jquery - 如何在 CoffeeScript 中创建 jQuery 插件？

Question

关于How to Create a Basic Plugin有一个标题为保护 $ 别名并添加范围的部分。

The $ variable is very popular among JavaScript libraries, and if you're using another library with jQuery, you will have to make jQuery not use the $ with jQuery.noConflict(). However, this will break our plugin since it is written with the assumption that $ is an alias to the jQuery function. To work well with other plugins, and still use the jQuery $ alias, we need to put all of our code inside of an Immediately Invoked Function Expression, and then pass the function jQuery, and name the parameter $:

在 JavaScript 中，这个包装器看起来像这样:

(function ( $ ) {
  // do stuff
  return this;
})(jQuery)

如何将其翻译成 CoffeeScript？

Answer 1

这个 CoffeeScript :

$ = jQuery
### do stuff ###

编译为:

// Generated by CoffeeScript 1.6.3
(function() {
  var $;
  $ = jQuery;
  /* do stuff*/
}).call(this);

我认为效果是相同的，确保 $ 指向 jQuery，无论调用环境中的 $ 是什么。

这是Coffeescript的作者在Writing a jquery plugin in coffeescript - how to get "(function($)" and "(jQuery)"?中推荐的

为了更接近原始模式(do 对我来说仍然是一个黑匣子)

do ($=jQuery) ->
  ### do stuff  ###
  @

“裸”编译为:

// Generated by CoffeeScript 1.6.3
(function($) {
  /* do stuff*/

  return this;
})(jQuery);
