Question

我目前正在编写一个Backbone应用程序并且已经陷入了一个似乎非常简单的问题，但似乎无法解决它。

假设我有这样的观点（演示代码）

var View = Backbone.View.extend({
    initialize: function () {
         console.log('created a view');
    },
    events: {
         'click button':'buttonClicked',
         'click link':'linkClicked'
    },
    buttonClicked: function (event) {
         // I would like to store the event and pass this to the 
         // linkClicked function below when the linkClicked function is called 
         var $currentEvent = $(event.currentTarget);
    },
    linkClicked: function () {
         // When the link is clicked I would like to gain access to $currentEvent
    }
});

我想在单击链接时将变量$ currentEvent传递给linkClicked函数。最好将其存储在模型中，还是可以在视图周围传递变量。

对此的任何帮助都会很棒！

您可以这样做：

initialize: function () {
     /** Initialize the variable when View is first created. */
     this.currentEvent = 'something'; 
},
buttonClicked: function (event) {
     /** Assign variable when button is clicked. */
     this.currentEvent = $(event.currentTarget);
},
linkClicked: function () {
     /** Receive the value of the variable and output it. */
     console.log(this.currentEvent);
}
