How to validate Email field through Client script

Hi Jyoti,

By using below client script you can validate email id on custom form.

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

 //If the page isn't loading

 if (!isLoading) {

 //If the new value isn't blank

 if(newValue != '') {

  var oldV = oldValue;

  var validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;

var strEmail = g_form.getValue('u_company_official_email_id');   //here u_company_official_email_is is my field actual name 

 if (strEmail.search(validRegExp) == -1)

 {

 alert('A valid e-mail address is required eg:-abc@domain.com.');

 g_form.setValue('u_company_official_email_id','oldV');

 }

 }

 }

}

Mark my answer as correct/helpful if it works for you.

The above works but this is much cleaner and more efficient:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
    if (newValue.search(validRegExp) == -1) {
        alert('A valid e-mail address is required eg:-abc@domain.com.');
        g_form.setValue('email', '');
    }
}

Hello @GregLusk 

Can you help me in altering the regular expression which validates whether the entered email contains @gmail or not.

For example abc@outlook.com it should not take. Forward email should only take input as abc@gmail.com. Please  help me.

Thanks in advance
