Validating email address with javascript

Here’s the code: function validate My Form() { // Create validation tracking variables var valid = true; var validation Message = 'Please correct the following errors:\r\n'; // Validate first name if (Element By Id('Text First Name').value.length == 0) { validation Message = validation Message + ' - First name is missing\r\n'; valid = false; } // Validate last name if (Element By Id('Text Last Name').value.length == 0) { validation Message = validation Message + ' - Last name is missing\r\n'; valid = false; } // Validate telephone if (Element By Id('Text Telephone').value.length == 0) { validation Message = validation Message + ' - Telephone is missing\r\n'; valid = false; } // Validate email if (Element By Id('Text Email').value.length == 0) { validation Message = validation Message + ' - Email is missing\r\n'; valid = false; } // Validate years on internet if (Element By Id('Text Internet Years').value.length == 0) { validation Message = validation Message + ' - Years using internet is missing\r\n'; valid = false; } // Display alert box with errors if any errors found if (valid == false) { alert(validation Message); } return valid; } Our first order of business in our validation function is to create two variables.There are two basic types of validation: server-side and client-side.

For the purposes of this example we are keeping it simple and making everything required.

However, before we can begin validating we need to create a Java Script function that handles all of our validation.

Is there a way to show the errors in modal-popup only.

Whether you are accepting input for something as simple as a guestbook or something as complex as an employment application, it makes sense to check the user’s input before committing it to a database or even an email.

While client-side validation is not as secure as server-side validation, it does not require a roundtrip to the server.

This means that validation occurs quickly and does not cause the page to reload or send anything to the server.
