What's the best way to automatically insert slashes '/' in date fields

Question

I\'m trying to add functionality to input date fields so as when the users enters in digits, slashes \"/\" get automatically added.

So suppose I have the following

Answer 1

Update/Edit: Obviously the most simple solution today with widespread HTML5 support is to use .

For those complaining that it doesn't accommodate backspaces or pasting, I modified the original:

//Put our input DOM element into a jQuery Object
var $jqDate = jQuery('input[name="jqueryDate"]');

//Bind keyup/keydown to the input
$jqDate.bind('keyup','keydown', function(e){

  //To accomdate for backspacing, we detect which key was pressed - if backspace, do nothing:
    if(e.which !== 8) { 
        var numChars = $jqDate.val().length;
        if(numChars === 2 || numChars === 5){
            var thisVal = $jqDate.val();
            thisVal += '/';
            $jqDate.val(thisVal);
        }
  }
});

`
