HTML5 phone number validation with pattern

Question

I m using HTML5 form validation to validate phone numbers from India   Phone numbers from India are 10 digits long  and start with 7  8  or 9   For example    7878787878 9898989898 8678678878   These phone numbers are valid  but    1212121212 3434545464 6545432322   are invalid   Suggest a pattern that can detect valid India phone numbers   So far  my pattern is  0-9  10   but it doesn t check if the first digit is 7  8  or 9

This code will accept all country code with + sign

<input type="text" pattern="[0-9]{5}[-][0-9]{7}[-][0-9]{1}"/>

Some countries allow a single "0" character instead of "+" and others a double "0" character instead of the "+". Neither are standard.

The regex validation for india should make sure that  91 is used  then make sure that 7  8 9  is used after  91 and finally followed by 9 digits      91 7 d 8 d 9 d  d 9     Your original regex doesn t require a     at the front though   Get the more information from below link  w3schools com jsref jsref obj regexp asp
