How to dynamically change jQuery Datatables height

Question

I\'m using jQuery Datatables. I want to change the height of the table whenever a user resizes the window. I\'m able to catch the window resize event which allows me to calculat

Answer 1

Using newer versions of Datatables, there's other methods, which, when combined with the judicious use of a timer for watching the resize event triggers, works pretty well. I've left the "ancient" "window.location.reload()" line in for those who are stuck running older versions of DataTables - simply uncomment it and comment out the "table.draw()" call.

Side note, the documentation says the correct call is "table.Draw()" - that is not the case on the version I am using (call is all lowercase).

$(window).on('resize', function(e) 
{
  if (typeof resizeTimer !== 'undefined') {
    clearTimeout(resizeTimer);
  }
  resizeTimer = setTimeout(function() 
  { 

    // Get table context (change "TABLENAME" as required)
       var table = $('#TABLENAME').DataTable();                                 

    // Set new size to height -100px
       $('.dataTables_scrollBody').css('height', window.innerHeight-100+"px");      

    // Force table redraw
       table.draw();        

    // Only necessary for ancient versions of DataTables - use INSTEAD of table.draw()
       // window.location.reload();
  }, 250);    // Timer value for checking resize event start/stop
});

That's it.

Answer 2

Here is a simple solution as documented here

    $(document).ready(function() {
        $('#example').DataTable( {
            scrollY:        '50vh',
            scrollCollapse: true,
            paging:         false
        });
    });

vh Relative to 1% of the height of the viewport*

You can use the vh unit to set a height that varies based on the size of the window.
