我在这条线上收到错误 MyApp.trigger("some:event"); . 我从以下链接复制了代码

网址： http: //lostechies.com/derickbailey/2011/11/17/introduction-to-composite-javascript-apps/

你能帮我使用两个或更多的模块吗，每个模块都有多个视图。我需要像上面的 URL 那样使用骨干网与他们交流。

谢谢。

我试图以不同的方式解决这个问题，但最终还是得到了以下解决方案。解决方案包括在模块中编写我的代码，并使用木偶模块和发泄与它们进行通信。Marionette 帮了我很多，我希望这些不同的功能能在我的开发中进一步发展。

索引.html

<script type="text/javascript">
        $(function () {

            //var myModule = MyApp.module("MyModule");

           // console.log(MyApp.MyModule.someData); //=> public data

            MyApp.OrganizerModule.someFunction(); //=> public data

            //var LayOutModel = new MyApp.ShellModule.LayOut();

            var LayoutView = new MyApp.ShellModule.LayoutView();
            LayoutView.render();

            var Explorer = new MyApp.OrganizerModule.ExplorerView();

        });

    </script>

使用以下模板：

 <script id="layout_temp" type="text/template">
        <div id="layout"> 
              <div id="header">
            header
        </div>
        <div id="container">
            <div id="center" class="column">
                center
            </div>
            <div id="left" class="column">
                left
            </div>
            <div id="right" class="column">
                right
            </div>
        </div>
        <div id="footer">
            footer
        </div>
    </div>
    </script>
    <script id="Explorer" type="text/template">
       <div > start : 
       <button>Say hello</button>
       </div>
    </script>

这是模块定义和使用 Marionette 的事件订阅

MyApp.module("ShellModule", function (ShellModule, MyApp, Backbone, Marionette, $, _) {

    ShellModule.LayoutView = Backbone.View.extend({
        initialize: function () {
            //Backbone.ModelBinding.call(this);

            alert("Hello2");
            MyApp.vent.on("toolClick_Event", function (cat) {

                alert("test toolClick_Event fired");

            });
        }
        //    , events: {
        //        'toolClick_Event': 'toolClick_Event'
        //    }
     , render: function () {

         var template = _.template($("#layout_temp").html(), {});

         $("#Maincontainer").html(template);
         //$(this.el).append("<ul> <li>hello world</li> </ul>");
     }



    });

});

另一个使用 MyApp.vent.trigger 触发事件的模块。

MyApp.module("OrganizerModule", function (OrganizerModule, MyApp, Backbone, Marionette, $, _) {

    // Private Data And Functions
    // --------------------------

    var myData = "this is private data";

    var myFunction = function () {
        console.log(myData);
    }


    // Public Data And Functions
    // -------------------------

    OrganizerModule.someData = "public data";

    OrganizerModule.someFunction = function () {
        //console.log(MyModule.someData);
        alert(OrganizerModule.someData);
    }




    OrganizerModule.ExplorerView = Backbone.View.extend({

        el: "#center",
        events: {
            'click button': 'toolClick'
        }
    , initialize: function () {

        this.render();
        this.setElement(this.el);
    }
    , render: function () {

        var template = _.template($("#Explorer").html(), {});
        //this.$el.html.add(template);

        // $("#center").append(template);
        //return this.el;

        $(this.el).html(template);
        return this;

    }


    , toolClick: function () {
        alert("test toolClick");
        // var template = _.template($("#Explorer").html(), {});
        //$("#center").append(template);
        MyApp.vent.trigger('toolClick_Event');

        $("#Maincontainer").append("<div> other data </div>");
    }
    });

});

希望这对其他人有帮助。
