bootstrap modal and datepicker show events

问题:

When click on datepicker (http://www.eyecon.ro/bootstrap-datepicker/), his SHOW event fires, but the modal's SHOW.BS.MODAL fires too. Whhere is a problem?

$(document).ready(function() {
$('#ArrDate')
.datepicker()
.on("show", function(event){
    alert("Q");
});

$("#dlg3000to3100")
.on('show.bs.modal', function (event) {
    alert("W");
});

$("#dlg3000to3100")
.modal("show");
});

exampleExample

Thanks

It seems to be a bug (or feature?) of the datepicker. What you can do is to prevent the show.bs.modal event reaching the dialog.

$('#ArrDate').on('show.bs.modal', function (event) {
    event.stopPropagation();
});

This will detect the event at the datepicker level and stop the event propagation, so show.bs.modal will not 'bubble up' to the dialog.

Another work around is to swap the show.bs.modal with shown.bs.modal on modal event.

modal.on('shown.bs.modal', function (event) {
               // Do something
            });

however if it is not possible to swap show with shown or hide with hidden use the namespace check

modal.on('show.bs.modal', function(e) {
    if (e.namespace === 'bs.modal') {
         // Do something
    }

});

Had a similar issue, caused by the datepicker watching for a show event.

One option is to use the shown event on the modal but this is not ideal in all cases

$('#dlg3000to3100').on('shown.bs.modal', function (event) {
    // modal code in here
});

A more elegant solution is to check the namespace of the event

$('#dlg3000to3100').on('show.bs.modal', function (event) {
    if(event.namespace !== 'bs.modal') return;
    // modal code in here
});
