": [],
},
],
},
],
},
