如何在SASS中将字符串分成两个数字列表？

问题描述：

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（以空格分隔）。我如何将字符串分成两个数字列表？

I have a SASS/SCSS string which contain two lists (separated by comma), and each list contain numbers (separated by space). How can i split string into two lists of numbers?

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);

好吧，您可以使用以下功能拆分字符串：

Well, you can split the string with this function:

@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;
}

在您的情况下，您可以这样使用：

In your case you could use it as so:

$values: "10px 20px 30px, 20px 30px 40px";
$list: ();

$split-values: str-split($values, ", ");
@each $value in $split-values {
  $list: append($list, str-split($value, " "));
}

要将字符串值转换为数字，请查看 SassMeister （或阅读他的博客文章）
