如何使用requirejs加载koLite?

问题描述

这是来自tickout.dirtyFlag.js

This is from knockout.dirtyFlag.js

;(function (ko) {
        ko.DirtyFlag = function (objectToTrack, isInitiallyDirty, hashFunction) {

            hashFunction = hashFunction || ko.toJSON;

            var
                _objectToTrack = objectToTrack,
                _lastCleanState = ko.observable(hashFunction(_objectToTrack)),
                _isInitiallyDirty = ko.observable(isInitiallyDirty),

                result = function () {
                    var self = this;

                    self.isDirty = ko.computed(function () {
                        return _isInitiallyDirty() || hashFunction(_objectToTrack) !== _lastCleanState();
                    });

                    self.reset = function () {
                        _lastCleanState(hashFunction(_objectToTrack));
                        _isInitiallyDirty(false);
                    };

                    return self;
                };

            return result;
        };
    })(ko);

在我的模型中，我有一个这样的定义设置:

In my model I have a define setup like this:

define([
    "lib/knockout",
    "lib/knockout.dirtyFlag"
],
function(ko) {
...
  self.dirtyFlag = new ko.DirtyFlag([
}

基本上，我得到一个错误，指出DirtyFlag是未定义的.

basically I get an error saying that DirtyFlag is undefined.

我该怎么办?

推荐答案

好吧，看来我已经开始工作了，所以我将发布我的发现:

Well, looks like I got it working, so I'll post my findings:

在我的requirejs配置中，我添加了以下内容:

In my requirejs config I added this:

shim: {
"lib/knockout/knockout.dirtyFlag": {
    deps: [
        "lib/knockout/knockout"
    ],
    init: function (ko) {
        var self = this;
        ko.DirtyFlag = self.ko.DirtyFlag;
        return ko;
    }
}

我对javascript或requirejs不太熟悉，但是init似乎将dep放在"ko"中，然后就可以在ko上创建一个DirtyFlag. self.ko.DirtyFlag是实际的kickout.dirtyFlag javascript.

I'm not very familiar with javascript or requirejs, but init seems to put the dep in "ko" and then I am able to create a DirtyFlag on ko. self.ko.DirtyFlag is the actual knockout.dirtyFlag javascript.
