我正在嘗試從Discogs.com html解析曲目名稱。以下是 html 部分的示例：<tr class=" tracklist_track track" data-track-position="8">        <td class="tracklist_track_pos">8</td>          <td class="track tracklist_track_title ">            <span class="tracklist_track_title">Shapeshifting</span><blockquote><span class="tracklist_extra_artist_span">Vocals – <a href="/artist/764815-Rachel-Dreyer">Rachel Dreyer</a></span></blockquote></td>        <td width="25" class="tracklist_track_duration">            <span>6:02</span>        </td>    </tr><tr class=" tracklist_track track" data-track-position="9">        <td class="tracklist_track_pos">9</td>        <td class="track tracklist_track_title ">            <span class="tracklist_track_title">Rose</span><blockquote><span class="tracklist_extra_artist_span">Vocals – <a href="/artist/764814-Silke-Roch">Silke Roch</a></span></blockquote></td>        <td width="25" class="tracklist_track_duration">            <span>5:49</span>        </td>    </tr>我的目標是提取innerText類tracklist_track_title( "Shapeshifting", "Rose")。如果我試試這個：document.getElementsByClassName("tracklist_track_title")，我收到陣列，其中包括類track tracklist_track_title，tracklist_track_title和tracklist_extra_artist_span。( "Shapeshifting", "Shapeshifting", "Vocals – Rachel Dreyer", "Rose", "Rose", "Vocals – Silke Roch")如果我嘗試這個：document.getElementsByClassName("track tracklist_track_title")，我只接受track tracklist_track_title課程，但不幸的tracklist_extra_artist_span是課程也包括在內(nèi)。( "Shapeshifting", "Vocals – Rachel Dreyer", "Rose", "Vocals – Silke Roch").你能不能給我建議一種只包含tracklist_track_title在結果數(shù)組中的方法，或者之后過濾這個數(shù)組以擺脫tracklist_extra_artist_span類？( "Shapeshifting", "Rose").我唯一的想法是使用document.getElementsByClassName("tracklist_track_title")然后過濾結果數(shù)組中具有偶數(shù)索引的所有元素以擺脫track tracklist_track_title類：var trackBlock = document.getElementsByClassName("tracklist_track_title");var trackList = [];for (var i = 0; i < trackBlock.length; i++) {    if(i % 2 != 0) { // index is not even        trackList.push(trackBlock[i].innerText);    }}還有其他想法嗎？謝謝！
