var songlists = documentquerySelectorAllsong_list__txt;var songlistText = ;var songlistss = documentquerySelectorAllsong_list__desc;var songlistText1 = ;for var i = 0; i songlistslength && i songlis

再便利songlistText1。如果要一一对应，可以使用一个数组来保存每个歌单的名称和描述，如下所示：

var songlists = document.querySelectorAll('.song_list__txt'); var songlistss = document.querySelectorAll('.song_list__desc'); var songlistArr = [];

for (var i = 0; i < songlists.length && i < songlistss.length; i++) { var name = songlists[i].textContent; var desc = songlistss[i].textContent; songlistArr.push({name: name, desc: desc}); }

for (var i = 0; i < songlistArr.length; i++) { var name = songlistArr[i].name; var desc = songlistArr[i].desc; console.log(name + "\n" + desc); }

这样就可以一一对应输出每个歌单的名称和描述了
