Here all of the above outputs are giving a 10 digit number  but along with that the input field is accepting characters also  which is not the full solution  In order to set the 10 digit numbers only  we can use an input tag along with that type as number  and in that we can remove the up-down array by writing some small code in css which is shown below along with the input tag     lt input name  phone  maxlength  10  pattern   1-9  1  0-9  9   class  form-control  id  mobile   placeholder  Enter your phone Number  type  number  gt    input type number   -webkit-inner-spin-button  input type number   -webkit-outer-spin-button        -webkit-appearance  none      -moz-appearance  none      appearance  none      margin  0

try this    lt input type  text  name  country code  title  Error Message  pattern   1-9  1  0-9  9   gt     This will ensure   It is numeric  It will be max of 10 chars First digit is not zero

whereas you could use maxLength on the input  and some javascript validation  it will still be necessary to do server side validation anyway

whoever is checking this post in 2020  they can use  lt input inputmode  quot tel quot  gt  for phone numbers  10 digit    lt input inputmode  quot numeric quot  maxLength  5  gt  for numeric type and restrict to only 5 digits

You can use maxlength to limit the length  Normally for numeric input you d use type  number   however this adds a spinny box thing to scroll through numbers  which is completely useless for phone numbers  You can  however  use the pattern attribute to limit input to numbers  and require 10 numbers too  if you want     lt input type  text  maxlength  10  pattern   d 10   title  Please enter exactly 10 digits    gt

Please find below code if you want user to restrict with entering 10 digit in input control   lt input class  form-control  input-md text-box single-line  id  ContactNumber  max  9999999999  min  1000000000  name  ContactNumber  required  required  type  number   value  9876658688  gt    Benefits -    It will not allow to type any alphabets in input box because type of input box is  number  it will allow max 10 digits because max property is set to maximum possible value in 10 digits it will not allow user to enter anything less than 10 digits as we want to restrict user in 10 digit phone number  min property in code is having minimum possible value in 10 digits so it will tell user to enter valid 10 digit value not less than that
