using condition in jquery onclick button - html

Question

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..

Answer 1

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.

Answer 2

It looks like the variable scope is incorrect. var passwordStrength should be put outside of the checkPasswordStrength function.
var passwordStrength
function checkPasswordStrength() {
....
