Answer 1

You can perform HTML form validation automatically without using javascript. The validation enabled by applying the required attribute to prevent form submission when the input is empty.

  <input type="text" name="uname" required />
  <input type="submit" value="Submit" />
</form>

Note: Automatic form validation does not work in Internet Explorer 9 or earlier.
