是否函數同名覆蓋，建議單獨命名空間，例如：

var?scope1?=?(function()?{
????//?your?function
????var?fun1?=?function()?{};
????return?{
????????fun1?:?fun1
????}
})();

var?scope2?=?(function(){
????//?your?function2
????var?fun2?=?function()?{};
????//?some?variable
????var?a,?b,?c
????return?{
????????fun2?:?fun2,?
????????a?:?a,
????????b?:?b
????????//...
????};
})();

//?調用
scope1.fun1();
scope2.fun2();
scope2.a;
