jQuery password strength checker

Question

I\'m quite new to jQuery, and I\'ve written a simple function to check the strength of a password for each keypress.

The idea is that every time a user enters a char

Answer 1

best way is this

function password_validate(txt) {
  var val1 = 0;
  var val2 = 0;
  var val3 = 0;
  var val4 = 0;
  var val5 = 0;
  var counter, color, result;
  var flag = false;
  if (txt.value.length <= 0) {
    counter = 0;
    color = "transparent";
    result = "";
  }
  if (txt.value.length < 8 & txt.value.length > 0) {
    counter = 20;
    color = "red";
    result = "Short";
  } else {
    document.getElementById(txt.id + "error").innerHTML = " ";
    txt.style.borderColor = "grey";
    var regex = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[^a-zA-Z0-9])(?!.*\s).{8,15}$/;
    //  document.getElementById("pass_veri").style.display="block";
    var fletter = /[a-z]/;
    if (fletter.test(txt.value)) {
      val1 = 20;

    } else {
      val1 = 0;
    }
    //macth special character
    var special_char = /[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/;
    if (special_char.test(txt.value)) {
      val2 = 30;
    } else {
      val = 0;
    }
    /*capital_letter*/
    var cap_lett = /[A-Z]/;
    if (cap_lett.test(txt.value)) {
      val3 = 20;
    } else {
      val = 0;
    }
    /*one numeric*/
    var num = /[0-9]/;
    if (num.test(txt.value)) {
      val4 = 20;
    } else {
      val4 = 0;
    }
    /* 8-15 character*/
    var range = /^.{8,50}$/;
    if (range.test(txt.value)) {
      val5 = 10;
    } else {
      val5 = 0;
    }
    counter = val1 + val2 + val3 + val4 + val5;

    if (counter >= 30) {
      color = "skyblue";
      result = "Fair";
    }
    if (counter >= 50) {
      color = "gold";
      result = "Good";
    }
    if (counter >= 80) {
      color = "green";
      result = "Strong";
    }
    if (counter >= 90) {
      color = "green";
      result = "Very Strong";
    }
  }
  document.getElementById("prog").style.width = counter + "%";
  document.getElementById("prog").style.backgroundColor = color;
  document.getElementById("result").innerHTML = result;
  document.getElementById("result").style.color = color;
}
