Pug – mixin与条件.json对象

我正在尝试使用条件(如果在外部.json中存在对象),但是帕格不会识别它.

所以,我的json文件是这样的:

{
  "portfolioItems": [object1: {
      objectA { ...
      },
      objectB { ...
      },
      "buttons": [{
        key: value
      }, {
        key: value
      }]
    }, object2: {
      objectA { ...
      },
      objectB { ...
      }], object3: {
      objectA { ...
      },
      objectB { ...
      }
    }
  }
}

基本上,我需要为“对象1”(按钮)创建一个额外的div.

mixin portfolio(css, image, title, description)
    div(class= "item " + css)
        .wrap-img
            img(src= assets + "img/home/" + image)&attributes(attributes)
        .wrap-text
            h3= title
            p= description
            if home.portfolioItems.buttons
                div.buttons
                    each val in home.portfolioItems.buttons
                        a(href= val.link, target="_blank")
                            img(class= val.className, src= assets + "img/stores/" + val.image)

div.portfolio--items
            - var projects = home.portfolioItems;
            each item in projects
                +portfolio(item.class, item.image, item.title[lang], item.description[lang])(alt= item.title[lang], title=item.title[lang])

帕格可以访问“home.portfolioItems.buttons”,但它不能在mixin中进行条件化?因为我可以在外面运行它(但我不想要它).

提前致谢.对不起英文错误. 😉

最佳答案 Mixins有自己的范围,因此您需要在对象中传递它们.我还建议使用单个选项对象,这比跟踪单独的参数要容易得多,与顺序无关,并且更具可读性.

请注意,您可以使用定义调用mixin并跨越多行

+portfolio({
  "css": "css",
  "image": "image",
  "title": "title",
  "description": "description",
  "items": portfolioItems
})

这就是mixin的样子:

mixin portfolio(options)
  div(class= "item " + options.css)
    .wrap-img
      img(src= assets + "img/home/" + options.image)&attributes(options.attributes)
    .wrap-text
      h3= options.title
      p= options.description
      if options.items.buttons
        div.buttons
          each val in options.items.buttons
            a(href= val.link, target="_blank")
              img(class= val.className, src= assets + "img/stores/" + val.image)

如果portfolioItems中不存在buttons属性,您还可以避免传入所有项目并传入按钮或空数组:

+portfolio({
  "css": "css",
  "image": "image",
  "title": "title",
  "description": "description",
  "buttons": portfolioItems.buttons || []
})

这将避免需要条件测试,因为你保证在mixin中至少有一个空数组:

mixin portfolio(options)
  div(class= "item " + options.css)
    .wrap-img
      img(src= assets + "img/home/" + options.image)&attributes(options.attributes)
    .wrap-text
      h3= options.title
      p= options.description
      div.buttons
        each val in options.buttons
          a(href= val.link, target="_blank")
            img(class= val.className, src= assets + "img/stores/" + val.image)
