Javascript 附加头不'；我不能在玉中工作

我的

布局.jade

如下：

doctype html
html
    head
        title= title
        link(rel='stylesheet', href='/stylesheets/style.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-grid.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-reboot.css')
        script(src="/javascripts/core.js")
        script(src="/javascripts/jquery.js")
        script(src="/javascripts/jquery-slim.js")
        script(src="/javascripts/bootstrap.js")
    body
        block content

extends layout

append head
    script(src="/javascripts/custom.js")
    ...

我的

位置。jade

如下：

doctype html
html
    head
        title= title
        link(rel='stylesheet', href='/stylesheets/style.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-grid.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-reboot.css')
        script(src="/javascripts/core.js")
        script(src="/javascripts/jquery.js")
        script(src="/javascripts/jquery-slim.js")
        script(src="/javascripts/bootstrap.js")
    body
        block content

extends layout

append head
    script(src="/javascripts/custom.js")
    ...

当我发球时，我明白了

这意味着附加根本不渲染

为什么？

Append仅适用于block，因此layout.jade的正确代码是

doctype html
html
    head
    block scripts
        title= title
        link(rel='stylesheet', href='/stylesheets/style.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-grid.css')
        link(rel='stylesheet', href='/stylesheets/bootstrap-reboot.css')
        script(src="/javascripts/core.js")
        script(src="/javascripts/jquery.js")
        script(src="/javascripts/jquery-slim.js")
        script(src="/javascripts/bootstrap.js")
    body
        block content

至于地点，翡翠将是

extends layout

append scripts
    script(src="/javascripts/custom.js")
    ...
