I had recently posted on Add a Custom Validation Method to the jQuery Validation Plugin. A user asked me over twitter asking how to validate IP address using this method.
Here’s the same custom validation method that now validates an IP address. I am using regex to do so (The regular expression was searched on the net)
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Validate IP Address using jQuery</title>
<script type="text/javascript"
src="http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.min.js">
</script>
<script type="text/javascript" src=
"http://ajax.microsoft.com/ajax/jquery.validate/1.7/jquery.validate.min.js">
</script>
<script type="text/javascript">
$(function() {
$.validator.addMethod('IP4Checker', function(value) {
var ip = "^(?:(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.){3}" +
"(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)$";
return value.match(ip);
}, 'Invalid IP address');
$('#form1').validate({
rules: {
ip: {
required: true,
IP4Checker: true
}
}
});
});
</script>
</head>
<body>
<form id="form1">
<input id="ip" name="ip" type="text" />
<input id="Submit1" type="submit" value="submit" />
</form>
</body>
</html>
On running the code, enter an IP address. The validation detects an invalid IP and displays the message “Invalid IP address”
Once you enter a valid IP, you can submit the form

Wrong regexp!
True is:
$.validator.addMethod('IP4Checker', function(value) {
var ip = /^(25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[0-9]{2}|[0-9])(\.(25[0-5]|2[0-4][0-9]|[0-1][0-9]{2}|[0-9]{2}|[0-9])){3}$/;
return value.match(ip);
});
Hi,
I tried your example and i think a found a little mistake.
You should user "\\." to escape the dot, because the '\' itselfs needs to be escaped. If you don't it means any character can be a seperator for the ip quartet.
posee errores varios....... grcias de igual forma ya pude adaptarlo
