Backbone 1.1.0 视图 - 阅读选项 [英] Backbone 1.1.0 Views - Reading Options

问题描述

Backbone.js 1.1.0 的变更日志指出:

The changelog to Backbone.js 1.1.0 states:

主干视图不再自动附加作为 this.options 传递给构造函数的选项，但如果您愿意，您可以自己完成.

Backbone Views no longer automatically attach options passed to the constructor as this.options, but you can do it yourself if you prefer.

我的问题是我现在该怎么做?以前，我的视图中经常有 this.var = this.options.var.

My question is how can I do it now? previously, I had this.var = this.options.var regularly in my views.

推荐答案

如果您想访问传递的选项 - 只需保存它们:

If you want to access to passed options - just save them:

initialize: function (options) {
  this.options = options || {};
}

如果你使用 ES6:

initialize (options = {}) {
  this.options = options;
}

如果你想保存所有 Backbone.View 的传递选项，你可以像 ncksllvn 建议如下.

If you want to save passed options for all Backbone.View's you can override constructor like ncksllvn suggested below.
