选项1 - * Backbone.js .事件 * -example

您可以在异步创建$el之后触发一个事件，如下所示：

app.view = Backbone.view.extend({
    initialize: function ()
    {
        // async setup the $el and then do the following after it is created
        this.trigger('el:created', this.$el);
    }
});

然后，所有其他视图都可以侦听此事件并相应地执行操作：

app.anotherView = Backbone.view.extend({
    initialize: function ()
    {
        var otherView = new app.view();

        // Only fires once so only listen once
        this.listenToOnce(otherView, 'el:created', this.createEl);
    },

    createEl: function ($el)
    {
        //do something with $el here
    }
});

选项2 - *jQuery.延迟 * -example

app.view = Backbone.view.extend({
    initialize: function ()
    {
        this.elCreation = $.Deferred();

        // async setup the $el and then do the following after it is created
        this.elCreation.resolve(this.$el);
    }
});

new app.view().elCreation.done(function($el)
{
    //do something with $el here
});
