如何在泛型jquery ajax调用中构造和调用方法或函数

I'm trying to construct a generic Ajax function by passing the few properties required by a jQuery Ajax object as object parameters. I'm stuck on one piece of the puzzle, that is the proper way to pass the callback function within "done". The idea is to replace about 10 ajax functions in my .js file with just one ajax function.I'm trying to construct a generic Ajax function
