       Hello Fred,

      i have a json object like this :

      let myObject := 

        {
    myObject : {
      paul : '10',
      jack : '20',
      bob  : '30'
    }
  };

      And i need to iterate on every key/value.

      I thinking the json object ca be used like : item(myObject, i ) for the key value.

      I look in the documentation : 

      https://docs.ninox.com/en/print/print-customization/repetitions/iterate-over-objects

      we can use : {d.myObject[i].att} to get the attribute and {d.myObject[i].val} to get the value of this attribue or key.

      But cant understant how you can use this.

          Hi, according to the Ninox documentation you can use the item() function with a json object like below:  

      let data := {
    firstName: "Steve",
    lastName: "Rogers"
    };
item(data, "firstName")

       Yes thank you for the information, but in documentation is mentionned: 
       

       

      Syntax

      item([any], number)

      item(JSON, number)

      item(JSON, string)

       

      and the second is : item(JSON, number) and i dont know to use that version : item(JSON, number)

      Just to clairfy, are you trying to use JSON in a formula or in a dynamic print page? I ask because your first post refers to dynamic printing. Then posts the item() command which is used in Ninox formula fields.

        item(myJSON, key) To extract the value of a key-value pair of a given JSON object. The key might be a string or a number. 
      I think you can not iterate a json object using item function because the number refers to key, it’s not an index

    in relation with this part of documentation:
    https://docs.ninox.com/en/print/print-customization/repetitions/iterate-over-objects

    it is important part of my code this section of documentation.
    ------

     

    I need to create a function for logging.
    i have a object : let myObject:=

     {
    myObject : {
      paul : '10',
      jack : '20',
      bob  : '30'
    }
  }


    i create a function :
    function createLog(object:any) do
           let mylog:="";
           let sep:="|";
           for i in range(0,cnt(object.log)) do
                  log:=log+"
                         "+ DateTime+sep+object.log[i].att+object.log[i].val+.......
           end;

    end

     

    Yes i can send a array, but i want play with json object.

      You are mixing up commands from the dynamic print engine and regular Ninox commands.

      You wrote:

      function createLog(object:any) do
       let mylog:="";
       let sep:="|";
       for i in range(0,cnt(object.log)) do
              log:=log+"
                     "+ DateTime+sep+object.log[i].att+object.log[i].val+.......
       end;
end

      so on line 6 you are using [i], which is dynamic printing code. Well to be more specific it is what Carbone uses to do their dynamic printing. You can't use this in regular Ninox commands.

      Question: what is the log field? a reference field? a formula field? another type?

     is the code below what are you looking for?

    let Data := {
        myObject: [{
                paul: "10"
            }, {
                jack: "20"
            }, {
                bob: "30"
            }]
    };
join(for i in Data.myObject do
    text(Data.myObject.i)
end, ",")

    the above inside a function field results in:

    {"paul":"10"},{"jack":"20"},{"bob":"30"}

    You can also use this code to get a list of your Json:

    let myobject := {
        myObject: {
            paul: 10,
            jack: 20,
            bob: 30
        }
    };
for name, value in myobject.myObject do
    name + ":" + value
end

    The result of this is:

    paul:10,jack:20,bob:30

        great! I've learned something new today!

      So, we can loop inside a json object if we declare two labels (variables) one for the "name" and the other for the "value" in the "name/value" pairs.

      Is my understanding correct?
