javascriptmvc - JavaScriptMVC框架中Controller和Class的问题

Question

$.Controller("Whiteboard", {}, {
    init: function(){
        var pen = new Pen();
    },
    sendRequest: function() {
        // This function should listen draw/erasing events from Pen
    }

});
$.Class("Pen",{},{

    init: function() {
        // Pen setup, click to draw etc..
    }
});

像这样，我想要 Pen 的白板监听事件，我该怎么做？我需要控制器监听一个类。

如果这是 JMVC 3.2+，您可以执行以下操作：

$('.whiteboard').whiteboard({pen:new Pen()});

$.Controller("Whiteboard", {}, {
    "{pen} draw": function() {
        this.sendRequest();
    }
});

$.Observe('Pen',{},{
    draw: function() {
        $(this).triggerHandler('draw');
    }
});

对于 JMVC 3.1，您必须像这样在控制器中使用$.Model而不是$.Observe使用：this.bind

$.Controller("Whiteboard", {}, {
    init: function() {
        this.bind(this.options.pen,'draw',this.callback('sendRequest'));
    }
});
