Mozilla expression _ noSuchMethod ___ javascript skills

This is a special method, but it has great significance. But unfortunately, only firefox supports it. A simple example explains its usefulness.

The Code is as follows:

// It can only be run in firefox
Var test = {
Name: "puterjam ",
_ NoSuchMethod __: function (name, args ){
Alert (["Your call an error function [", name, "]. Arguments list: [", args, "]"]. join (""));
}
}
Test. hello ();
Test. helloWorld ("china", "shenzhen ");

When we execute an unspecified method in the test object, the _ noSuchMethod _ method is automatically executed, so that we can use it for fault tolerance and monitoring.
