jquery – Is it possible to add a function in a json?

Question:

Let's get to the problem. In datatable.js, to display the columns I define it as follows:

    "aoColumns": [
                { "mDataProp": "IdProcesso", "sTitle": "Numero" }
                 ]

If you need to perform any function:

                 {
                    "mDataProp": "DataAbertura", "sTitle": "Data Abertura",
                    "fnRender": function (oObj) {
                        return //minha function vem aqui!
                    }
                },

Now comes the question, is it possible for me to add this function to the Json object dynamically? When I say dynamic I mean the fact that this object will be created by another function and at the end it returns a string generated by JSON.stringify and the function is unusable. I hope I managed to explain my doubt

Answer:

There is an alternative, using the eval function.

The eval function executes the string passed to it, as you can see in the example below:

eval('alert("teste")');

This will make the alert appear on the screen. So my suggestion is that you save your function in string format, and run it like that.
