Validation of standard fields on Comment, Request or Registration Form

Recommended Posts

I am trying to make a simple "Submit a Request" form,

which will  have fields like first name, Last name, email address, phone number, request, etc.

Field names are like C_FirstName, C_Surname, C_Email, C_Phone, C_Request 

I want to validate text entries in the following fields as follows:

First / Last name: No numerical characters are allowed

Email Address : authenticate email according to https://www.w3resource.com/javascript/form/email-validation.php

mobile no.: formatting and checking as per 


So far I have the phone script working, but my adaptation of the email script (or the combination of the two in the footer of the form) doesn't check the entry in the Email Address field.

Any help sincerely appreciated



W3's  ValidateEmail Script below:

function ValidateEmail(mail)


if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(myForm.emailAddr.value))


return (true)


alert("You have entered an invalid email address!")

return (false)

In your submission or update page for Email field you can select EMAIL special element  from Form Element dropdown. To not let user enter numbers


To prevent user from entering numbers for First_name field on submission page you can have:


document.getElementById('InsertRecordFirst_Name').onkeyup= function(v_e){

v_e = v_e || window.event;
    if (v_e.keyCode > 47 && v_e.keyCode< 58) {

       this.value = this.value.substr(0, this.value.length - 1);
return false;
