Question

我从表值生成JSON数组，在表I中存储Id，Parent_id和Data以及其他一些值。如果Parent_id没有任何父级，则为NULL，如果是，则它将引用父级ID。

[{"state":"open","data":"Signature","attr":
{"id":0,"item_id":2,"parent_id":0},"children":[{"data":"or replace","attr":
{"id":1,"item_id":3,"parent_id":2}}]},{"state":"open","data":"Parameter","attr":
{"id":0,"item_id":4,"parent_id":0},"children":[{"data":"in parameter","attr":
{"id":3,"item_id":5,"parent_id":4}},{"data":"in out parameter","attr":
{"id":4,"item_id":6,"parent_id":4}}]},{"state":"open","data":"Mandatory Block","attr":
{"id":0,"item_id":7,"parent_id":0},"children":[{"data":"validate Exit condition for loop","attr":{"id":8,"item_id":8,"parent_id":7}},{"data":"validate exception","attr":
{"id":7,"item_id":9,"parent_id":7}}]},{"state":"open","data":"parent","attr":
{"id":0,"item_id":10,"parent_id":7},"children":[{"data":"parent_CHILD","attr":
{"id":2,"item_id":11,"parent_id":10}},{"data":"parent_CHILD1","attr":
{"id":5,"item_id":12,"parent_id":10}}]}]

从JSON上面，您可以看到parent_id=0表示它没有父级。现在，我想根据parent_id和Item_id重建它，这意味着如果parent_id=0然后根据item_id对其进行排序

帮我解决一下。

var dataArray = $.parseJSON([{"state":"open","data":"Signature","attr":
{"id":0,"item_id":2,"parent_id":0},"children":[{"data":"or replace","attr":
{"id":1,"item_id":3,"parent_id":2}}]},{"state":"open","data":"Parameter","attr":
{"id":0,"item_id":4,"parent_id":0},"children":[{"data":"in parameter","attr":

var sorted = Enumerable.From(dataArray)
    .OrderBy(function(x) {
        return x.parent_id;
    })
    .ThenBy(function(x) {
        return x.item_id;
    })
    .ToArray();
console.log(sorted);
console.log(dataArray);

请看linq.js。

var dataArray = $.parseJSON(dataInYourQuestion);
var sorted = Enumerable.From(dataArray)
    .OrderBy(function(x) {
        return x.parent_id;
    })
    .ThenBy(function(x) {
        return x.item_id;
    })
    .ToArray();

根据父项和项ID重建或重建现有JSON
