jQuery Datatable DOM positioning for Buttons

Question

I just upgraded my jQuery Datatable version to 1.10. And then i tried to remove its retired plugin such as "Colvis" and "Tabletools" with the "Button" extension. Everything works fine here.

But the problem for me is, I could not able to separate "Colvis" button from the "Tabletool" buttons.

"sDom": "B<'row'><'row'<'col-md-6'l><'col-md-6'f>r>t<'row'<'col-md-4'i>><'row'p>B",
    "buttons": [
        'copyHtml5',
        'excelHtml5',
        'csvHtml5',     
        {
            extend: 'colvis',
            postfixButtons: [ 'colvisRestore' ],
            columns: '0,1,2,3,4,5,6'
        }
    ],
    language: {
        buttons: {
            colvis: 'Change columns'
        }
    }

Where in the "sDom", the letter "B" denotes for Buttons. So i am getting all four Buttons (Copy, Excel, CSV and Colvis) in a single row. But i need the "Colvis" button to be separated from (Copy, Excel and CSV).

So Is there any way to add one button near to search box and another one near to the pagination?

OR

Is there any configuration available in the "sDom" or in the "Button"?

Thank you!

Answer 1

You add new elements to the dataTables dom controls by using <'.class'> or <'#id'>. Example, insert a new <div id="colvis"> element to the left of the pagination, <'#colvis'> before p :

"sDom": "B<'row'><'row'<'col-md-6'l><'col-md-6'f>r>t<'row'<'col-md-4'i>><'row'<'#colvis'>p>"

colvis buttons has the class .buttons-colvis, so you move them permanently to the injected #colvis element by :

$('.buttons-colvis').detach().appendTo('#colvis')

This is the fast way to move the colvis button to another location.

Regarding @GreeKatrina's suggestion, yes - but the correct placement method is :

var colvis = new $.fn.dataTable.Buttons( table, {
    buttons: [
        {
            extend: 'colvis',
            ... 
        }
   ]
})
colvis.container().appendTo('#colvis')

if you have a #colvis element of course.

My recommendation : Besides the above hardcoded solution, where you target the colvis buttons specifically, you could monkey patch dataTables buttons so each extended button can have a container option. After initialisation, the button is moved to the specified container :

var org_buildButton = $.fn.DataTable.Buttons.prototype._buildButton;
$.fn.DataTable.Buttons.prototype._buildButton = function(config, collectionButton) {
   var button = org_buildButton.apply(this, arguments);
   $(document).one('init.dt', function(e, settings, json) {
       if (config.container && $(config.container).length) {
          $(button.inserter[0]).detach().appendTo(config.container)
       }
   })    
   return button;
}

use the container option :

{
   extend: 'colvis',
   postfixButtons: [ 'colvisRestore' ],
   container : '#colvis', //<---
   columns: '0,1,2,3,4,5'
}

As the example demonstrates, you can now specify an alternative container for each and every button. Note that container can be any element, it does not have to be an element injected by dom. Also note (as you may notice in the fiddle) that you need to do some styling if you want to make injected elements flow properly along with the native control elements, such as the pagination block.
