Sass中的字符串替换

Sass 3.2.1

如何在字符串中替换文本的某些部分？例如，从颜色#fefefe中删除一个破折号#，使其成为fefefe

谢谢

简单的临时解决方案（以我的Mac为例）：

这是我刚刚使用的一个函数

SCSS-FUNCTION

/// Replace `$search` with `$replace` in `$string`
/// @author Hugo Giraudel
/// @param {String} $string - Initial string
/// @param {String} $search - Substring to replace
/// @param {String} $replace ('') - New value
/// @return {String} - Updated string
@function str-replace($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)), $search, $replace);
  }

  @return $string;
}

SCSS-用法：

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

@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)), $search, $replace)
  @return $string

$color-blue-night: #172b47    
$icon-normal: str-replace('' + $color-blue-night, '#', '')

.test {
  color: "172b47"; }

SCSS-RESULT:

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

@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)), $search, $replace)
  @return $string

$color-blue-night: #172b47    
$icon-normal: str-replace('' + $color-blue-night, '#', '')

.test {
  color: "172b47"; }

我使用缩进样式的SASS，因此这是我的转换，以获得一个颜色变量，在背景中替换为数据：href内联编码的css svg图像。#需要url编码，我使用全局颜色，只需在一个地方替换，即可工作

SASS-FUNCTION:

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

@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)), $search, $replace)
  @return $string

$color-blue-night: #172b47    
$icon-normal: str-replace('' + $color-blue-night, '#', '')

.test {
  color: "172b47"; }

SASS-USAGE:

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

@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)), $search, $replace)
  @return $string

$color-blue-night: #172b47    
$icon-normal: str-replace('' + $color-blue-night, '#', '')

.test {
  color: "172b47"; }

或者举个明确的例子

   .test
     color: str-replace('' + $color-blue-night, '#', '')

SASS-RESULT:

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

@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)), $search, $replace)
  @return $string

$color-blue-night: #172b47    
$icon-normal: str-replace('' + $color-blue-night, '#', '')

.test {
  color: "172b47"; }

字符串操作目前不是核心语言的一部分，但它看起来可能会在将来添加：请参阅此处的“添加自定义函数”一节：这里有一些更简洁的解决方案，用于在不使用

的情况下获取颜色值：

scss.test{color:str replace（#{$color blue night}，'.'}
