Im trying to confirm if the password strength is strong or weak and is the password is strong and when I submit it should have alert message like "You Have Strong Password" and when its weak "Invalid Password"
This is what I am now.
function checkPasswordStrength() {
var passwordStrength = false;
var number = /([0-9])/;
var alphabets = /([a-zA-Z])/;
var special_characters = /([~,!,@,#,$,%,^,&,*,-,_,+,=,?,>,<])/;
if ($('#password').val().length < 8) {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('weak-password');
$('#password-strength-status').html("Weak (should be atleast 8 characters.)");
} else {
if ($('#password').val().match(number) && $('#password').val().match(alphabets) && $('#password').val().match(special_characters)) {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('strong-password');
$('#password-strength-status').html("Strong");
return passwordStrength = true;
} else {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('medium-password');
$('#password-strength-status').html("Medium (should include alphabets, numbers and special characters.)");
}
}
}
$('#btn-submit').click(function () {
if (passwordStrength == false) {
alert("INVALID PASSWORD");
} else {
alert("You have Strong PASSWORD");
}
</script>
its for Educational Purpose only im just starting jquery.. thank you in advance..
It looks like the variable scope is incorrect. var passwordStrength should be put outside of the checkPasswordStrength function.
var passwordStrength
function checkPasswordStrength() {
....
You need to call the function instead of just checking your variable. So rather do
$('#btn-submit').click(function () {
if (checkPasswordStrength() === false) {
instead of
$('#btn-submit').click(function () {
if (passwordStrength == false) {
Then, instead of return passwordStrength = true; you should do just passwordStrength = true and add a return passwordStrength to the very end of your function so it will return either false or true.
