Try this:

HTML

<div id=output></div>

JS

(function () {

    // Get current date

    var date = new Date();



    // Format day/month/year to two digits

    var formattedDate = ('0' + date.getDate()).slice(-2);

    var formattedMonth = ('0' + (date.getMonth() + 1)).slice(-2);

    var formattedYear = date.getFullYear().toString().substr(2,2);



    // Combine and format date string

    var dateString = formattedMonth + '/' + formattedDate + '/' + formattedYear;



    // Reference output DIV

    var output = document.querySelector('#output');



    // Output dateString

    output.innerHTML = dateString;

})();
