MarionetteJS:应用程序区域与布局

MarionetteJS: Application Regions vs. Layouts

我正在阅读最新版本 (2.3.0) 的文档,它说应用程序区域现在已被弃用。

Application Regions

Warning: deprecated This feature is deprecated. Instead of using the Application as the root of your view tree, you should use a Layout View. To scope your Layout View to the entire document, you could set its el to 'body'. This might look something like the following: var RootView = Marionette.LayoutView.extend({ el: 'body' });

在大多数教程中,包括 David Sulc 的书 Backbone Marionette:A Gentle Introduction,它使用以下代码片段向应用程序添加区域。

下面的示例使用 addRegions,我应该怎么做?

var ContactManager = new Marionette.Application({});
ContactManager.addRegions({
    mainRegion: "#main-region"
});

var ContactView = Marionette.ItemView.extend({
    template: "#whatever",
    ui: {
        button: ".button".
    },
    events: {
        "click @ui.button": "click",
    },
    click: function () {
        console.log("do stuff here...");
    }
});

ContactManager.on("start", function () {
    var contactView = new ContactView({
        model: someModel
    });
    ContactManager.mainRegion.show(contactView);
});

改用布局视图。

例如您可以这样做:

var ContactManager = new Marionette.Application({});
var LayoutView = Backbone.Marionette.LayoutView.extend({
  template: "#layout-view-template",

  regions: {
    menu: "#menu",
    content: "#content"
  }
});

ContactManager.layout_view = new LayoutView(); 
ContactManager.layout_view.render(); 

我从来没有直接将区域添加到我的应用程序对象。
