jQuery change date from format to another one

问题

I have an input text with id CldrFrom

It has date like this: 04/17/2014 in other words mm/dd/yyyy

I want to change it to this format 17-04-2014 in other words dd-mm-yyyy

I want to do that in jQuery.

What I have tried

var currentDate = $(#CldrFrom").val();
val = val.replace("/", "-");

So I replaced the / with - but I still need to make the day as the first not the month. how please?

Edit

to take the date I am using a datepicker library. I call it like this:

$("#CldrFrom, #CldrTo").datepicker();

is there anyway so directly I make that library prints dates in this format dd-mm-yyyy ?

回答1:

Just split and join it together in the order you want

var currentDate = $("#CldrFrom").val();
var dateArr     = currentDate.split('/');
var val         = dateArr[1] + '-' + dateArr[0]  + '-' + dateArr[2];

FIDDLE

回答2:

You can provide a simple regex to .replace() method:

var currentDate = $("#CldrFrom").val(),
    val         = currentDate.replace(/\//g , "-");
