如何分离scss函数返回值
How to separate scss function returned values
我有两个 SCSS 映射调用 $my-map-1
和 $my-map-2
。每个地图都有带有十六进制值的键。我分别写了一个函数来 return 每个映射的键和十六进制值 ($key
, $value
)。
之后,我用我的函数写了一个@if
条件来检查地图。我将地图名称传递给函数。如果在那里映射,请检查 $key
是否等于给定名称。如果是,请将 $key
的 $valu
传递给我的颜色混合。这是我的代码。
$my-map-1: (
map-1-color-1: #506c89,
map-1-color-2: #737373,
map-1-color-3: #2a3949,
map-1-color-4: #182028,
);
$my-map-2: (
map-2-color-1: #fff,
map-2-color-2: #000,
map-2-color-3: #ddd,
map-2-color-4: #ccc,
);
//the function to read te map and return the key and the value.
@function color-map($color-map) {
@each $key, $value in $color-map {
@return ($key, $value);
}
}
//mixin
@mixin color-mix($color){
color: $color;
}
//css classes from here
@if color-map($my-map-1) {
if($key == map-1-color-1) {
.my-class{
@include color-mix($color:$value);
}
}
}
可以用map-get
方法,很有用:http://sass-lang.com/documentation/Sass/Script/Functions.html#map_get-instance_method
这是mixin的一个例子。我也将您的密钥作为参数传递:也许它更好,因为如果需要,您还可以检查其他密钥名称:
$my-map-1: (
map-1-color-1: #506c89,
map-1-color-2: #737373,
map-1-color-3: #2a3949,
map-1-color-4: #182028
);
$my-map-2: (
map-2-color-1: #fff,
map-2-color-2: #000,
map-2-color-3: #ddd,
map-2-color-4: #ccc
);
@mixin color-map($color-map, $key-map) {
@each $key, $value in $color-map {
@if($key == $key-map) {
.my-class{
color: map-get($color-map, $key);
}
}
}
}
@include color-map($my-map-1, map-1-color-1);
您的输出将是:
.my-class {
color: #506c89;
}
