SASS/SCSS对象键值循环 [英] SASS/SCSS object key value loop

问题描述

看看这个例子:

@include font-face('Entypo', font-files('entypo.woff'));

.icon {
  display: inline;
  font: 400 40px/40px Entypo;
}

.icon-star {
  @extend .icon;

  &:after {
    content: "\2605";
  }
}

.icon-lightning {
  @extend .icon;

  &:after {
    content: "\26A1";
  }
}

我想使事情变得尽可能干燥，所以我想知道以下情况是否可行，怎么办?

I want to make things as DRY as possible so I want to know if the following is possible, and if so how?

@include font-face('Entypo', font-files('entypo.woff'));

.icon {
  display: inline;
  font: 400 40px/40px Entypo;
}

$icons {
  $star: "\2605";
  $lightning: "\26A1";
}

@each $icon in $icons {
  $key = $icon{key}; // ???
  $value = $icon{value}; // ???

  .icon-#{$key} {
    @extend .icon;

    &:after {
      content: $value;
    }
  }
}

推荐答案

Sass当前不支持映射.您现在必须使用列表列表.

Sass does not currently support mappings. You'll have to live with lists of lists for now.

$icons: star "\2605", lightning "\26A1";

@each $icon in $icons {
  $key: nth($icon, 1);
  $value: nth($icon, 2);

  .icon-#{$key} {
    @extend .icon;

    &:after {
      content: $value;
    }
  }
}
