What's wrong with my JavaScript for loop, please.
I cannot get this to work or produce an error in firebug. Thanks.

What are you trying to do with the line:
for (var expected in errInput[j]) {
?
It's not working for sure, but I don't know what you're trying to do.
for (var expected in errInput[j]) {
?
It's not working for sure, but I don't know what you're trying to do.

I am trying to get this to print zero two three. Or print what ever happens to be in the array.
ASKER
Maybe if I remove:
for (var expected in errInput[j]) {
and put
switch (errInput) {
for (var expected in errInput[j]) {
and put
switch (errInput) {

Maybe I should of pointed out that I need the switch statement because depending on what is in the array, if just one item in the array it will just do one. If one and three are in the array it will do one and three.
case 'zero': do this;
case one': do this;
case 'two': do this;
case 'three': do this;
case 'zero': do this;
case one': do this;
case 'two': do this;
case 'three': do this;

Thanks. How do I make them get the words?

Sorry GeoffHarper. I did not see your post. Let me test your comment.

Thank all of you for your help.
errInput[0] = 'zero';
//errInput[1] = 'one';
errInput[2] = 'two';
errInput[3] = 'three';
same as :
errInput = ["zero", "two", "three"];
