HTML5 Features - Email Inputs

7. Email Inputs

If we apply a type of “email” to form inputs, we can instruct the browser to only allow strings that conform to a valid email address structure. That’s right; built-in form validation will soon be here! We can’t 100% rely on this just yet, for obvious reasons. In older browsers that do not understand this “email” type, they’ll simply fall back to a regular textbox.
  1. <!DOCTYPE html>  
  2.   
  3. <html lang="en">  
  4. <head>  
  5.     <meta charset="utf-8">  
  6.     <title>untitled</title>  
  7. </head>  
  8. <body>  
  9.     <form action="" method="get">  
  10.         <label for="email">Email:</label>  
  11.         <input id="email" name="email" type="email" />  
  12.   
  13.         <button type="submit"> Submit Form </button>  
  14.     </form>  
  15. </body>  
  16. </html>  
Email Validation
At this time, we cannot depend on browser validation. A server/client side solution must still be implemented.
It should also be noted that all the current browsers are a bit wonky when it comes to what elements and attributes they do and don’t support. For example, Opera seems to support email validation, just as long as the name attribute is specified. However, it does not support the placeholder attribute, which we’ll learn about in the next tip. Bottom line, don’t depend on this form of validation just yet…but you can still use it!
