Function in JS returns undefined
- by megapool020
Hello there,
I have the following problem. The alert allways returns undefined, but I know it has a value. What am I doing wrong. I'm out of solutions...
I'm using JQUERY jquery-1.4.2.min.js
Tnx in advance
$(document).ready(function(){
$('#generateButton').click(createIBAN);
});
function createIBAN(){
//---- First check if a bank has been selected,
//---- if not, then show error
if($('#selectBank').val()==''){
alert('Selecte a bank!');
}else{
var bankAccount = generateBankAccount();
alert(bankAccount);
}
return false;
}
function generateBankAccount(){
//---- Create "elfproef" bankaccount
var bankAccount = '';
//---- Set the amount of digits in a bankaccount
digitAmount = 9;
//---- Make random digitstring
for (var i = 0; i < digitAmount; i++) {
bankAccount += Math.floor(Math.random() * digitAmount);
}
//---- validate the string, if not "elf-proef"
if (elfProef(bankAccount)==false) {
//---- regenerate the string
generateBankAccount();
}else{
return bankAccount;
}
}
function elfProef(bankAccount) {
//---- set sum to 0 and start the for-loop for counting
var sum = 0;
for (var i = 0; i < digitAmount; i++) {
//---- for every digit multiply it times 9 - number
//---- of the digit and count it to the sum var
sum += bankAccount.charAt(i) * (digitAmount - i);
}
//---- Check if sum can be devided by 11 without having ##,##
if(sum % 11==0){
//---- return true means string is "elf-proef"
return true;
}else {
//---- String is not "elf-proef", try again
return false;
}
}
