var code = document.getElementById("password");

var strengthbar = document.getElementById("meter");
var display = document.getElementsByClassName("textbox")[0];

code.addEventListener("keyup", function() {
  checkpassword(code.value);
});


function checkpassword(password) {
  var strength = 0;
  if (password.match(/[a-z]+/)) {
    strength += 1;
  }
  if (password.match(/[A-Z]+/)) {
    strength += 1;
  }
  if (password.match(/[0-9]+/)) {
    strength += 1;
  }
  if (password.match(/[$@#&!]+/)) {
    strength += 1;

  }

  if (password.length < 6) {
    display.innerHTML = "minimum number of characters is 6";
  }

  if (password.length > 12) {
    display.innerHTML = "maximum number of characters is 12";
  }

  switch (strength) {
    case 0:
      strengthbar.value = 0;
      break;

    case 1:
      strengthbar.value = 25;
      break;

    case 2:

// Commonly used regular expression

// Check 2-9 characters, false if not matched, true if matched
const validateName = (name) => {
   const reg = /^[\u4e00-\u9fa5]{2,9}$/;
   return reg.test(name);
};
// Verify phone number
const validatePhoneNum = (mobile) => {
   const reg = /^1[3,4,5,6,7,8,9]\d{9}$/;
   return reg.test(mobile);
};
// Check passwords consisting of 0 to 8
//uppercase and lowercase 
//alphanumeric underscores
const validatePassword = (password) => {
   const reg = /^[a-zA-Z0-9_]{0,9}$/;
   return reg.test(password);
};
