问题描述

我目前正在将网格翻译为LESS,但我似乎无法找出字符串插值。



这里是帮助类,应该生成所有的列:

  .createColumns(@ colNumber + 1){} 

.createColumns(@index)when (@index< @colNumber){
(〜.col @ {index}){
width:@baseWidth * @index;
}

.createColumns(@index + 1);
}

.createColumns(01);问题是,我收到一个错误,说这是错误的这个部分

〜.col @ {index})



以下是错误讯息:

  ParseError:无法识别的输入
在第17行第4列的grid.css中:
16 .createColumns(@index)when(@index< @colNumber ){
17(〜.col @ {index}){
18 width:@baseWidth * @index;

我已经检查了几个例子,并且都使用相同的语法,所以我不知道失踪。
这也是我的一个尝试,导致一个错误:

  .createColumns(@index)when index< @colNumber){
@class:col@index;
。(@ class){
width:@baseWidth * @index;
}
.createColumns(@index + 1);
}


解决方案

1.4.x,使用

  .col @ {index} {
width:@baseWidth * @index;
}


I am currently translating my grid into LESS, but I can't seem to figure out string interpolation.

Here's helper class that is supposed to generate all my columns:

.createColumns (@colNumber+1) {}

.createColumns (@index) when (@index < @colNumber) {
    (~".col@{index}") {
         width: @baseWidth * @index;
    }

    .createColumns (@index + 1);
}

.createColumns (01);

Problem is, I get error that says something is wrong with this part (~".col@{index}").

Here's the error message:

ParseError: Unrecognised input
in grid.css on line 17, column 4:
16    .createColumns (@index) when (@index < @colNumber) {
17        (~".col@{index}") {
18            width: @baseWidth * @index;

I have checked several examples and all use same syntax, so I'm not sure what I'm missing. This was also one of my tries that resulted in an error:

.createColumns (@index) when (@index < @colNumber) {
    @class : "col"@index;
    .(@class) {
        width: @baseWidth * @index;
    }
.createColumns (@index + 1);
}

解决方案

Escaped selector interpolation is deprecated in 1.4.x, use

.col@{index} {
     width: @baseWidth * @index;
}

instead.
