    var jsonObj = [{'Id':'1','Quantity':'2','Done':'0','state':'todo',
        'product_id':[315,"[LBI-W-SL-3-AG-TA004-C650-36] LAURA BONELLI-WOMEN'S-SANDAL"],
        'Username':'Ray','FatherName':'Thompson'},  
          {'Id':'2','Quantity':'2','Done':'0','state':'todo',
          'product_id':[314,"[LBI-W-SL-3-AG-TA004-C650-36] LAURA BONELLI-WOMEN'S-SANDAL"],
          'Username':'Steve','FatherName':'Johnson'},
          {'Id':'3','Quantity':'2','Done':'0','state':'todo',
          'product_id':[316,"[LBI-W-SL-3-AG-TA004-C650-36] LAURA BONELLI-WOMEN'S-SANDAL"],
          'Username':'Albert','FatherName':'Einstein'}];

          for (var i = 0; i < jsonObj.length; ++i) {
            if (jsonObj[i]['product_id'][0] === 314) {


                this.onemorecartonsamenumber();


                jsonObj[i]['Done'] = ""+this.quantity_done+"";

                if(jsonObj[i]['Quantity'] === jsonObj[i]['Done']){
                  console.log('both are equal');
                  jsonObj[i]['state'] = 'packed';
                }else{
                  console.log('not equal');
                  jsonObj[i]['state'] = 'todo';
                }

                console.log('quantiy',jsonObj[i]['Quantity']);
                console.log('done',jsonObj[i]['Done']);


            }
        }

        console.log('final',jsonObj);
}

quantity_done: any = 0;

  onemorecartonsamenumber() {
    this.quantity_done += 1;
    console.log(this.quantity_done + 1);
  }
