JavaScript 代码示例：从 HTML 元素提取并合并文本内容

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.push(songlists[i].textContent); songlistText1.push(songlistss[i].textContent); }

for (var j = 0; j < songlistText.length; j++) { console.log(songlistText[j] + ' ' + songlistText1[j]); }

var allSongLists = ''; for (var j = 0; j < songlistText.length; j++) { allSongLists += songlistText[j] + ' ' + songlistText1[j] + '\n'; }

console.log(allSongLists);
