什么是JavaScript语法：{Ci，CC}？ [英] What is this JavaScript syntax: {Ci, CC}?

问题描述

  var {Cc， Ci} = require（'chrome'）; 
  

只要好奇那是什么语法，是否对FF开发或其他东西是特别的。

解决方案

请参阅Domenic关于什么语法称为解构赋值的解答。接下来的答案是为什么FF插件开发需要这样做。

有关于这是什么以及为什么在 http://groups.google.com/group/mozilla-labs-jetpack/browse_thread/thread / d288b79903b5b434 。

简短的回答是肯定的，它是针对Firefox附加开发的。相关的文档可以在 https://addons.mozilla.org/en-US/developers/docs/sdk/1.3/dev-guide/module-development/chrome.html 。

I'm doing some FF add-on development and I'm seeing syntax like this:

var {Cc, Ci} = require('chrome');

Just curious what that syntax is and if it's special to FF development or something else.

解决方案

See Domenic's answer as to what the syntax is which is called a destructuring assignment. The answer that follows is why this is needed for FF add-on development.

There's a discussion on what this is and why it is needed at http://groups.google.com/group/mozilla-labs-jetpack/browse_thread/thread/d288b79903b5b434.

Short answer is yes, it's specific for Firefox add-on development. The relevant documentation can be found at https://addons.mozilla.org/en-US/developers/docs/sdk/1.3/dev-guide/module-development/chrome.html.
