How to dynamically set bootstrap-datepicker's date value?

Question

I am using bootstrap datepicker along with a line highchart.

I want the datepicker date to update when the chart is zoomed. Once that event triggers I update the values of the datepicker. The values update fine but when the calendar is clicked, the date on the popup calendar is still the old date.

Here is my datepicker:

<div class="input-append date pull-right" id="dpStartDate" data-date="@DateTime.Now.AddMonths(-1).ToString("dd/MM/yyyy")" data-date-format="dd/mm/yyyy">     <input class="span2" id="startDateText" size="16" type="text" value="@DateTime.Now.AddMonths(-1).ToString("dd/MM/yyyy")" readonly="">     <span class="add-on"><i class="icon-th"></i></span> </div> 

I have tried just updating the values using this code:

$('#dpStartDate').attr('data-date', startDate); $('#startDateText').attr('value', startDate); 

which updates the dates fine but doesn't set the calendar.

I've also tried triggering the onChange event, which also updates the dates but not the calendar:

$('#dpStartDate').trigger('changeDate', startDate);  $('#dpStartDate').datepicker()     .on('show', function (ev) {         ev.stopPropagation();     })     .on('changeDate', function (ev, date) {         var startDate = new Date();         if (date != undefined) {             startDate = date;             $('#dpStartDate').attr('data-date', startDate);             $('#startDateText').attr('value', startDate);         }         else {             startDate = ev.date;             $('#dpStartDate').attr(startDate.getDate() + '/' + (startDate.getMonth() + 1) + '/' + startDate.getFullYear());             $('#startDateText').attr(startDate.getDate() + '/' + (startDate.getMonth() + 1) + '/' + startDate.getFullYear());         }         $('#dpStartDate').datepicker('hide');         ev.stopPropagation();     }); 

Does anyone know if it's even possible to update the calendar like that?

Thanks

Answer 1

This works for me

$(".datepicker").datepicker("update", new Date()); 

Answer 2

var startDate = new Date();  $('#dpStartDate').data({date: startDate}).datepicker('update').children("input").val(startDate); 

another way

$('#dpStartDate').data({date: '2012-08-08'}); $('#dpStartDate').datepicker('update'); $('#dpStartDate').datepicker().children('input').val('2012-08-08'); 

1. set the calendar date on property data-date
2. update (required)
3. set the input value (remember the input is child of datepicker).

this way you are setting the date to '2012-08-08'
