Hi all. I need help with the javascript code for Social security number in the xxx-xx-xxxx format. Any help will be greatly appreciated.

What do you mean by "JavaScript code"? Are you looking for a regular expression to match that pattern? If so =

var ssnPattern = /^\d{3}-\d{2}-\d{4}$/;

That assumes that the SSN is the only value being tested. In other words, it's not buried in a longer string.

Dave I need it in a form field I am creating in a pdf, so that when someone fills that portion of the pdf, the numbers will appear in the format I stated above without them keying in the dash.

Try this:

<body>

<form id="form1" name="form1" method="post">

<label for="ssn">Social Security Number:</label>

<input type="text" name="ssn" id="ssn">

<input type="submit" name="submit" id="submit" value="Submit">

</form>

<script>

var ssn = document.getElementById('ssn');

ssn.addEventListener('keyup', function() {

if (!this.value.match(/^\d+$/)) {

alert('Please use numbers only');

}

}, false);

ssn.addEventListener('blur', function() {

if (!this.value.match(/^\d{9}$/)) {

alert('SSN should contain 9 digits');

} else {

var updated = this.value.replace(/^(\d{3})(\d{2})(\d{4})$/, '$1-$2-$3');

this.value = updated;

}

})

</script>

</body>
