Question

What is meant by Javascript error “Uncaught TypeError: Cannot call method ‘submit’ of undefined”?

I am trying to add an item to cart in my Magneto site. But it shows the above error. Can you point out its meaning or possible reason behind the error such that i can try deeper?

Answer 1

It is exactly as it says: you have an undefined value, and trying to call a method called submit on it, like this:

undefined.submit();

or like this:

var nonexistent;
nonexistent.submit();

or even like this:

var threeElementArray = [1, 2, 3];
threeElementArray[100].submit();

Why would a library raise it, I don’t know. You are not providing much details. It can either be a bug in their code, or more likely you’re giving it incorrect parameters somewhere.
