在AngularJS中，如何让一个工厂函数引用另一个？

For example, in the following code I would like func2 to call func1.

例如,在下面的代码中,我希望func2调用func1。

App.factory("MyLib", function() {

  return {

    func1: function() {
      console.log("func1");
    },

    func2: function() {
      func1();
    }

  }

});

How can I do this?

The safest way is to use the revealing module pattern:

最安全的方法是使用揭示模块模式:

App.factory("MyLib", function() {

    var func1 = function() {
        console.log("func1");
    };

    var func2 = function() {
        func1();
    };

    return {
        func1: func1,
        func2: func2
    };
});

I usually assign it to a variable name same as factory for easier reading and useful to reuse it when you have nested function as show in the example below.

我通常将它分配给与工厂相同的变量名称以便于阅读,并且当您具有嵌套函数时可以重复使用它,如下例所示。

App.factory("MyLib", function() {
    var MyLib = {
        func1: function() {
            console.log("func1");
        },
        func2: function() {
            MyLib.func1();
            angular.forEach(["1","2"], function(value, key) {
                //easier to read and understand
                MyLib.func1();
            },[]);
        }
    }
    return MyLib;
});
