var nodeLists = ["/data1/chenleileitest/1T/"]如何快速將上述數(shù)組變換成如下的格式["/data1/"，"/data1/chenleileitest/"，"/data1/chenleileitest/1T/"]我想的是使用split對(duì)數(shù)組元素劃分，然后再拼接，但這是對(duì)數(shù)組元素只有一個(gè)的情況比較好處理，如果數(shù)組的元素比較多的情況呢？["/data1/chenleileitest/1T/","/boot/gurb2/themes/system/","/sys/dev/block/8:16/device/"]將其轉(zhuǎn)換成如下形式["/data1/","/data1/chenleileitest/","/data1/chenleileitest/1T/","/boot/","/boot/gurb2/","/boot/gurb2/themes/","/boot/gurb2/themes/system/","/sys/","/sys/dev/","/sys/dev/block/","/sys/dev/block/8:16/","/sys/dev/block/8:16/device/",]var nodeList  = [];nodeList = nodeLists.map(function(value, index, array) {            return '/'+value          }).filter(function(item,index, array){            return item !== '/'          })得到的結(jié)果是：["/data1", "/chenleileitest", "/1T"]實(shí)現(xiàn)想要的結(jié)果需要，第一的加上第二個(gè)，第一個(gè)加第二個(gè)加第三個(gè)，組成最終想要的結(jié)果
