bootstrap datepicker today as default

I am using this bootstrap-datepicker for my datepicker. I'd like the datepicker to choose "today" for start day or default day. I cannot figure out how to set "today" automatically, so I did an inefficient way

HTML:

<input type="text" value ="today();" id="datepicker"/>

JS:

 $('#datepicker').datepicker();
function today(){
    var d = new Date();
    var curr_date = d.getDate();
    var curr_month = d.getMonth() + 1;
    var curr_year = d.getFullYear();
    document.write(curr_date + "-" + curr_month + "-" + curr_year);
}

Just looking for an easy solution to make the default day as "TODAY".

Thanks

This should work:

$("#datepicker").datepicker("setDate", new Date());

And for autoclose (fiddle):

$('#datepicker').datepicker({
        "setDate": new Date(),
        "autoclose": true
});

jQuery > datepicker API

Set after Init

 $('#dp-ex-3').datepicker({ autoclose: true, language: 'es' });
$('#dp-ex-3').datepicker('update', new Date());

This example is working.

I used this code

$('#datePicker').datepicker({
                    format:'mm/dd/yyyy',
                }).datepicker("setDate",'now');

Date picker with current date and basic settings:

// Datepicker
$('.datepicker').datepicker({
    autoclose: true,
    format: "yyyy-mm-dd",
    immediateUpdates: true,
    todayBtn: true,
    todayHighlight: true
}).datepicker("setDate", "0");

If none of the above option work, use the following :

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

This worked for me.
