[Solved] how to use json array for password validation?

by


Don’t put the / around the expression. Then you can convert it to a regular expression with new RegExp, and test the password with it. You can loop with .every(), which will perform tests as long as they’re successful.

var pwdarray = {
  "pwd": [{
      "TEXT": "Password must be at least 6 character(s) long.",
      "EXPRESSION": "^(.){6,}$"
    },
    {
      "TEXT": "Password must contain at least 1 lowercase letter(s).",
      "EXPRESSION": "[a-z]"
    }
  ]
}
$("#check").click(function() {
  var pswd = $("#pass").val();
  $("#error").text("Password is good").addClass('valid').removeClass('invalid');
  pwdarray.pwd.every(({
    TEXT: text,
    EXPRESSION: exp
  }) => {
    if (!new RegExp(exp).test(pswd)) {
      $("#error").text(text).addClass('invalid').removeClass('valid');
      return false;
    } else {
      return true;
    }
  });
});
.invalid {
  color: red;
}

.valid {
  color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="pass">
<button id="check">Check</button>
<div id="error"></div>
