Bootstrap datetimepicker / date picker not displaying calendar. Cannot pick a date

Question

I'm trying to get bootstrap datetimepicker to work in conjunction with Datatables so that it filters the datatable when a date is picked. Problem is, it just shows up as an input bar on my page, there is no calendar or calendar symbol. It sounds like a CDN/library reference issue but I've double checked and seem to have them all loaded:

. Jquery . moment.js . Bootstrap . bootstrap-datetimepicker.min.js . bootstrap-datetimepicker.min.css

I've made sure Moment is loaded before bootstrap and jquery. I believe that is all the references I need?Any help would be much appreciated. Thanks

Answer 1

To answer my own question, datetimepicker is not compatible with bootstrap 4

Answer 2

I'd be interested to see what your console is doing but I don't think you want to be repeatedly pushing a function, rather invoking it on change...

I got it working and there were issues with comparing moment Dates with vanilla Dates:

var table = $('#example').DataTable();
var from = null;
var to = null;

$('#from').datetimepicker({
    format: 'DD MMMM YYYY',
    extraFormats: ['DD MM YYYY', 'DD.MM.YYYY',
        'DD/MM/YYYY', 'DD MMM YYYY', 'DD.MMM.YYYY', 'DD/MMM/YYYY', 'DD MMMM YYYY',
        'DD.MMMM.YYYY', 'DD/MMMM/YYYY'
    ]
}).on('dp.change', function(e) {
    from = e.date;
    table.draw();
});

$('#to').datetimepicker({
    format: 'DD MMMM YYYY',
    extraFormats: ['DD MM YYYY', 'DD.MM.YYYY',
        'DD/MM/YYYY', 'DD MMM YYYY', 'DD.MMM.YYYY', 'DD/MMM/YYYY', 'DD MMMM YYYY',
        'DD.MMMM.YYYY', 'DD/MMMM/YYYY'
    ]
}).on('dp.change', function(e) {
    to = e.date;
    table.draw();
});

$.fn.dataTable.ext.search.push(
    function(settings, data, dataIndex) {
        //data being searched
        var startDate = moment(data[2], "DD/MM/YYYY");
        if (!from && !to) {
            return true;
        }
        if (!from && startDate.isSameOrBefore(to, "day")) {
            return true;
        }
        if (!to && startDate.isSameOrAfter(from, "day")) {
            return true;
        }
        if (startDate.isSameOrBefore(to, "day") && startDate.isSameOrAfter(from, "day")) {
            return true;
        }
        return false;
    }
);

Working JSFiddle here.

Hope that helps.
