var songlists = documentquerySelectorAllsong_list__txt;var songlistText = ;songlistsforEachfunctionsonglist songlistText += songlisttextContent + n;;var songlistss = documentquerySelectorAllsong_l

您可以使用for循环来实现每一次循环一一对应song_list__txt和song_list__desc，如下所示：

var songlists = document.querySelectorAll('.song_list__txt'); var songlistText = ""; var songlistss = document.querySelectorAll('.song_list__desc'); var songlistText1 = "";

for (var i = 0; i < songlists.length && i < songlistss.length; i++) { songlistText += songlists[i].textContent + "\n"; songlistText1 += songlistss[i].textContent + "\n"; }

console.log(songlistText + songlistText1);

这样，song_list__txt和song_list__desc就能够一一对应了
