How to dynamically create bootstrap datepicker?

问题

I need to create a date picker dynamically using jQuery. In my form I will have button to create date picker.

Below is the code I tried so far:

<div id="examDatesContainer">
    <div class="form-group">
        <label for="examDate" class="col-sm-2 caption">
            <fmt:message key="exam.date"/>:<strong style="font-size:14px;" class="asterisk">*</strong>
        </label>
        <div class="col-sm-4">
            <div class="input-group date">
                <input type="datetime" class="form-control examDate" id="examDate" name="examDate" value="" readonly >
                <div class="input-group-addon" class="examDateCalendarIcon">
                    <i class="fa fa-calendar"></i>
                </div>
            </div>
            <div class="help-block with-errors"></div>
        </div>
    </div>

    <div class="form-group examDateTemplate" style="display: none;">
        <label for="examDate" class="col-sm-2 caption"></label>
        <div class="col-sm-4">
            <div class="input-group date">
                <input type="datetime" class="form-control examDate" name="examDate" value="" readonly >
                <div class="input-group-addon" class="examDateCalendarIcon">
                    <i class="fa fa-calendar"></i>
                </div>
                <div class="input-group-addon">
                    <i class="fa fa-minus-circle"></i>
                </div>
            </div>
        </div>
    </div>

</div>

<div class="form-group">
    <label for="examDate" class="col-sm-2 caption">
    </label>
    <div class="col-sm-4">
        <button id="addExamDateBtn" type="button" class="btn btn-sm btn-primary">
            <span class="fa fa-plus"> &nbsp;</span>
            <fmt:message key="add"/>
        </button>
    </div>
</div>

and the JavaScript code is as below:

$("#addExamDateBtn").click(function(){
    var examDateClonedObj = $(".examDateTemplate").clone();
    $(examDateClonedObj).removeClass("examDateTemplate");
    $(examDateClonedObj).appendTo("#examDatesContainer");
    $(examDateClonedObj).show();
    $('.datepicker').datetimepicker('update');
});

$('.examDate').datetimepicker({
    format: 'DD/MM/YYYY',
    ignoreReadonly: true,
    showTodayButton: true
});

Basically I show a single datepicker initially. Then I have a button to add more date pickers. Template for datepicker is hidden, on click of "add more" button I just clone it and add it to the DOM.

回答1:

Use this code below

$('body').on('focus',".examDate", function(){
  $(this).datetimepicker({
   format: 'DD/MM/YYYY',
   ignoreReadonly: true,
   showTodayButton: true
 });
});

This way the dynamically created elements can also initialize the datetimepicker.

A working example is posted : Jsfiddle

回答2:

    $('body').on('DOMNodeInserted', function (e) {
        if (e.target.classList.contains('datepicker-container')) {
            $('.datepicker').datepicker({
                format: 'DD/MM/YYYY',
                ignoreReadonly: true,
                showTodayButton: true
            });
        }
    })

Every time a datepicker-container (which obviously contains a datepicker) is added to the DOM, datepickers are initialized. This is how I solved this problem, hope this will help some in the future.
