模板引擎

特点

  1. 支持继承

  2. 支持包含子模板

  3. 支持golang原生模板语法(详细用法可参阅golang模板语法简明教程

  4. 自动注册模板函数 hasBlock(blocks ...string) boolhasAnyBlock(blocks ...string) bool

    • hasBlock(blocks ...string) bool - 是否在扩展模板中设置了指定名称的Block
    • hasAnyBlock(blocks ...string) bool - 是否在扩展模板中设置了指定名称中的任意一个Block
  5. 支持多重继承

模板继承

用于模板继承的标签有:Block、Extend、Super 例如,有以下两个模板:

  1. layout.html:
{{Block "title"}}-- powered by webx{{/Block}}
{{Block "body"}}内容{{/Block}}
  1. index.html:
{{Extend "layout"}}
{{Block "title"}}首页 {{Super}}{{/Block}}
{{Block "body"}}这是一个演示{{/Block}}

渲染模板index.html将会输出:

首页 -- powered by webx
这是一个演示

注意:

  1. Super标签只能在扩展模板(含Extend标签的模板)的Block标签内使用。
  2. Extend标签 必须放在页面内容的起始位置才有效

因为最新增加了对多重继承的支持,所以,现在我们还可以创建一个模板new.html用来继承上面的index.html,比如new.html的内容为:

{{Extend "index"}}
{{Block "body"}}这是一个多重继承的演示{{/Block}}

渲染这个新模板将会输出:

首页 -- powered by webx
这是一个多重继承的演示

也就是说这个新模板具有这样的继承关系:new.html -> index.html -> layout.html (目前限制为最多不超过10级)

包含子模板

例如,有以下两个模板:
footer.html:
	
	www.webx.top

index.html:

	前面的一些内容
	{{Include "footer"}}
	后面的一些内容
	
渲染模板index.html将会输出:

	前面的一些内容
	www.webx.top
	后面的一些内容
	
也可以在循环中包含子模板,例如:

	{{range .list}}
	{{Include "footer"}}
	{{end}}

因为本模板引擎缓存了模板对象,所以它并不会多次读取模板内容,在循环体内也能高效的工作。

Include标签也能在Block标签内部使用,例如:

	{{Block "body"}}
	这是一个演示
	{{Include "footer"}}
	{{/Block}}

另外,Include标签也支持嵌套。
