Hi,

You need to build a JS like this bellow one where you will add all the keycode of the char not allowed.

var InputField = document.getElementById($parameters.WidgetId);InputField.addEventListener("keydown", function(event) {    keypressed = event.keyCode || event.which || event.charCode;    if (keypressed == 69 || keypressed == 107 || keypressed == 187) {       event.preventDefault();     }})

Or you can use this component: https://www.outsystems.com/forge/component-overview/8005/restrict-chars-reactive

Hello

You can use Forge components available for the use case, you just need to write Regex pattern basis on what characters are required.

here are some which you can use

• https://www.outsystems.com/forge/component-overview/8005/restrict-chars-reactive
• https://www.outsystems.com/forge/component-overview/15037/disable-characters-through-regex-reactive
• https://www.outsystems.com/forge/component-overview/7838/input-mask-react
• https://www.outsystems.com/forge/component-overview/7819/input-mask-reactive

I hope this helps

Hii @Vishal Veerakumar,

firstly you need to check you email format/email is valid or not which is already done but when you start apply regex to find special character to prevent user enter special character other that email format 

which is 
somestring@somestring.somestring

above is valid email format, so @ sign can not come more than one time but . (dot) can come like

somestring.somestring2@gmail.com

above should be a valid email address this can be achieve by JS regExp which i have modified little bit.

-----------JS code-----------

email = document.getElementById($parameters.widgetId).value;

// Email is valid, check for unwanted special characters

var emailreg = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;

if (emailreg.test(email)) {

    var specialCharRegex = /[!#$%^&*()_+{}\[\]:;<>,?~\\/-]/;

    if (specialCharRegex.test(email)) {

        // There are unwanted special characters

        alert('Email contains special characters other than the required format.');

        $parameters.IsValidEmail = false;

    } else {

        // Email is valid and doesn't contain unwanted special characters

        $parameters.IsValidEmail = true;

        $parameters.IsValidEmail = true;

    }

} else {

    $parameters.IsValidEmail = false;

}

I am also attaching OML file
