Here, in this post I'll show you an example on how to enter only numbers or allow only numbers with a decimal in a textbox using Java Script. Ascci stands for “American Standard Code for Information Interchange”.
So, just to make sure that user entered the email address in the correct format, it’s necessary to include email validation code inside the validation codes.Simply the validation will remove all non-digits and permit only phone numbers with 10 digits. View the example in the browser Flowchart: Validate an international phone number with country code Now, let's see how to validate a phone number with country code, either in 24-0455-9034, 21.3789.4512 or 23 1256 4587 format.Sometimes situations arise (input a phone number, zip code or credit card number) when the user should fill a single or more than one fields with numbers (0-9) in an HTML form.I'm trying to get my login form to only validate if only numbers were inputted. I can it to work if the input is only digits, but when i type any characters after a number, it will still validate etc.
