javascript - Backbone js 如何与 css 选择器交互？

Question

我刚刚开始学习 Backbone js。几分钟后，我阅读了相当复杂的示例，但我不明白Backbone 模型如何与 DOM 选择器交互？

Answer 1

在 Backbone.js 中，模型根本不应该与 View 层交互。

另一方面， View 应该表示 View 中的模型更改，但 Backbone.js 没有对 DOM 操作、模板、CSS 等的任何内置支持:

Backbone is agnostic with respect to your preferred method of HTML templating. Your render function could even munge together an HTML string, or use document.createElement to generate a DOM tree. However, we suggest choosing a nice JavaScript templating library. Mustache.js, Haml-js, and Eco are all fine alternatives. Because Underscore.js is already on the page, _.template is available, and is an excellent choice if you've already XSS-sanitized your interpolated data.
