我在SAS的嵌套方面遇到了多项选择的问题,对它有很多看法,我希望你能帮助我并理解(因为我的英文写得不是很好)。
SASS mixin:
@mixin data($x) {
$sel: &;
$collector: ();
@for $i from 1 through length($sel) {
$s: nth($sel, $i);
$last: nth($s, -1);
@if str-slice($last, -1) == "]" {
// if is just the bare attribute with no value, $offset will be -1, otherwise it will be -2
$offset: -1;
$current-x: $x;
@if str-slice($last, -2) == '"]' {
// this attribute already has a value, so we need to adjust the offset
$offset: -2;
} @else {
// no attribute value, so add the equals and quotes
$current-x: '="' + $x + '"';
}
$last: str-slice($last, 1, $offset - 1) + $current-x + str-slice($last, $offset);
$collector: append($collector, set-nth($s, -1, $last), comma);
} @else {
// following line will append $x to your non-attribute selector
$collector: append($collector, selector-append($s, $x), comma);
// the following line will not change your non-attribute selector at all
//$collector: append($collector, $s, comma);
}
}
@at-root #{$collector} {
@content;
}
}
SASS:
[data-content] {
@include data("content") {
background: black;
}
}
输出:
[data-content="content"] {
background: black;
}
问题是我不能嵌套多个项目,例如不起作用:
[data-content] {
@include data("content", "menu") {
background: black;
}
}
输出:
[data-content="content"],
[data-content="menu"] {
background: black;
}
有什么方法可以解决吗?
答案 0 :(得分:0)
如果您不介意指定选择器而不是将它们作为变量传递,您可以随时执行此类操作。
[data-content="content"], [data-content="menu"]{
@include data() {
background: black;
}
}
