Backbone.js的是否有jQuery的硬依赖？ [英] Does Backbone.js have a hard dependency on jQuery?
问题描述
据骨干JS网站：
主干的只能硬依赖是Underscore.js（> 1.3.1）。对于REST风格的持久性，历史支持通过Backbone.Router和DOM操作与Backbone.View，包括json2.js，无论是与jQuery的（1.4.2）或的Zepto。
Backbone's only hard dependency is Underscore.js ( > 1.3.1). For RESTful persistence, history support via Backbone.Router and DOM manipulation with Backbone.View, include json2.js, and either jQuery (1.4.2) or Zepto.
我code测试下方，去除jQuery和骨干视图抛出一个错误。
I tested with code below, removing jQuery and the Backbone view throws an error.
<html>
<head>
<title>asda</title>
<!--<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>-->
<script src="http://documentcloud.github.com/underscore/underscore.js"></script>
<script src="http://documentcloud.github.com/backbone/backbone.js"></script>
<script type="text/javascript" charset="utf-8" async defer>
SearchView = Backbone.View.extend({
initialize: function(){
alert("Alerts suck.");
}
});
// The initialize function is always called when instantiating a Backbone View.
// Consider it the constructor of the class.
var search_view = new SearchView;
</script>
</head>
<body>
</body>
</html>
哪有没有jQuery的Backbone.View和Backbone.Router工作？
How can Backbone.View and Backbone.Router work without jQuery?
推荐答案
虽然Backbone.View不依赖于的在的DOM操作库，即你不能使用JavaScript未在有组织的香草某种类型的库中，可以配置骨干用自己喜欢的任意库。
While Backbone.View does depend on a DOM manipulation library, ie you can't use vanilla javascript that is not organized in to a library of some sort, you can configure Backbone to use whatever library you'd like.
请参阅从骨干源如下：
// Set the JavaScript library that will be used for DOM manipulation and
// Ajax calls (a.k.a. the `$` variable). By default Backbone will use: jQuery,
// Zepto, or Ender; but the `setDomLibrary()` method lets you inject an
// alternate JavaScript library (or a mock library for testing your views
// outside of a browser).
Backbone.setDomLibrary = function(lib) {
$ = lib;
};
调用此方法将允许你使用任何你想要的库。
Calling this method will allow you to use whatever library you want.
例如：
Backbone.setDomLibrary(myCustomLibrary);
