Can I catch a JavaScript error that my code did not throw?

Question

So I have some code that I cannot edit that sometimes errors out due to various reason I cannot control. This can be a failed ajax call (non-jQuery) or simply a function that fails. Is there any way I can do a generic JS error catch (I do use jQuery) if I do not have access to the code that generates them?

Try with onerror

window.onerror = function() {
    alert("error");
};
