function clickAiSendDescription() { $('#id-listing-settings').on('click', '.sell-description-click-for-ai', function (e) { let head_box_div = $('#id-listing-settings').find('#textarea-edit'); let domain_id = $(this).data('domain-id'); let data = {}; let url = window.location.pathname; data.send_ai = 'send_ai'; data.domain_id = domain_id; data.question_id = 1; data.question_style_id = -1; $.ajax({ url: url, type: 'POST', data: data }).done(function (responseData) { let json = JSON.parse(responseData); if (json.code === '0') { let text = $(json.message).text(); head_box_div = head_box_div.scrollTop(head_box_div[0].scrollHeight); printTextVerbatim(head_box_div.children(), text); } }) e.stopPropagation(); }) }. 这段代码可以实现文本域随着文本滚动到最下面吗

这段代码有一点小问题，您可以将这一行：

head_box_div = head_box_div.scrollTop(head_box_div[0].scrollHeight);

改为：

head_box_div.scrollTop(head_box_div[0].scrollHeight);

即可实现文本域随着文本自动滚到最下面。完整的修改后的代码如下所示：

function clickAiSendDescription() {
  $('#id-listing-settings').on('click', '.sell-description-click-for-ai', function (e) {
    let head_box_div = $('#id-listing-settings').find('#textarea-edit');
    let domain_id = $(this).data('domain-id');
    let data = {};
    let url = window.location.pathname;
    data.send_ai = 'send_ai';
    data.domain_id = domain_id;
    data.question_id = 1;
    data.question_style_id = -1;
    $.ajax({
      url: url,
      type: 'POST',
      data: data
    }).done(function (responseData) {
      let json = JSON.parse(responseData);
      if (json.code === '0') {
        let text = $(json.message).text();
        head_box_div.scrollTop(head_box_div[0].scrollHeight);
        printTextVerbatim(head_box_div.children(), text);
      }
    })
    e.stopPropagation();
  })
}

希望能对您有所帮助。
