如何动态生成用逗号分隔的类列表? [英] How to dynamically generate a list of classes with commas separating them?

问题描述

我正在使用SASS的SCSS语法来创建动态网格系统，但是遇到了麻烦.

I'm working with the SCSS syntax of SASS to create a dynamic grid system but I've hit a snag.

我正在尝试使网格系统完全动态:

I'm trying to make the grid system completely dynamic like this:

$columns: 12;

然后我创建像这样的列:

then I create the columns like this:

@mixin col-x {
  @for $i from 1 through $columns {
  .col-#{$i} { width: $column-size * $i; }
  }
}

哪个输出:

.col-1 {
    width: 4.16667%;
  }

.col-2 {
    width: 8.33333%;
}
etc...

这很好用，但是接下来我要做的是根据所选择的$ columns的数目动态生成一列由逗号分隔的长列类-例如，我希望它看起来像这样:

This works well but what I want to do next is dynamically generate a long list of column classes separated by commas based on the number of $columns chosen - e.g I want it to look like this:

.col-1,
.col-2,
.col-3,
.col-4,
 etc... {
float: left;
}

我已经厌倦了:

@mixin col-x-list {
  @for $i from 1 through $columns - 1 {
  .col-#{$i}-m { float: left; }
  }
}

但是输出是这样的:

.col-1 {
  float: left;
}
.col-2 {
  float: left;
}
etc...

我对这里的逻辑以及创建这样的东西所需的SCSS语法有些困惑.

I'm a little stuck on the logic here as well as the SCSS syntax required to create something like this.

有人有什么想法吗?

推荐答案

我认为您可能想看看 @extend .如果您将其设置为:

I think you may want to take a look at @extend. If you set that up something like:

$columns: 12;

%float-styles {
  float: left;
}

@mixin col-x-list {
  @for $i from 1 through $columns {
      .col-#{$i}-m { @extend %float-styles; }
  }
}

@include col-x-list;

它应该在您的css文件中呈现为:

It should render in your css file as:

.col-1-m, .col-2-m, .col-3-m, .col-4-m, .col-5-m, .col-6-m, .col-7-m, .col-8-m, .col-9-m, .col-10-m, .col-11-m, .col-12-m {
  float: left;
}

在文档中

@extend .
