Hi Sirisha,

You will need to write an onchange client script on your field or variable which would be something like this:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
    if (!newValue.match(mailformat)) {
        alert('You have entered an invalid email address!');
    }

}

Please mark my answer helpful/correct if this works for you.

Regards,

Vismit

Hi @sirisha navuduri ,

Try this code I have tested code in my PDI.

Change the field name as per your requirement.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    var Reformat = /^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$/;
    if (!Reformat.test(newValue)) {
		g_form.clearValue("description");
        g_form.showFieldMsg("description",'Please enter valid email address!',"error");
    }
	
	

}

Mark as Correct answer and Helpful if applicable.

If this is for Service Catalog, you can use OOB email validation.

See https://docs.servicenow.com/bundle/sandiego-servicenow-platform/page/product/service-catalog-managem...

OOB Email validation rule can be seen below:
