add dash in inputbox

Question

How can I make a input field that automatically adds a dash after six digits. Is should also only be possible to write numbers in the input field.

Can this be done using jQuery?

Borrowing code from this post: How to allow only numeric (0-9) in HTML inputbox using jQuery?

You can add a condition to capture length.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.0/jquery-ui.min.js"></script>

<script>
$(document).ready(function() {
    $("#txtboxToFilter").keydown(function(event) {
        // Allow: backspace, delete, tab, escape, and enter
        if ( event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 || 
             // Allow: Ctrl+A
            (event.keyCode == 65 && event.ctrlKey === true) || 
             // Allow: home, end, left, right
            (event.keyCode >= 35 && event.keyCode <= 39)) {
                 return;
        }
        else {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105 )) {   
                event.preventDefault(); 
            }   
        }

        if(  $("#txtboxToFilter").val().length == 6 )
       {
            event.target.value = event.target.value + "-";
       }
    });
});
</script>

<form>

<input type="text" id="txtboxToFilter">

</form>

You may want to modify the keyup handler to add a dash every 6 digits. This only adds the dash after the FIRST six digits, but you get the picture. — Blaise Swanwick, Oct 31 '12 at 18:12
It works. But it don't add the dash if you keep pressing just one digit on your keyboard. — Stefan, Oct 31 '12 at 18:14
You are right stefan. I always forget that users could just hold down a key...Anyways, i'll update the post — Blaise Swanwick, Oct 31 '12 at 18:16
This breaks pasting: ctrl+v does not work, and other forms of pasting override `keyup`, so get nor filtered, nor formatted. — WhyNotHugo, Jun 06 '15 at 03:10

jQuery('#inputFieldId').keydown(function(event) {
            var enteredValue = jQuery(this).val();
            if ( event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 || 
                   (event.keyCode == 65 && event.ctrlKey === true) || (event.keyCode >= 35 && event.keyCode <= 39) || 
                   (event.keyCode>=48 && event.keyCode<=57) || (event.keyCode>=96 && event.keyCode<=105)) // allow numbers
                {
                   if(enteredValue.length==6 && ((event.keyCode>=48 && event.keyCode<=57) || (event.keyCode>=96 && event.keyCode<=105)))
                   {
                    jQuery(this).val(enteredValue+"-")
                   }
               }
            else
            {
                event.preventDefault();
            }
        });

now corrected the code, try this.

Yes it works fine. But it dont add the dash if you just hold down one key. – Stefan Oct 31 '12 at 18:28
now i corrected the code and checking other conditions as per Blaise answer. I have tested the code and it allows number only with hold down key. – Bhushan Kawadkar Oct 31 '12 at 19:55
Thanks Bhushan. Work fine now =) – Stefan Oct 31 '12 at 20:54
Could it also be possible to type from the numpad? – Stefan Nov 01 '12 at 15:58
It isn't. Think I need to add this or something like that: event.keyCode>=48 && event.keyCode<=57 – Stefan Nov 01 '12 at 16:13
can you do one thing, add alert in the script and read event.keycode when entering from numpad and modify the script accordingly. – Bhushan Kawadkar Nov 01 '12 at 20:45
Added: || (event.keyCode>=96 && event.keyCode<=105) // to the first and second if condition. – Stefan Nov 01 '12 at 21:04
