用於構建 FancyTree JSON 的遞歸 JavaScript 函數
[英]Recursive JavaScript Function to Build FancyTree JSON
問題描述
我正在嘗試為 FancyTree ( https://github.com/mar10/fancytree/wiki/TutorialLoadData ) 構建 JSON 對象數組。 但是，我的 JSON 源（Jira REST 服務）幾乎可以具有任何結構，因此構建 JSON 對象數組的代碼必須是完全通用的並且能夠處理幾乎任何東西。
以下是源 JSON 的示例：

我需要得到一個如下所示的 JSON 對象數組：
[
{title: "Node 1", key: "1"},
{title: "Folder 2", key: "2", folder: true, children: [
{title: "Node 2.1", key: "3", myOwnAttr: "abc"},
{title: "Node 2.2", key: "4"},
{title: "Folder 3", key: "5", folder: true, children: [
{title: "Node 3.1", key: "6", myOwnAttr: "xyz"},
{title: "Node 3.2", key: "7"}
]}
]}
]
這是我目前的嘗試。 它沒有按預期工作。
const createTreeJson = function(){
let treeJson = [];
let treeJsonObj = {};
//loop entry array, but there is only ever 1
feedJson.feed.entry.forEach((entry) => {
treeJsonObj = {};
//items
treeJsonObj.title = "Item";
treeJsonObj.folder = true;
let children = [];
//loop object properties
Object.entries(entry).forEach(([key, value]) => {
children.push(createTreeJsonObject(children, key, value));
});
treeJsonObj.children = children;
treeJson.push(treeJsonObj);
});
console.log(treeJson);
}
const createTreeJsonObject = function(children, key, value){
console.log(key, value);
if(value.constructor.name === "Object"){
//it's an object
let subChildren = [];
Object.entries(value).forEach(([key2, value2]) => {
subChildren.push(createTreeJsonObject(subChildren, key2, value2));
});
children.push({
"title": key,
"folder": true,
"children": subChildren
});
}else if(value.constructor.name === "Array"){
//it's an array
}else{
//it's something else
children.push({
"key": key,
"title": `${key}`,
"tooltip": `${value}`
});
}
return children;
};
createTreeJson();
注意：代碼中的 feedJson 就是上面的源 JSON。 我不想在代碼中再次重復它。 你也可以在這里的小提琴中看到它： https ://jsfiddle.net/ua8vm9p7/1/
如果它更容易，我願意使用像 loadash 這樣的東西來幫助解決這個問題。 我也有可用的 jQuery，但我試圖遠離它。
我似乎無法完全理解正確的邏輯。 以前有人做過這種事情嗎？ 任何人都可以幫助我如何做到這一點？
謝謝。

