Q:

How do I set default settings for Datetimepicker? 

I have multiple calendar inputs set up with Bootstrap Datetimepicker: http://eonasdan.github.io/bootstrap-datetimepicker/.
I have created an object containing some overwrites: 
DatetimepickerDefaults = {
    icons: {
        time: 'fa fa-clock-o',
        date: 'fa fa-calendar',
        up: ' fa fa-angle-up',
        down: 'fa fa-angle-down',
        previous: 'fa fa-angle-left',
        next: 'fa fa-angle-right',
        today: 'fa fa-crosshairs',
        clear: 'fa fa-trash',
        close: 'fa fa-times'
    }
}

that I want to apply to all of the calendar inputs.  So now when I want to init a plugin I write: 
$('#datetimepicker1').datetimepicker(DatetimepickerDefaults);

The problem is that some of the inputs need to have some special settings, like format: 'LT' so when I init them, I write:
$('#datetimepicker3').datetimepicker({
    icons: {
        time: 'fa fa-clock-o',
        date: 'fa fa-calendar',
        up: ' fa fa-angle-up',
        down: 'fa fa-angle-down',
        previous: 'fa fa-angle-left',
        next: 'fa fa-angle-right',
        today: 'fa fa-crosshairs',
        clear: 'fa fa-trash',
        close: 'fa fa-times'
    },
    format: 'LT'
});

so I have to repeat this default settings all over again.  Is there any way to make it default for all of the plugin instances? 

A:

You can set it as a function like:
function. DatetimepickerDefaults = function(field, value) {
    var retVal = {
    icons: {
        time: 'fa fa-clock-o',
        date: 'fa fa-calendar',
        up: ' fa fa-angle-up',
        down: 'fa fa-angle-down',
        previous: 'fa fa-angle-left',
        next: 'fa fa-angle-right',
        today: 'fa fa-crosshairs',
        clear: 'fa fa-trash',
        close: 'fa fa-times'
    }};
    if (field) {
        retVal[field] = value;
    }
    return retVal;
}

And use it like:
$('#datetimepicker1').datetimepicker(DatetimepickerDefaults());
$('#datetimepicker2').datetimepicker(DatetimepickerDefaults("format", "LT"));
$('#datetimepicker2').datetimepicker(DatetimepickerDefaults("format", "LT2"));
//And etc...

You can use lists for more values, I hope this helps
