validation regex

[Buddy 1]

Hi,

I have a field validation which can allow alphanumeric and special characters with 10 digit . But if the value entered is only alphabet or only special characters , it should not allow.

for eg:

the validation can be like --> 123$nj-jka

the validation should not be like --> asdfghnjkr 

the validation should not be like --> @#$%^&*()_

Can anyone help?

Thanks in advance!

Hi @Buddy 1 ,

use the below code

function validateField(value) {
  // Check if value is 10 characters long
  if (value.length !== 10) {
    return false;
  }

  // Check if value is alphanumeric or contains special characters
  var regex = /^(?=.*[a-zA-Z])(?=.*[@$!%*#?&])[a-zA-Z\d@$!%*#?&]+$/;
  if (!regex.test(value)) {
    return false;
  }

  // Check if value is only alphabetical or only special characters
  var letters = /^[A-Za-z]+$/;
  var specialCharacters = /^[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/;
  if (letters.test(value) || specialCharacters.test(value)) {
    return false;
  }

  return true;
}

Hi @Teja11 ,

Thanks for the code, Is it possible to make the same using validation regex . 

Can you help me with the regular expression .

Thanks in advance!

sure here's the one line regular expression

/^(?=.*[a-zA-Z])(?=.*[@$!%*#?&])[a-zA-Z\d@$!%*#?&]{10}(?<![a-zA-Z])(?<![@$!%*#?&])$/

[Teja11]

Example:

var regex = /^(?=.*[a-zA-Z])(?=.*[@$!%*#?&])[a-zA-Z\d@$!%*#?&]{10}(?<![a-zA-Z])(?<![@$!%*#?&])$/;
var inputValue = "123$nj-jka";

if (regex.test(inputValue)) {
  // Input value is valid
} else {
  // Input value is invalid
}
