Default value to a Datatable editor field, from a javascript function

jalape

Hello,
I want to pass a default value to a Datatable editor field, from a javascript function that generates a random code.

function makeid(length) {
   var result           = '';
   var characters       = 'abcdefghijklmnopqrstuvwxyz0123456789';
   var charactersLength = characters.length;
   for ( var i = 0; i < length; i++ ) {
      result += characters.charAt(Math.floor(Math.random() * charactersLength));
   }
   return result;

}

I don't know how the function is referenced in the edit form field.

            {
                label: "code:",
                name:  "sml_maps.code",
                default: ''
            },

Thanks

You can use fields.def for that - see the name field here: http://live.datatables.net/gadayoke/1/edit

Thanks Colin for answering.
The "def" name field for the editor is clear. What I don't know is how I can pass a javascript makeid function.

fields.def can be a function - see here: http://live.datatables.net/gadayoke/2/edit

The only downside is that the length can't be passed in, so that will either need to be a constant or a value you pull from elsewhere.

In my case a constant is enough.
Thank you very much.
