Sass map.get()不起作用.map-get()可以.是什么赋予了? [英] Sass map.get() doesn't work. map-get() does. What gives?
问题描述
我建立了一个颜色值映射表,并创建了一个简单的函数来检索它们.
I set up a map of color values and created a simple function to retrieve them.
在进行检索时,我遵循了 Sass文档,该文档指出您可以进行检索使用 map.get()
函数的地图值.使用此代码或任何其他 map.function
会导致错误:没有名称空间为"map"的模块.
.
While doing the retrieval, I followed the Sass documentation which states that you can retrieve a map value using the map.get()
function. Using this or any other map.function
results in an Error: There is no module with the namespace "map".
.
在检查地图模块时,我注意到了一种可行的替代语法 map-get()
.
Checking out the map module, I noticed an alternative syntax, map-get()
, which does work.
有什么作用?我是否缺少某些东西,例如导入地图模块,以便可以这种形式使用它?
What gives? Am I missing something, like importing the map module, so that I can use it in that form?
在下面查看我的代码:
// Using npm dart `sass 1.26.11`.
$colors: ('primary': black, 'secondary': white);
// Doesn't work
@function color($color) {
@return map.get($colors, $color);
}
// Does work
@function color($color) {
@return map-get($colors, $color);
}
问题:为了使 map.get()
语法起作用,我需要更改什么?
Question: What do I need to change to get the map.get()
syntax to work?
推荐答案
我遇到了与OP类似的问题(使用dart-sass v1.25.0),并且只有 map-get
有效, map.get
不会.
I am having a similar issue as OP (using dart-sass v1.25.0), and only map-get
works, map.get
doesn't.
The documentation doesn't seem to be very clear on this, but the (Sass Module System: Draft 6) document on Github explains it better.
似乎 Sass正在继续使用以使用 @use
支持 @import
,以便与本机CSS更好地兼容,并且为了获得对 map.get
的访问权限,您现在必须显式导入 map模块
使用 @use
关键字.
It seems like Sass is moving on to using @use
in favour of @import
for better compatibility with native CSS, and in order to get access to map.get
you now must explicitly import the map module
using the @use
keyword.
@use "sass:map";
$colors: ('primary': black, 'secondary': white);
@function color($color) {
@return map.get($colors, $color);
}
