Concatenate strings in Less
提问by juminoz
I think this is not possible, but I thought I ask in case there is a way. The idea is that I have a variable for path to web resource folder:
我认为这是不可能的,但我想我会问,以防万一。这个想法是我有一个用于网络资源文件夹路径的变量:
@root: "../img/";
@file: "test.css";
@url: @root@file;
.px {
background-image: url(@url);
}
I get this as a result:
我得到这个结果:
.px { background-image: url("../img/" "test.css"); }
But, I want the strings to combine into one string like this:
但是,我希望这些字符串像这样组合成一个字符串:
.px { background-image: url("../img/test.css"); }
Is it possible to concatenate strings together in Less?
是否可以在 Less 中将字符串连接在一起?

使用变量插值:
@url: "@{root}@{file}";
Full code:

@root: "../img/";
@file: "test.css";
@url: "@{root}@{file}";
.px{ background-image: url(@url); }

As you can see in the documentation, you can use string interpolation also with variable and plain strings together:
正如您在文档中所见,您还可以将字符串插值与变量和普通字符串一起使用:
@base-url: "http://assets.fnord.com";
background-image: url("@{base-url}/images/bg.png");

I was looking for the same trick for handling images. I used a mixin to answer this:
我正在寻找处理图像的相同技巧。我用一个 mixin 来回答这个问题:
.bg-img(@img-name,@color:"black"){
@base-path:~"./images/@{color}/";
background-image: url("@{base-path}@{img-name}");
}
Then you can use :
然后你可以使用:
.px{
.bg-img("dot.png");
}
or
或者
.px{
.bg-img("dot.png","red");
}

For those string-like unit values like 45deg
in transform: rotate(45deg)
use the unit(value, suffix)
function.
Example:
对于那些绳状部等的值45deg
中transform: rotate(45deg)
使用的unit(value, suffix)
功能。例子:
// Mixin
.rotate(@deg) {
@rotation: unit(@deg, deg);
-ms-transform: rotate(@rotation);
transform: rotate(@rotation);
}
// Usage
.rotate(45);
// Output
-ms-transform: rotate(45deg);
transform: rotate(45deg);
