/get variables from form and check rules/
function validate(){
// initialize local variables
var errMsg = ""; // stores the error message
var result = true; // assumes no errors
function validate(){
// initialize local variables
var errMsg = ""; // stores the error message
var result = true; // assumes no errors
hm okey
because it does nothing
cuz cardmatch function wont populate the errMsg variable of the valdiate function
it make more sense to pass directly the cardmatch function
or execute cardmatch function from the valdiate function
validate*
var cardnumber = document.getElementById("cardnumber").value;
alert ("Card stored: " +cardnumber);
so it seems like values are not getting parsed
oh
i mean, it was missing
I mean where should I add the ) ?
and one advice, dont check "falsey" values - false, undefined, null are considered as "falsey" values in javascript
so if just check given variable or property from some object it is enough in most cases to do
if(sessionStorage.firstname){ instead of if(sessionStorage.firstname != undefined){
error message comes up empty
I mean the alert message
and its because it is executed before the form is submitted
because the async nature of javascript
replace that ".onsubmit = validate" with ".onsubmit = cardmatch" it make more sense
okey okey.. wait a min :)
is there totally requirement to have validate function, are you sure?
cool
but the thing is if the error message comes up, it doesnt stop being executed
it should stop from doing anything until user enter a valid number
