Email validation

[Abhilasha_123]

Hi Team,

As there is a need for our requirement, could you please help with creating new script with below conditions.

Email validation - Email that is ending with .AB should throw an error saying, 'Email ending with .AB are not accepted.'
Email must contain the value @, If it does not contain @ then throw an error saying "Email must contain @"
Spaces while entering email ID is not allowed, if it contains spaces then throw an error saying, "spaces are not allowed."

Also, if a check box is flagged, then make the email field ready only.

Thank you!!

You can write an onChange client script and mention below code

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

if (g_form.getValue("Check_BOX_backend_name")) {

 g_form.setReadOnly('u_email', 'true');

 }

return;

 }


if (g_form.getValue("Check_BOX_backend_name")) {

 g_form.setReadOnly('u_email', 'true');

 }else{

 g_form.setReadOnly('u_email', 'false');

 }

if (newValue.endsWith('.AB')) {

 alert('Email cannot end with .AB');

 }

if (newValue.indexOf('@') == -1) {

 alert('Email must contain @ symbol.');

 }

if (/\s/.test(newValue)) {

 alert('Spaces are not allowed in the email.');

 }

}

Question 1 : 

How to add condition for validating email that email should not have space at the start and at the end and if we have space it should throw an error using client script.

Hi @Abhilasha_123 

You can use a client script in ServiceNow to enforce these conditions on the email field. Below is an example script that you can use in the "onChange" client script of your email field.

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

    var emailValue = g_form.getValue('your_email_field'); 
    var checkBoxChecked = g_form.getValue('checkbox_field'); 

    // Condition 1: Email ending with .AB
    if (emailValue.toLowerCase().endsWith('.ab')) {
        alert('Email ending with .AB is not accepted.');
        g_form.setValue('your_email_field', oldValue); 
        return;
    }

    // Condition 2: Email must contain @
    if (!emailValue.includes('@')) {
        alert('Email must contain @');
        g_form.setValue('your_email_field', oldValue); 
        return;
    }

    // Condition 3: Spaces are not allowed
    if (emailValue.includes(' ')) {
        alert('Spaces are not allowed in the email.');
        g_form.setValue('your_email_field', oldValue); 
        return;
    }

    // Condition 4: Make the email field read-only if the checkbox is checked
    g_form.setReadOnly('your_email_field', checkBoxChecked);
}
