[deepika46]

Hello experts,

Consider 2 fields,

a=xyz@yahoo.com

I have to validate these 2 email and URL values in seriver side script 

Can anyone please help me. I am new to ServiceNow scripting

Hi @deepika46 

We can achieve it by defining these fields under Email and URL type.

And also, we can create our own validation.

1. Define your own Regex (you can also refer to OOTB Regex for Email and URL)
2. Create your OnSubmit Client Script. Sample below

var regex = /^(?![\.])[a-zA-Z0-9!#$%*\/?|^{}`~&'\+\-=_.]+(?<![.]+)@(?![\.-])[a-zA-Z0-9-_\.]+(\.[a-zA-Z0-9_]+)$/;
if(!regex.test(newValue)){
	g_form.showErrorBox('<field_name>', 'Email is not valid');
	return false;
}

Reference OOTB Regular Expression:

Let me know if it works for you

Hi @deepika46 ,

Certainly! You can validate the email and URL values in ServiceNow using server-side scripting. Below are the steps and examples for validating an email address and a URL within a ServiceNow server-side script.

### Validating Email Address:

To validate an email address, you can use a regular expression pattern to match the email format. Here's an example of how you can validate the `a` field as an email address:

(function() {

    var emailPattern = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;

    var a = 'xyz@yahoo.com'; // Replace this with your actual field value



    if (emailPattern.test(a)) {

        gs.info('Valid email address: ' + a);

    } else {

        gs.info('Invalid email address: ' + a);

    }

})();

In this example, the `emailPattern` regular expression is used to validate the `a` field as an email address. If it matches the email format, it's considered valid.

### Validating URL:

To validate a URL, you can use a regular expression pattern to match the URL format. Here's an example of how you can validate the `b` field as a URL:

(function() {

    var urlPattern = /^(https?|ftp):\/\/[^\s/$.?#].[^\s]*$/;

    var b = 'https://DE-QA-001.servicenow/asdefdd'; // Replace this with your actual field value



    if (urlPattern.test(b)) {

        gs.info('Valid URL: ' + b);

    } else {

        gs.info('Invalid URL: ' + b);

    }

})();

In this example, the `urlPattern` regular expression is used to validate the `b` field as a URL. If it matches the URL format, it's considered valid.

Please note that these regular expressions are basic and may not cover all edge cases. Adjust the regular expressions according to your specific validation requirements. These scripts can be executed in a background script in ServiceNow to validate the provided email and URL values.
