kendo ui Data Source - Schema - Parse function error when creating new Function inside

Question

I am using the following constructor create a new function: new Function("args", body);

but in parse function it throwing the following error:

Uncaught SyntaxError: Unexpected identifierkendo.data.DataSource.schema.parse @ KendoWorklist?processId=1:257g.extend.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1g.extend.read.i._queueRequest.i.online.i.transport.read.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1vt.extend.read.i.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1i.Callbacks.a @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1i.Callbacks.h.fireWith @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1k @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1i.ajaxTransport.send.u @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1

why would the new Function constructor not working in the parse function?

I'm lost with the question, what are you trying to do? can you give us more details — cycopepe

@cycopepe I'm trying to create a new function in the parse method like.... parse: function(response){ var x = new Function("args", body)} — T. Holland

@cycopepe stackoverflow.com/questions/31707085/… look at my answer to this question. I'm parsing normalized data to become denormalized. — T. Holland

If make the model outside the parse function of the schema, you can use it like this

   <script>
      var fields = ["fieldA","fieldB"];
      var body = "";

    for(var i = 0; i < fields.length; i++){
       body += "this."+fields[i] +"=args["+i+"]; ";
    }
      var model = new Function("args",body);

    var dataSource = new kendo.data.DataSource({
      transport: {
        read: {
          url: "", //your url
          dataType: "jsonp"
        }
      },
      schema: {
        parse: function(response) {  
         var parsedresponse = [];    
          for (var i = 0; i < response.length; i++) {
             var x = new model(response[i]);   
             parsedresponse .push(prxduct);
          }

          return parsedresponse;
        }
      }
    });

    </script>

thank you! but I get the fields from the response object. I would have to call the data twice. I want to avoid it if possible but it may be the only way I'm really stumped.

actually I think I will just get the fields in a separate request like your answer suggests... the request will be small because I don't need any rows.
