未加引号的字符串上的 SASS“错误：$color：不是颜色”

问题描述

我使用 gulp-sass-variables 将变量传递给 sass，它总是会注入一个字符串。

取消引用似乎对我的字符串没有任何影响。

$primary: "#ffffff"; // <- Passed in via gulp-sass-variables

$anchor: scale-color(unquote($primary),$lightness: -14%); // Error: $color: #ffffff is not a color.

我是否以错误的方式使用了 unquote？

解决方法

您不需要使用取消引号，只需从颜色中删除双引号即可

$primary: #ffffff; 
$anchor: scale-color($primary,$lightness: -14%);

你可以试试下面的代码并检查它是否有效：

// Thanks Hugo for convert string to number function

// Thanks @roshanakjamali

// remove space from string
@function str-replace($string,$search,$replace) {
  $index: str-index($string,$search);

  @if $index {
    @return str-slice($string,1,$index - 1) + $replace +
      str-replace(
        str-slice($string,$index + str-length($search)),$replace
      );
  }

  @return $string;
}

// convert string to list
@function str-split($string,$separator) {
  $split-arr: ();
  $index: str-index($string,$separator);
  @while $index != null {
    $item: str-slice($string,$index - 1);
    $split-arr: append($split-arr,unquote($item));
    $string: str-slice($string,$index + 1);
    $index: str-index($string,$separator);
  }
  $split-arr: append($split-arr,unquote($string));
  @return $split-arr;
}

// convert string to number
@function number($string) {
  // Matrices
  $strings: "0" "1" "2" "3" "4" "5" "6" "7" "8" "9";
  $numbers: 0 1 2 3 4 5 6 7 8 9;

  // Result
  $result: 0;

  // Looping through all characters
  @for $i from 1 through str-length($string) {
    $character: str-slice($string,$i,$i);
    $index: index($strings,$character);

    @if not $index {
      @return false;
    }

    $number: nth($numbers,$index);
    $result: $result * 10 + $number;
  }

  @return $result;
}

@function convertStringToColor($colors) {
  $string: str-replace($colors," ","");
  $list: str-split($string,",");
  $red: nth($list,1);
  $green: nth($list,2);
  $blue: nth($list,3);

  $rgb: rgb(number($red),number($green),number($blue));

  @return $rgb;
}

$primary: "255,255,255" !default; // use rgb color without rgb. rgb(255,255) => 255,255
$anchor: scale-color(convertStringToColor($primary),$lightness: -14%) !default;
