我尝试让mixin“记住”它正在生成的选择器,这样我就可以在最后制作一个批量选择器。
为了说明我想要做什么 - 我的mixin看起来像这样:
@mixin fontcustom($name) {
@if $name == "heart" {
$glyph: '\2764'; // a special character in my own font -> ❤
}
@else if $name == "foo" { ... }
@else if $name == "bar" { ... }
@else if $name == "baz" { ... }
// ... much much more characters ...
&:before {
content:"#{$glyph}";
}
/* aggreagation of selectors ? */
}
@function selectorsUsingFontcustom() {
/* this should somehow result in a list of selectors, see above */
font-family: fontcustom;
color: red;
/* ... */
}
显然还需要更多样式声明,例如font-family,colors等。
我想避免重复声明所以我的问题是:有没有办法让mixin“记住”导致应用它的选择器并生成逗号分隔的列表,这导致类似下面的内容?
SCSS:
#my-fancy-selector [data-is-liked] {
@include fontcustom("heart");
}
.another>.fancy+.foo-selector {
@include fontcustom("foo");
}
.another>.fancy+.baz-selector {
@include fontcustom("baz");
}
/* no clue about the following: */
selectorsUsingFontcustom();
CSS:
#my-fancy-selector [data-is-liked]:before {
content:"\2764";
}
.another>.fancy+.foo-selector:before {
content:"\2765";
}
.another>.fancy+.baz-selector:before {
content:"\2767";
}
/* selectorsUsingFontcustom() should return sth like the following then: */
#my-fancy-selector [data-is-liked]:before,
.another>.fancy+.foo-selector:before,
.another>.fancy+.baz-selector:before {
font-family: fontcustom;
color: red;
/* ... */
}
有什么想法吗?

将@extend
与占位符选择器一起使用,如下所示:
%heart {
color: red;
}
h1 {
@extend %heart;
font-size: 3em;
}
h2 {
@extend %heart;
font-size: 2em;
}
li {
@extend %heart;
text-decoration: strikethrough;
}
输出:
h1, h2, li {
color: red;
}
h1 {
font-size: 3em;
}
h2 {
font-size: 2em;
}
li {
text-decoration: strikethrough;
}
