我想从特定$lists
(在这种情况下为$map
的每个$value-tree
中调用所有值,并为该数字创建媒体查询。
$map
的内容如下:
$breakpoints: (
564
768
992
1200
);
$value-tree: (
width: (
80%, 70%, 400px, 500px
),
font-size: (
20px, 30px, 40px, 50px
),
color: (
lightblue, orange, lime, crimson
),
border: (
1px solid black,
4px solid orange,
7px solid brown,
10px solid lightblue
)
);
这是我的代码:
@mixin media-module($prefix, $properties...) {
@each $names, $value in $properties {
$myValue: map-get($names, $value);
$myGrid: nth($breakpoints, $myValue);
// doesn't work
@media all and (min-width: $myGrid + px) {
@each $names in $properties {
#{$names}: 123;
}
}
}
}
主要问题是 map-get 和 map-values 这两个指令无法从$values
调用$lists
。
使用map-get指令来调用$values
:
错误:$ map:“ width”不是“ map-get”的地图 在scss / app.scss的第112行上的“媒体模块”中
使用的地图值:
错误:$ map:“宽度”不是“ map-values”的地图
是否有任何方法可以从$lists
内部的$map
获取或调用值?
非常感谢。
===============更新12/6 ===============
我可以为每个$breakpoints'
值创建媒体查询数量,但是它仅调用width的值,如下所示:
@media all and (min-width: 564px) {
.qaz {
width: 80%;
display: 80%;
border: 80%; } }
@media all and (min-width: 768px) {
.qaz {
width: 70%;
display: 70%;
border: 70%; } }
@media all and (min-width: 992px) {
.qaz {
width: 400px;
display: 400px;
border: 400px; } }
@media all and (min-width: 1200px) {
.qaz {
width: 500px;
display: 500px;
border: 500px; } }
第二个代码如下:
@mixin mqg3($prefix, $properties...) {
@each $contents, $dummy in $prefix, $properties {
$myGroup: map-get($prefix, $contents);
@each $values in $myGroup {
$myIndex: index($myGroup, $values);
$myGrid: nth($breakpoints, $myIndex);
@media all and (min-width: $myGrid + px) {
@each $names in $properties {
#{$names}: $values;
}
}
}
}
}
PS
感谢@Jakob回答我,但我想让$properties
可以在@include
内部进行检查,因此用户无需每次向上滚动来检查{{ 1}}:
.qaz {@include mqg3($ bp-values,width,display,border); }

我认为您想要这样的东西
SCSS
@mixin media-module {
$index: 1;
@each $bp in $breakpoints {
@media all and (min-width: $bp * 1px){
@each $key, $list in $value-tree {
#{$key}: nth($list, $index);
}
$index: $index + 1;
}
}
}
.class {
@include media-module;
}
CSS输出
@media all and (min-width: 564px) {
.class {
width: 80%;
font-size: 20px;
color: lightblue;
border: 1px solid black;
}
}
@media all and (min-width: 768px) {
.class {
width: 70%;
font-size: 30px;
color: orange;
border: 4px solid orange;
}
}
@media all and (min-width: 992px) {
.class {
width: 400px;
font-size: 40px;
color: lime;
border: 7px solid brown;
}
}
@media all and (min-width: 1200px) {
.class {
width: 500px;
font-size: 50px;
color: crimson;
border: 10px solid lightblue;
}
}

正如我在这篇帖子中试图说的:How to get $values of Array in SCSS?,我认为嵌套地图可以帮助您找到更清晰,更简单的解决方案:
$bp-values:(
xs:(
display: 564px,
width: 200px,
font-size: 20px,
color:lightblue,
border:1px solid black
),
md:(
display: 768px,
width: 300px,
font-size: 30px,
color:orange,
border:4px solid orange
),
lg:(
display: 992px,
width: 400px,
font-size: 40px,
color:lime,
border:7px solid brown
),
xl:(
display: 1200px,
width: 500px,
font-size: 50px,
color:crimson,
border:10px solid lightblue
)
);
@mixin mqg3($map, $keys...) {
@each $keyMap, $valueMap in $map {
@media all and (min-width: map-get($valueMap, display)) {
@each $v in $keys {
#{$v}: map-get($valueMap, $v);
}
}
}
}
每个相关性都更清楚。不必要在您的参数中插入display
,因为我想这是您的最小宽度:
.qaz { @include mqg3($bp-values, width, border); }
.qaz1 { @include mqg3($bp-values, color, font-size); }
这是结果:
@media all and (min-width: 564px) {
.qaz {
width: 200px;
border: 1px solid black;
}
}
@media all and (min-width: 768px) {
.qaz {
width: 300px;
border: 4px solid orange;
}
}
@media all and (min-width: 992px) {
.qaz {
width: 400px;
border: 7px solid brown;
}
}
@media all and (min-width: 1200px) {
.qaz {
width: 500px;
border: 10px solid lightblue;
}
}
@media all and (min-width: 564px) {
.qaz1 {
color: lightblue;
font-size: 20px;
}
}
@media all and (min-width: 768px) {
.qaz1 {
color: orange;
font-size: 30px;
}
}
@media all and (min-width: 992px) {
.qaz1 {
color: lime;
font-size: 40px;
}
}
@media all and (min-width: 1200px) {
.qaz1 {
color: crimson;
font-size: 50px;
}
}
编辑1
正如您在评论中询问的那样,如果要使用列表,这是另一种解决方案。我将您的$breakpoints
与其他列表放在一起。您可以将args中的display
删除,因为默认情况下,我始终将其用作min-width
:
$value-tree: (
display:(
564, 768, 992, 1200
),
width: (
80%, 70%, 400px, 500px
),
font-size: (
20px, 30px, 40px, 50px
),
color: (
lightblue, orange, lime, crimson
),
border: (
1px solid black,
4px solid orange,
7px solid brown,
10px solid lightblue
)
);
@mixin mqg3($map, $keys...){
$myList:map-get($map, display);
@each $myItem in $myList {
$i: index($myList, $myItem);
@media all and (min-width: $myItem * 1px) {
@each $v in $keys {
#{$v}: nth(map-get($value-tree, $v), $i);
}
}
}
}
.qaz { @include mqg3($value-tree, width, border); }
这是输出:
@media all and (min-width: 564px) {
.qaz {
width: 80%;
border: 1px solid black;
}
}
@media all and (min-width: 768px) {
.qaz {
width: 70%;
border: 4px solid orange;
}
}
@media all and (min-width: 992px) {
.qaz {
width: 400px;
border: 7px solid brown;
}
}
@media all and (min-width: 1200px) {
.qaz {
width: 500px;
border: 10px solid lightblue;
}
}
