Nested Json

al_1976

Hi

Excuse the newbie question but its driving me up the wall and any help would be much appreciated. I have a nested JSON object called activity. If this has values I want to display them (ideally wrapped in html). If they are no values I just want to display some default text.

Hopefully this simple example will make it clear http://live.datatables.net/radabaye/1/

Many thanks

activity is an array so you would need to use array syntax ("activity[].timestamp" for example) - see column.data for more information about this. Or use column.render if you want to format them with some HTML.

That's great thanks for your help. I'm still have a little trouble getting my head around it . I have updated the link to my latest work. What I really what to do is take the data in activity array and create another table from it within the current cell, is that possible?

Thanks again for you time I really appreciate it

You are going to need to explain that a bit further for me please. Do you simply want the data in the array shown in a <table> inside the DataTable cell?

You could use columns.render to produce the HTML needed for that table if so.

Hi Allan

That's exactly what I want to do. If the activity array has data I want to create a table using that data inside the DataTable cell. I have looked at columns.render but I can't seem to get it to work. No errors it just doesn't display anything.

Could I be really cheeky and ask for some example to code to push me in the right direction please? I must be doing something stupid

Many Thanks

Something like:

{
  data: 'activity',
  render: function ( data, type, row ) {
    // `data` is the `activity` array!
    var s = '';

    for ( var i=0, ien=data.length ; i<ien ; i++ ) {
      s += data[i].timestamp+' ';
    }

    return s;
  }
}

It isn't a table I know - but hopefully you can fill in the blanks using the above :-)
