如何在更少的时间内将属性名称作为参数传递给mixin [英] How to pass a property name as an argument to a mixin in less

问题描述

我想创建一个函数/混合器，如果它已经很暗，则它的颜色会变深，但是当它很亮时，它的颜色会变浅(归一化/极端化?)

I want to make a function/mixin that will make a color darker if it is already dark but lighter when it is light (normalize/extremeize?)

是否可以通过传递属性名称(颜色，背景颜色，右边框颜色等)来做到这一点?

Is it possible to do this by passing a property name (color, background-color, border-right-color, etc)?

.normalize(@color, @amount, @prop: "color") when (lightness(@color) >= 50%)
{
    @prop:lighten(@color, @amount);
}
.normalize(@color, @amount, @prop: "color") when (lightness(@color) < 50%)
{
    @prop:darken(@color, @amount);
}

推荐答案

目前，这是less.js github上的功能请求.因此，请在less.js 1.4 ..中注意这一点，直到您可以像这样入侵它...

This is currently a feature request on less.js github. So look out for it in less.js 1.4.. until then you can hack it like so...

.mixin(@prop, @value) {
    Ignore: ~"a;@{prop}:@{value}";
}

不太好，您会获得额外的财产，但这是目前的唯一方法.

Not very nice and you get an extra property but its the only way at the moment.
