翡翠之间的区别与封闭 [英] Difference between include and block in Jade

问题描述

在创建Jade模板时，块和使用include之间有什么区别？你什么时候使用另一个？

解决方案

块是占位符。其内容来自另一个玉器文件。
包含也是占位符。它的内容也来自另一个玉器文件。

到目前为止，两者都是平等的。

但是： p>

include嵌入一个完整的文件。包含文件定义要包括哪个文件。因此，包含对于外部部件（如页脚或标题）是很好的，它们总是以相同的方式加载。

块仅在顶部文件中定义占位符。包含哪些内容不是由此文件定义的，而是由子文件定义的。所以，控制所包含的内容正在被逆转。

有一个include，A说：Import B.
B有一个块，这里是内容对于占位符，请使用文件A及其占位符填写我的内容。

包含意味着自上而下，块意味着自下而上。

$另外，一个文件可能包含几个块。

何时使用什么：

• 通常在具有块的主页面中定义站点的总体布局。


• 单个页面包含每个单独文件的内容，参考主文件并填写其块。


• 正在使用包括设置主或页面中的子视图。

有帮助吗？

What is the the difference between blocks and using include when you are creating Jade templates? When do you use one over the other?

解决方案

A block is a placeholder. Its content comes from another jade file. An include is a placeholder, too. Its content also comes from another jade file.

So far, both are equal.

But:

include embeds a complete file. The including file defines which file is being included. Hence include is fine for outsourcing parts such as a footer or a header, which are always loaded the same way.

A block just defines a placeholder in the top file. Which content is included is not defined by this file, but by a sub-file. So, control over what is included is being reversed.

With an include, A says: Import B. With a block, B says: Here is content for a placeholder, and please use file A and its placeholders to fill in my content.

include means top-down, blocks mean bottom-up.

Additionally, one file may include several blocks.

When to use what:

• It's common to define the overall layout of a site in a master page with blocks.
• The single pages contain the content for each individual file, reference the master file and fill its blocks.
• Subviews in either the master or the page are being set up using includes.

Does that help?
