var datas = [];
for(const obj of jsonData){
   labels.push(obj.type);
   datas.push(obj.num);
}

and this is the javascript

Answer 1

Use map :

 const array = [{ type: "العدد الكلي", num: 14 }, //.snip ] const type = array.map(i => i['type']) console.log(type) const num = array.map(i => i['num']) console.log(num)

Answer 2

Just loop over the array of objects.

 var arr = [ {type: "العدد الكلي", num: 14}, {type: "عدد الطلاب", num: 8}, {type: "عدد الأساتذة", num: 2}, {type: "عدد المدراء", num: 1}, {type: "عدد مراقبي الدوام", num: 1}, {type: "عدد مراقبي الحافلات", num: 1}, {type: "عدد مراقبي الرسوم", num: 1} ]; var labels = []; var datas = []; for(const obj of arr){ labels.push(obj.type); datas.push(obj.num); } console.log("Labels", labels); console.log("Datas", datas);

For your particular case, you need to be looping over the array in the callback for the AJAX call, as AJAX is asynchronous.

$.get('../Functions/Ajax/GetSortingData.php?id='+schoolId, function(data){
            jsonData = JSON.parse(data);
            console.log(jsonData);
            var labels = [];
            var datas = [];
            for(const obj of jsonData){
               labels.push(obj.type);
               datas.push(obj.num);
            }
            console.log(datas);
       });
