How to get current date in jQuery?

Date() is not part of jQuery, it is one of JavaScript’s features.

See the documentation on Date object.

You can do it like that:

var d = new Date();

var month = d.getMonth()+1;
var day = d.getDate();

var output = d.getFullYear() + '/' +
    (month<10 ? '0' : '') + month + '/' +
    (day<10 ? '0' : '') + day;

See this jsfiddle for a proof.

The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.
