To Check if email is in valid form we can use this script.

  1. <html>
  2. <head>
  3. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  4. <title>Email Validation Form</title>
  5. <script>
  6. function emailValidate(strEmail)
  7. {
  8. validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
  9.  
  10. if (strEmail.search(validRegExp) == -1)
  11. {
  12. alert("Invalid e-mail address");
  13. return false;
  14. }
  15. }
  16. </script>
  17. </head>
  18.  
  19. <body>
  20. <form id="form1" name="form1" method="post" action="">
  21.   <label>
  22.   <input type="text" name="email" id="email" />
  23.   </label>
  24.   <p>
  25.     <label>
  26.     <input type="submit" name="button" id="button" value="Submit"
  27.  onclick="return emailValidate(document.form1.email.value)" />
  28.     </label>
  29.   </p>
  30. </form>
  31. </body>
  32. </html>
