玉recursif变量没有复位

Question

我有一些路径：

CCCCC,D D D D,aaaaa,bbbbb,test 2.txt,test1.txt,CCCCC/a,CCCCC/a/test 2.txt,CCCCC/a/test1.txt,D D D D/aaaa.fr,D D D D/test 2.txt,D D D D/test1.txt,D D D D/aaaa.fr/test 2.txt,D D D D/aaaa.fr/test1.txt,aaaaa/test 2.txt,aaaaa/test1.txt,bbbbb/aaaaaaaaaaa.txt,bbbbb/fffffffff,bbbbb/fffffffff/test 2.txt,bbbbb/fffffffff/test1.txt 

我创建树（file.id和file.children）递归和我一起JADE显示...

我试着写正确路径但不起作用。

玉（开始与空字符串的路径：

mixin file_list(files, path) 
ul 
    each file, i in files 
     li 
      - if(file.children.length > 0){ 
      span #{file.id} 
      - path += file.id + '\\'; 
      mixin file_list(file.children, path) 
      - }else{ 
      span 
       a(href='#{path}#{file.id}') #{file.id} 
      - } 

显示：

<ul> 
     <li><span>CCCCC</span> 
      <ul> 
       <li><span>a</span> 
        <ul> 
         <li><span><a href="CCCCC\a\test 2.txt">test 2.txt</a></span></li> 
         <li><span><a href="CCCCC\a\test1.txt">test1.txt</a></span></li> 
        </ul> 
       </li> 
      </ul> 
     </li> 
     <li><span>D D D D</span> 
      <ul> 
       <li><span><a href="CCCCC\D D D D\test 2.txt">test 2.txt</a></span></li> 
       <li><span><a href="CCCCC\D D D D\test1.txt">test1.txt</a></span></li> 
       <li><span>aaaa.fr</span> 
        <ul> 
         <li><span><a href="CCCCC\D D D D\aaaa.fr\test 2.txt">test 2.txt</a></span></li> 
         <li><span><a href="CCCCC\D D D D\aaaa.fr\test1.txt">test1.txt</a></span></li> 
        </ul> 
       </li> 
      </ul> 
     </li> 
     <li><span>aaaaa</span> 
      <ul> 
       <li><span><a href="CCCCC\D D D D\aaaaa\test 2.txt">test 2.txt</a></span></li> 
       <li><span><a href="CCCCC\D D D D\aaaaa\test1.txt">test1.txt</a></span></li> 
      </ul> 
     </li> 
     <li><span>bbbbb</span> 
      <ul> 
       <li><span><a href="CCCCC\D D D D\aaaaa\bbbbb\aaaaaaaaaaa.txt">aaaaaaaaaaa.txt</a></span></li> 
       <li><span>fffffffff</span> 
        <ul> 
         <li><span><a href="CCCCC\D D D D\aaaaa\bbbbb\fffffffff\test 2.txt">test 2.txt</a></span> 
         </li> 
         <li><span><a href="CCCCC\D D D D\aaaaa\bbbbb\fffffffff\test1.txt">test1.txt</a></span></li> 
        </ul> 
       </li> 
      </ul> 
     </li> 
    </ul> 

为什么变量路径不重置

试试这个，

mixin file_list(files, path) 
ul 
    each file, i in files 
     - var filePath = path; 
     li 
      - if(file.children.length > 0){ 
      span #{file.id} 
      - filePath += file.id + '\\'; 
      mixin file_list(file.children, filePath) 
      - }else{ 
      span 
       a(href='#{filePath}#{file.id}') #{file.id} 
      - }
