Tirohia te Kaha Kupuhipa me te JavaScript, jQuery ranei me nga Whakaaturanga Tonu (Me nga Tauira-Taha-Tumau, Me!)

I mahia e au etahi rangahau mo te rapu tauira pai mo te kaitaki Kaha Kaha e whakamahi ana JavaScript a Ngā Whakaaro Whaiaro (regex). I roto i te tono i aku mahi, ka tukuna e matou he panui ki te manatoko i te kaha o te kupuhipa, a he tino uaua ki a maatau kaiwhakamahi.

He aha te Regex?

Ko te whakahua i ia wa ko te raupapatanga o nga taera e tautuhi ana i te tauira rapu. I te nuinga o te waa, ko nga tauira e whakamahia ana e nga raparapa rapu algorithm kitea or kitea ka whakahou mahi i runga i nga aho, hei whakamana ranei whakauru. 

Ko tenei tuhinga kaore ke e ako i a koe ki nga whakaputa i nga waa katoa. Me mohio noa ko te kaha ki te whakamahi i nga Whakahuahanga Auau ka tino maamaa i to whanaketanga i a koe e rapu tauira ana i te tuhinga. He mea nui ano kia mahara ko te nuinga o nga reo whanake kua arotau ki te whakamahi i nga korero auau… no reira kaua te kowhiri me te rapu taahiraa i tetahi-taahiraa, he tere rawa atu a Regex i te kaituku me te taha-kaihoko.

I tino rapuhia e au te paetukutuku i mua i taku kitenga he tauira o etahi Whakaaturanga Tonu nui e rapu ana i te huinga o te roa, nga tohu, me nga tohu. Heoi, he iti rawa te waehere mo taku reka, he mea whakarite mo .NET. Na ka whakangwarihia e ahau te waehere ka hoatu ki te JavaScript. Ma tenei ka whakamanahia te kaha o te kupuhipa i roto i te waa-a-waa i runga i te kaitirotiro a te kiritaki i mua i te tuku whakamuri… me te tuku urupare ki te kaiwhakamahi mo te kaha o te kupuhipa.

Patohia He Kupuhipa

Mo ia whiu o te papapātuhi, ka whakamatautauhia te kupuhipa ki te whakaputa i nga waa noa ka tukuna he urupare ki te kaiwhakamahi i roto i te whanganga o raro.

Mahinga Kaha Kupuhipa JavaScript

te Ngā Whakaaro Whaiaro mahi tino pai ki te whakaiti i te roa o te waehere. Ko tenei mahi Javascript he tirotiro i te kaha o te kupuhipa me te whakakore he ngawari, he reo, he uaua, he tino uaua ranei ki te matapae. I te wa e momo ana te tangata, ka whakaatu nga tohutohu mo te akiaki kia kaha ake. Ka whakamanahia te kupuhipa i runga i:

• roa – Mēnā kei raro te roa, neke atu rānei i te 8 pūāhua.
• Take Ranu – Mēnā he pūāhua o runga me te pūāhua iti o te kupuhipa.
• Numbers – Mena kei roto i te kupuhipa nga nama.
• Hoahoa Motuhake – Mēnā kei roto i te kupuhipa ngā pūāhua motuhake.

Ka whakaatu te mahi i te uaua me etahi tohutohu mo te whakapakeke ano i te kupuhipa.

function checkPasswordStrength(password) {
  // Initialize variables
  var strength = 0;
  var tips = "";

  // Check password length
  if (password.length < 8) {
    tips += "Make the password longer. ";
  } else {
    strength += 1;
  }

  // Check for mixed case
  if (password.match(/[a-z]/) && password.match(/[A-Z]/)) {
    strength += 1;
  } else {
    tips += "Use both lowercase and uppercase letters. ";
  }

  // Check for numbers
  if (password.match(/\d/)) {
    strength += 1;
  } else {
    tips += "Include at least one number. ";
  }

  // Check for special characters
  if (password.match(/[^a-zA-Z\d]/)) {
    strength += 1;
  } else {
    tips += "Include at least one special character. ";
  }

  // Return results
  if (strength < 2) {
    return "Easy to guess. " + tips;
  } else if (strength === 2) {
    return "Medium difficulty. " + tips;
  } else if (strength === 3) {
    return "Difficult. " + tips;
  } else {
    return "Extremely difficult. " + tips;
  }
}

Mena kei te pirangi koe ki te whakahou i te tae o te pito, ka taea ano e koe ma te whakahou i te waehere i muri i te // Return results raina.

// Get the paragraph element
  var strengthElement = document.getElementById("passwordStrength");

  // Return results
  if (strength < 2) {
    strengthElement.textContent = "Easy to guess. " + tips;
    strengthElement.style.color = "red";
  } else if (strength === 2) {
    strengthElement.textContent = "Medium difficulty. " + tips;
    strengthElement.style.color = "orange";
  } else if (strength === 3) {
    strengthElement.textContent = "Difficult. " + tips;
    strengthElement.style.color = "black";
  } else {
    strengthElement.textContent = "Extremely difficult. " + tips;
    strengthElement.style.color = "green";
  }

jQuery Kupuhipa Kaha Mahi

Ki te jQuery, karekau e tika kia tuhia te puka me te whakahou whakaurunga:

<form>
    <label for="password">Enter password:</label>
    <input type="password" id="password">
    <p id="password-strength"></p>
</form>

Ka taea hoki te whakarereke i te tae o nga karere mena ka pirangi matou. 

$(document).ready(function() {
    $('#password').on('input', function() {
        var password = $(this).val();
        var strength = 0;
        var tips = "";
  
        // Check password length
        if (password.length < 8) {
            tips += "Make the password longer. ";
        } else {
            strength += 1;
        }
  
        // Check for mixed case
        if (password.match(/[a-z]/) && password.match(/[A-Z]/)) {
            strength += 1;
        } else {
            tips += "Use both lowercase and uppercase letters. ";
        }
  
        // Check for numbers
        if (password.match(/\d/)) {
            strength += 1;
        } else {

            strength += 1;
        } else {
            tips += "Include at least one special character. ";
        }
  
        // Update the text and color based on the password strength
        var passwordStrengthElement = $('#password-strength');
        if (strength < 2) {
            passwordStrengthElement.text("Easy to guess. " + tips);
            passwordStrengthElement.css('color', 'red');
        } else if (strength === 2) {
            passwordStrengthElement.text("Medium difficulty. " + tips);
            passwordStrengthElement.css('color', 'orange');
        } else if (strength === 3) {

            passwordStrengthElement.css('color', 'green');
        }
    });
});
