Html 5 Mobile number validation

In this post, we will be learning mobile number validation by HTML5. It is done by adding few attributes to the input field.

Code

<form action="">
  <input type="text" maxlength="10"  pattern="[0-9]{10}" title="Enter your mobile number"
     required>
  <input type="submit">
</form>

 The above code validates a 10 digit number. As seen in the code, it is very simple no JavaScript or jQuery code is required. The code is explained below.
  •  Input text field for entering the number.
  • Max length to restrict the characters entered in only 10.
  • Pattern attribute specifies the expression for checking the value of an input field. The pattern is based on the regular JavaScript expression. The square brackets '[ ]' tells whether to validate text a-z or numbers 0-9 and flower bracket '{ }' for telling the number of characters to enter.
  • Required attribute is added if the phone number is mandatory.
  • The title attribute is for describing the pattern of the users.


 More Examples for better understandings:

<form action="">
  <input type="password" maxlength="4"  pattern="[0-9]{4}"  required>
  <input type="submit">
</form>

<form action="">
  <input type="search"  pattern="[a-z]{10}" title="Enter ten character search keyword">
  <input type="submit">
</form>
