我有一个SASS / SCSS字符串,其中包含两个列表(以逗号分隔),每个列表包含数字(由空格分隔).如何将字符串拆分为两个数字列表? SCSS: $values: "10px 20px 30px, 20px 30px 40px";$begin: /* should be */
          SCSS:
$values: "10px 20px 30px, 20px 30px 40px"; $begin: /* should be */ "10px", "20px", "30px"; $end: /* should be */ "20px", "30px", "40px"; // optionally it can be a map: $begin: (10px, 20px, 30px); $end: (20px, 30px, 40px);

STR-分裂
@function str-split($string, $separator) {
    // empty array/list
    $split-arr: ();
    // first index of separator in string
    $index : str-index($string, $separator);
    // loop through string
    @while $index != null {
        // get the substring from the first character to the separator
        $item: str-slice($string, 1, $index - 1);
        // push item to array
        $split-arr: append($split-arr, $item);
        // remove item and separator from string
        $string: str-slice($string, $index + 1);
        // find new index of separator
        $index : str-index($string, $separator);
    }
    // add the remaining string to list (the last item)
    $split-arr: append($split-arr, $string);
    @return $split-arr;
} 
 用法
在您的情况下,您可以这样使用它:
$values: "10px 20px 30px, 20px 30px 40px";
$list: ();
$split-values: str-split($values, ", ");
@each $value in $split-values {
  $list: append($list, str-split($value, " "));
} 
 转换为数字
至于将字符串值转换为数字,请查看Hugo Giraudel在SassMeister上的功能(或阅读他的blog post)
