Wenn ich folgende Daten habe, wie folgt:
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);
Ich habe separate Ajax-Aufrufe für diechildrenEigenschaft jedes übergeordneten Elements und sie geben ein Array zurück. Ist es möglich, diese drei Arrays zu kombinieren, um ein Array wie das in der Geige gezeigte zu erzeugen?
Die Originalquelle der oben genannten Daten ist hier und wurde von hier bezogen
Weitere Erklärungen, die ich möchte:
Ich habe 3 Arrays zur Hand.
"EmployeeID": 2,Daten."EmployeeID": 8,1,3,4和5, die untergeordnete Elemente des ersten Arrays sind."EmployeeID": 6,7和9, die Kinder des zweiten Arrays sind.Ich habe alle oben genannten Arrays (oben nicht gezeigt) über Ajax-Aufrufe erhalten und habe mich gefragt, ob ich sie auf diese Weise kombinieren könnte, um Daten im oben genannten Format zu generieren. Was mich verwirrt, ist, wie manchildren:
wie im obigen Format hinzufügt.
在这里你可以尝试这个逻辑：
我们可以传递具有嵌套结构的数据，例如：
data->childrenArray->data->childrenArray等等在MakeNestedInLinear(data)中，它将返回单个数组（线性数据）中的扁平结果
