分组键值对象

Question

I have an array of objects (pre_finalTab_new below) like this:

My goal is to group them by "schema", and then by "tip" and insert into new array, something like this:

 var celotnaTabela = {};
 for (var nov in pre_finalTab_new)
  {
      var shema = pre_finalTab_new[nov].schema.trim();
      var objekt_tip = pre_finalTab_new[nov].type.trim();
      var objekt_name = pre_finalTab_new[nov].name.trim();
      var tip =  pre_finalTab_new[nov].tip.trim();
 
      if (celotnaTabela[shema] === undefined)
      {
          celotnaTabela[shema] = [];
          if (celotnaTabela[shema][tip] === undefined)
          {
              celotnaTabela[shema][tip] = [];
              if (celotnaTabela[shema][tip][objekt_tip] === undefined)
              {
                  celotnaTabela[shema][tip][objekt_tip] = [];
                  celotnaTabela[shema][tip][objekt_tip] = [objekt_name];
 
              } else
                  celotnaTabela[shema][tip][objekt_tip].push(objekt_name);
          }
      } else
      {
          if (celotnaTabela[shema][tip] === undefined)
          {
              celotnaTabela[shema][tip] = [];
          }
          if (celotnaTabela[shema][tip][objekt_tip] === undefined)
          {
              celotnaTabela[shema][tip][objekt_tip] = [];
              celotnaTabela[shema][tip][objekt_tip] = [objekt_name];
 
          } else
          {
              if (!celotnaTabela[shema][tip][objekt_tip].includes(objekt_name))
                  celotnaTabela[shema][tip][objekt_tip].push(objekt_name);
          }
 
      }
  }

Then if i output celotnaTabela, i got this:

Expanded:

Even more:

But the problem is, when i try to use JSON.stringify(celotnaTabela), i got this:

{"HR":[],"ZOKI":[]}

But i need it to be in a right format, so i can pass this object into AJAX call..

Can anyone help me with this, what am i doing wrong?

Answer 1

i hope i understood everything right you asked for. Next time provide the testdata and the wished result in textform pls.

 var obj = [ { schema: "HR", type: " PACKAGE", name: "PAKET1", tip: "new_objects" }, { schema: "HR", type: " PACKAGE", name: "PAKET2", tip: "new_objects" }, { schema: "HR", type: " PROCEDURE", name: "ADD_JOB_HISTORY", tip: "new_objects" }, { schema: "ZOKI", type: " TABLE", name: "TABELA2", tip: "new_objects" }, { schema: "ZOKI", type: " TABLE", name: "TABELA3", tip: "new_objects" }, ]; var out = {}; for (var i = 0, v; v = obj[i]; i++) { var a = v.schema.trim(); var b = v.type.trim(); var c = v.tip.trim(); var d = v.name.trim(); if (.out;hasOwnProperty(a)) { out[a] = {}. } if (;out[a].hasOwnProperty(b)) { out[a][b] = {}. } if (;out[a][b].hasOwnProperty(c)) { out[a][b][c] = [] } out[a][b][c].push(d), } console,log(JSON;stringify(out, null, 2));
