Adding a '-' for a zipcode

When a user is inputting a zipcode into a textbox I want the '-' automatically inputted when they type in their 6th number.  How do I do this?

See if this jsfiddle helps

The main bit of code is:
$("#zip").keyup(function(event) {
    var value = $(this).val();
    var pattern = /^(\d{6}-\d{0,2}|\d{0,6})$/;
    if (!pattern.test(value)) {
        $(this).val($(this).val().replace(/\D/g, "").replace(/(\d{6})/, "$1-").replace(/(\d{6}-\d{1,2}).*/, "$1"))
    }
});

These are both good options but I don't know how to call them.

leakim971: Where do I put your code?  I read the link you attached but I don't really understand jquery.


Proculopsis: I understand yours better because the link shows me how to call the function, but where do I add the function?  When I tried to add it between:


<script language="JavaScript" type="text/javascript" src="scripts/jquery.js"></script>
<script>

   'Added the code here

</script>

I got an error when saving.  It said 'Some Unicode character in this file could not be saved in the current codepage...'

I must be adding the code in the wrong spot.

Any suggestions?

You need to put the following lineS in the head section of your page :
<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.maskedinput.js" type="text/javascript"></script>

Open in new window

DON'T FORGET TO UPDATE THE PATH OF BOTH FILES YOU DOWNLOAD AND PUT IN YOUR WEB SITE FOLDER :
jquery.maskedinput.js
jquery.js

Now, use the following :
<script type="text/javascript">
$(document).ready(function() {
    $("#zip").mask("999999-99"); // HERE << zip >> is the value of the ID attribute of your zip field
})
</script>

I gave leakim971 100 points because he showed me how to use jquery.  He didn't get all the points because I couldn't get the code to run in my program.

 Proculopsis got 400 points but I did need to change the numbers.  I needed 5 digits then '-' and then 4 digits.

Thanks guys for such good help.
