Bootstrap datepicker — how to get date as a string in the right format?

问题

I'm using Bootstrap datepicker. The answer is probably obvious, but I can't figure out how to get the selected date as a string in the specified format. I used:

<div id="myDate" data-date-format="yyyy-mm-dd">
  <input type="text">
</div>

And in my javascript:

var value = $("#myDate").datepicker("getDate");

But it returns a date, not a string in yyyy-mm-dd format.

回答1:

The data-date-format="mm/dd/yyyy" needs to be set on the input:

<input type="text" data-date-format="MM/DD/YYYY">

Your jQuery should also be changed to:

var value = $("#myDate input").datepicker("getDate");

Or you can just keep things simple with no wrapping div and with this your original jQuery would work fine and you wouldn't have to specify input:

<input type="text" id="myDate" data-date-format="YYYY-MM-DD">

Suggestion
I would recommend creating a class to format the datepicker. So that you can then add the .datepicker class to any input field and it would work without having to specify another variable.

回答2:

var value = $("#myDate").datepicker("getFormattedDate");

回答3:

If you want the value as a string use: var value = $("#myDate input").val();

The method getDate returns an object
