Question

我已经能够在我的牵线木偶控制器中触发事件：

 ...snip...
 var Controller = {};

_.extend(Controller, Backbone.Events);

// private
var Layout = Marionette.Layout.extend({
    template: _.template(layout),

    regions: {
        inspectorStart: "#inspector_start",
        loginStart:     "#login_start",
        playerStart:    "#player_start"
    }


});

// private
var _initializeLayout = function() {
    console.log('initialize Start Layout...');
    Controller.layout = new Layout();
    Controller.layout.on('show', function() {       **// This works**
        Controller.trigger('startLayout:rendered'); **// This works**
    });
    vent.trigger('app:show', Controller.layout); **// This works**

};


// Listen for events ///////////////////////////////////////////
// controller attach a sub view
Controller.on("startLayout:rendered", function() {  **// This works**
    console.log('startLayout:rendered =>StartController'); **// This works**
    // render views for the existing HTML in the template,...
    var inspectorStartView = new InspectorStartView();
    //  and attach it to the layout (i.e. don't double render)
    Controller.layout.inspectorStart.attachView(inspectorStartView);
    Controller.trigger('inspectorStart:show', inspectorStartView); **// This works**
...snip...

但是，当我尝试使用扩展牵线木偶ItemView时，我无法使事件或触发器起作用。

// views/InspectorStartView.js
// -------
define(["jquery", "marionette", "text!templates/InspectorStart.html"],

function($, marionette, template){

    var InspectorStartView = marionette.ItemView.extend({
       template: template,

        events: {
            'click .starting_thumbnail' : 'start'
            //'click #inspectorStart' : 'start' **// didn't work either**
        },
        //I had also tried triggers
        triggers: {
            //'click .starting_thumbnail' : 'inspectorStart:start'
            'click #inspectorStart' : 'inspectorStart:start' **// didn't work either**
        },


        start:function (){  **// Doesn't get called**
            console("Caught InspectorStartView click")
            this.trigger("inspectorStart:start")
        }

    });

    // Returns the View class
    return InspectorStartView;
});

以下是模板：

<!-- InspectorStart.html -->
<div id="inspectorStart" class="thumbnail starting_thumbnail">
<img src="/img/detective-97715888.jpg" alt="Inspector" width="200px" height="300px">
<div class="caption">
    <h3>Inspectors Enter Here</h3>
    <p>Den Masters, Teachers, Parents, House Mothers, this is where you start.</p>
</div>
</div>

我必须创建starting_thumbnail类，以便我得到一个指针：

.starting_thumbnail{
cursor: pointer;
}

我是否需要做其他事情才能使div可点击？

在我第一次尝试时，我在App.vent中传递并尝试使用它无济于事我正在使用_.extend（Controller，Backbone.Events）扩展Controller {};

根据@Ingro的一些调试建议，我记录了ItemView的$。el id。这个： console.log（[“InspectorStartView initalise”，这个。$ el]）

这是输出。有nodeName：“DIV”，localName是div。

当然上面是在initialize方法中。我想在创建一个'新'之后看到差异：

/ controller show inspector in the layout / subview
Controller.on('inspectorStart:show', function(inspectorStartView) {
    console.log('show inspector start view');
    console.log(**'InspectorVartView instance this.$el : ', inspectorStartView.el**);
    Controller.layout.inspectorStart.show(inspectorStartView);
});

输出要小得多：

InspectorVartView instance this.$el :  
<div>
   <!-- InspectorStart.html -->
   <div id="inspectorStart" class="thumbnail starting_thumbnail">…</div>
</div>

包含在div中的@Ingro为什么会这么重要？

有人看到我做错了什么吗？

谢谢，

原来我以某种方式破坏了jquery。我使用jsfiddle来证明我的代码是正确的。然后我开始查看版本号要求并替换了jquery，它开始工作。

感谢@Ingro的输入。
