Question

我确实看到了SO的另一种解决方案，但是它使整个文件没有新行。我只需要一个没有新行的特定部分。

我正在尝试删除这些标签之间的间距，以使它们彼此紧挨着，例如：

<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a>

它们当前如下所示：

                          <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>

Answer 1

这是我在注释中建议的正则表达式的示例，我添加了\t和\s{2,}来拉出制表符和2个或更多空格字符。

let temp = `<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>
                              <a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
                                <img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
                              </a>`;


console.log(temp.replace(/[\r\n|\r|\n|\t]/g, '').replace(/\s{2,}/g, ' '))

Answer 2

此模式应该有效：(?<=>)\s*|\s*(?=<a)

您可以看到一个演示here。只需将匹配项替换为""

如何使用正则表达式删除这些标签之间的换行符？
