Make eternicode datepicker open on click, not focus

问题

The eternicode twitter bootstrap datepicker pops up as soon as the <input> field it is attached to gets focus, as you can see by tabbing onto the datepicker field on the official demo page.

Instead, I want it to only open on click. Ideally the datepicker would just pop up on click of the calendar icon.

How can I prevent it from popping up on focus?

In the current version of the library, there's no official support for what you want to do. The docs list all the kinds of markup you can instantiate a datepicker on and what the resulting behaviours are. It's very clear that when instantiating a datepicker on an <input> element,

focusing the input (clicking or tabbing into it) will show the picker.

There is no markup you can instantiate a datepicker on that will trivially give you what you want. Nor are there any configuration options that let you choose what events will trigger the datepicker to appear.

As a result, to do what you want will require some reverse engineering of the library. Luckily, this is quite easy.

The simplest approach is to instantiate the datepicker on the <input> like you normally would, but then get rid of the focus handler ourselves and replace it with a click handler:

$('#my-input').datepicker()
              .off('focus')
              .click(function () {
                  $(this).datepicker('show');
              });

This works perfectly for the latest version of the library, as demonstrated by this http://jsfiddle.net/E4K56/1/

If you want to have extra elements (like a calendar button) that trigger the appearance of the datepicker, you can just attach handlers to them similarly:

$('#some-button').click(function () {
    $('#my-input').datepicker('show');
});

I have the same notation as in demo:

<label for="datepickerFrom" class="control-label input-group">Set the date from:</label>
<div class="form-group">
    <div class='input-group date' id='datepickerFrom'>
        <input type='text' class="form-control" />
        <span class="input-group-addon">
            <span class="glyphicon glyphicon-calendar"></span>
        </span>
    </div>
</div>

And then add add the event on input click:

var options = {
    language: 'cs'
}
$('#datepickerFrom').datetimepicker(options);
$('#datepickerFrom input').off('focus')
    .click(function () {
        $(this).parent().data("DateTimePicker").show();
    })
