Hi Matt,
I'm trying to compare values to avoid a person to be present twice in
the list !
I've already tried the $F function with no success...
Trying your code (putting in an array) give me (with 3 iteration)
var arr = [];
// countUser == 3 and input fields are filled with firstname and
lastname
for(var i = countUsers; i > 0; i--) {
arr.push($F("username["+countUsers+"]"));
}
alert(arr);
> ,, <
I just tried to do this :
alert($F("username[1]")); and then it works !!!
So the problem could come from the type of iterator, should it be a
string...
Trying to force a string before passing the argument as below
var arr = [];
// countUser == 3 and input fields are filled with firstname and
lastname
for(var i = countUsers; i > 0; i--) {
var myCounter = new String(countUsers);
arr.push($F("username["+myCounter+"]"));
}
alert(arr); > SAME RESULT !
Javascript is a warm gun !
Any ideas ?
Thank you for your help !
