If I have the following data as follows:
var data = [{ "EmployeeID": 2, "FirstName": "Andrew", "LastName": "Fuller", "Country": "USA", "Title": "副总裁，销售", "HireDate": "1992-08-14 00:00:00", "BirthDate": "1952-02-19 00:00:00", "City": "Tacoma", "Address": "908 W. Capital Way", "expanded": "true", children: [{ "EmployeeID": 8, "FirstName": "Laura", "LastName": "Callahan", "Country": "USA", "Title": "内部销售协调员", "HireDate": "1994-03-05 00:00:00", "BirthDate": "1958-01-09 00:00:00", "City": "Seattle", "Address": "4726 - 11th Ave. N.E." }, { "EmployeeID": 1, "FirstName": "Nancy", "LastName": "Davolio", "Country": "USA", "Title": "销售代表", "HireDate": "1992-05-01 00:00:00", "BirthDate": "1948-12-08 00:00:00", "City": "Seattle", "Address": "507 - 20th Ave. E.Apt. 2A" }, { "EmployeeID": 3, "FirstName": "Janet", "LastName": "Leverling", "Country": "USA", "Title": "销售代表", "HireDate": "1992-04-01 00:00:00", "BirthDate": "1963-08-30 00:00:00", "City": "Kirkland", "Address": "722 Moss Bay Blvd." }, { "EmployeeID": 4, "FirstName": "Margaret", "LastName": "Peacock", "Country": "USA", "Title": "销售代表", "HireDate": "1993-05-03 00:00:00", "BirthDate": "1937-09-19 00:00:00", "City": "Redmond", "Address": "4110 Old Redmond Rd." }, { "EmployeeID": 5, "FirstName": "Steven", "LastName": "Buchanan", "Country": "UK", "Title": "销售经理", "HireDate": "1993-10-17 00:00:00", "BirthDate": "1955-03-04 00:00:00", "City": "London", "Address": "14 Garrett Hill", "expanded": "true", children: [{ "EmployeeID": 6, "FirstName": "Michael", "LastName": "Suyama", "Country": "UK", "Title": "销售代表", "HireDate": "1993-10-17 00:00:00", "BirthDate": "1963-07-02 00:00:00", "City": "London", "Address": "Coventry House Miner Rd." }, { "EmployeeID": 7, "FirstName": "Robert", "LastName": "King", "Country": "UK", "Title": "销售代表", "HireDate": "1994-01-02 00:00:00", "BirthDate": "1960-05-29 00:00:00", "City": "London", "Address": "Edgeham Hollow Winchester Way" }, { "EmployeeID": 9, "FirstName": "Anne", "LastName": "Dodsworth", "Country": "UK", "Title": "销售代表", "HireDate": "1994-11-15 00:00:00", "BirthDate": "1966-01-27 00:00:00", "City": "London", "Address": "7 Houndstooth Rd." } ] } ] }]; console.log(data);
I have separate Ajax calls for each parent'schildrenproperty and they return an array. Is it possible to combine these three arrays to produce an array like the one shown in the fiddle?
The original source of the above data is here, which is obtained from here
More explanations I want:
I have 3 arrays on hand.
"EmployeeID": 2,."EmployeeID": 8,1,3,4 and 5, which are children of the first array."EmployeeID": 6, 7 and 9, which are children of the second array.I got all the above arrays (not shown above) via Ajax calls and was wondering if I could combine them in this way to produce data in the above format. What confuses me is how to addchildren like in the format above:

Here you can try this logic:
We can pass data with nested structure, for example:
data->childrenArray->data->childrenArray etc.In MakeNestedInLinear(data), it will return the flat results in a single array (linear data)
