Is there a way to wrap all JavaScript methods with a function?

Question

I want to wrap every function call with some logging code. Something that would produce output like:

func1(param1, param2)
func2(param1)
func3()
func4(param         


        

Answer 1

Maybe you could have a function to which you pass the function to execute as a parameter:

function runner(func_to_run) {
    alert('about to run ' + func_to_run.name);

    func_to_run();

}

function test() {
    alert ('in test');
}

runner(test)
