IF / else语句和运算符

Question

I working on a form but I have some troubles with the last if statement ( it's not working.

count is global and start as 0 , for each field with the correct character filled in this will happen: count = count+1;

but if I clicked submit and leave 2 fields with not the correct character

( that should be count = 6 ) it doesn't give me an alert but skips it

this is how it should be.

1. check if password equals confirm_password
2. check if fields or not empty
3. check if fields have the correct characters ( count start as count = 0 , foreach field that is correct it it goes count = count +1, in totaal it can get 8 but at 6 it still keeps submitting).

 function validateForm() { var fields = ["voornaam", "achternaam", "Email", "Wachtwoord", "Herhaal_Wachtwoord", "Straatnaam", "Huisnummer", "Postcode", "Woonplaats", "Telefoonummer"]; if (pass1.value !== pass2.value) { alert("Wachtwoord komen niet overeen"); return false; } var l = fields.length; var fieldname; for (i = 0; i < l; i++) { fieldname = fields[i]; if (document.forms["register"][fieldname].value === "") { alert(fieldname + " can not be empty"); return false; } } if (count < 8) { alert("iets is niet goed ingevuld"); return false; } } 

Answer 1

You have returned the false boolean before you have given the alert prompt! Just change the last if statement like this:

if (count < 8) {
    alert("iets is niet goed ingevuld");
    return false;
}