我認為更簡單的代碼可以做到這一點：
const makeFancyMenu = (obj) => Object .entries (obj) .flatMap (([k, v]) => Array .isArray (v) ? [] : Object (v) === v ? [{title: k, folder: true, children: makeFancyMenu (v)}] : [{key: k, title: `${k}`, tooltip: v}] ) const convert = (obj) => obj .feed .entry .map ((o) => ({ title: 'Item', folder: true, children: makeFancyMenu (o) })) const input = {feed: {entry: [{expand: "renderedFields,names,schema,operations,editmeta,changelog,versionedRepresentations", id: "95743", self: "foo.comjira/rest/api/2/issue/95743", key: "XYZ-24600", fields: {MandatoryReviewersInternal: [{self: "foo.comjira/rest/api/2/customFieldOption/10947", value: "Test", id: "10947", disabled: !1}],PlannedDropDate: "2022-02-01", assignee: {self: "foo.comjira/rest/api/2/user?username=swchambe", name: "swchambe", key: "swchambe", emailAddress: "sharon.w.chamberlain@foo.com", displayName: "Sharon W Chamberlain", active: !0,timeZone: "America/Chicago"},ESBEnvironments: {self: "foo.comjira/rest/api/2/customFieldOption/10120", value: "All Environments", id: "10120", disabled: !1},RestrictedInformation: "Do not include Proprietary, ITAR or SBU restricted information in this action", subtasks: [{id: "96160", key: "XYZ-24601", self: "foo.comjira/rest/api/2/issue/96160", fields: {summary: "Test 1", status: {self: "foo.comjira/rest/api/2/status/10338", description: "", iconUrl: "foo.comjira/images/icons/statuses/generic.png", name: "Current", id: "10338", statusCategory: {self: "foo.comjira/rest/api/2/statuscategory/4", id: 4,key: "indeterminate", colorName: "yellow", name: "In Progress"}},issuetype: {self: "foo.comjira/rest/api/2/issuetype/10319", id: "10319", description: "", iconUrl: "foo.comjira/secure/viewavatar?size=xsmall&avatarId=11747&avatarType=issuetype", name: "Affected Document", subtask: !0,avatarId: 11747}}},{id: "96466", key: "XYZ-24614", self: "foo.comjira/rest/api/2/issue/96466", fields: {summary: "Test 2", status: {self: "foo.comjira/rest/api/2/status/10338", description: "", iconUrl: "foo.comjira/images/icons/statuses/generic.png", name: "Current", id: "10338", statusCategory: {self: "foo.comjira/rest/api/2/statuscategory/4", id: 4,key: "indeterminate", colorName: "yellow", name: "In Progress"}},issuetype: {self: "foo.comjira/rest/api/2/issuetype/10319", id: "10319", description: "", iconUrl: "foo.comjira/secure/viewavatar?size=xsmall&avatarId=11747&avatarType=issuetype", name: "Affected Document", subtask: !0,avatarId: 11747}}}],Participants: [{name: "djcook2(djcook2xyz)"},{name: "swchambe(swchambexyz)"},{name: "r_slscdm(JIRAxyz)"}],reporter: {self: "foo.comjira/rest/api/2/user?username=djcook2", name: "djcook2", key: "djcook2", emailAddress: "deborah.j.ott@foo.com", displayName: "Deborah Jane Ott", active: !0,timeZone: "America/Chicago"},CPEOrganization: "xyz", SFSearchandViewLink: "<a href=foo.comportal/web/csa/search?key=95743&projectKey=XYZ&issueType=Change%20Request>S2D-0637</a>", progress: {progress: 0,total: 0},issuetype: {self: "foo.comjira/rest/api/2/issuetype/8", id: "8", description: "Request for a change to the way the application works.", iconUrl: "foo.comjira/secure/viewavatar?size=xsmall&avatarId=11737&avatarType=issuetype", name: "Change Request", subtask: !1,avatarId: 11737},project: {self: "foo.comjira/rest/api/2/project/13390", id: "13390", key: "XYZ", name: "Configuration Status Accounting", projectTypeKey: "business"},SFIdentifier: "S2D-0637", watches: {self: "foo.comjira/rest/api/2/issue/XYZ-24600/watchers", watchCount: 2,isWatching: !0},ServerEnvironment: [{self: "foo.comjira/rest/api/2/customFieldOption/10060", value: "Production", id: "10060", disabled: !1}],ScheduleImpact: {self: "foo.comjira/rest/api/2/customFieldOption/12245", value: "No", id: "12245", disabled: !1},MissionConfigurationDefinition: [{self: "foo.comjira/rest/api/2/customFieldOption/12246", value: "1110-1200", id: "12246", disabled: !1},{self: "foo.comjira/rest/api/2/customFieldOption/12247", value: "1110-2200", id: "12247", disabled: !1}],updated: "2022-05-23T10: 06: 45.000-0500", description: "¶ Paragraph\nNonbreaking Hyphen\nEm Space\nEn Space\n½ One Half Fraction\n¼ One Quarter Fraction\n¾ Three Quarters Fraction\n10⁵ superscript\n6⁵ superscript\nO₂ subscript\n\n± 0177\n≤ 2264\n≥ 2265\n\n10⁰ -

在這里， makeFancyMenu完成了所有遞歸的繁重工作，並且convert簡單地將其包裝在處理根差異的東西中。
我們使用flatMap代替map並將其單個回調返回包裝在數組中，以便在數組屬性的情況下，我們可以只返回一個空數組。 這是一種結合filter和map的簡單方法。
