这是我单击“更新”按钮时的代码

var updateRowData = [];

$('button').click((e) => {
  var btnClassClicked = e.target.className;

  if (btnClassClicked.includes('btn-warning')) {
    $('#existingTrunkTable').on('click', 'tbody tr', function() {
      updateRowData.push({
        "trunkNo": $(this).find($("td[name=trunkNo]")).text(),
        "username": $(this).find($("td[name=username]")).text(),
        "password": $(this).find($("td[name=password]")).text(),
        "registrar": $(this).find($("td[name=registrar]")).text(),
        "voiceChannels": $(this).find($("td[name=voiceChannels]")).text(),
        "type": $(this).find($("td[name=type]")).text(),
        "group": $(this).find($("td[name=group]")).text()
      });
    });

    console.log('updateRowData', updateRowData)
    console.log('updateRowData[0]', updateRowData[0].trunkNo)

    $('#selectedTrunkNo').text(updateRowData[0].trunkNo);
    $('#password').val(updateRowData[0].password);
    $('#edit_voiceChan').val(updateRowData[0].voiceChannels);

        </button>
      </td>

  </tbody>
</table>

这就是我得到的:

以上数据均为测试数据。
它也不喜欢 eq .我需要做的是获取 'trunkNo' 值并预弹出相关 input表格显示时。
为了

console.log('1', updateRowData[0].length)

我得到

Answer 1

几件事

箭头函数中没有 $(this)

使用 .closest 获取您所在的行

事件处理程序的包装过多

当你有 hasClass

时不要测试 className

使用数据属性代替 name

var updateRowData = [];

$('button').on("click", function() {
  if ($(this).hasClass('btn-warning')) {
    const $row = $(this).closest("tr")
    updateRowData.push({
      "trunkNo": $row.find($("[data-name=trunkNo]")).text(),
      "username": $row.find($("[data-name=username]")).text(),
      "password": $row.find($("[data-name=password]")).text(),
      "registrar": $row.find($("[data-name=registrar]")).text(),
      "voiceChannels": $row.find($("[data-name=voiceChannels]")).text(),
      "type": $row.find($("[data-name=type]")).text(),
      "group": $row.find($("[data-name=group]")).text()
    });
console.log(updateRowData)
    $('#selectedTrunkNo').text(updateRowData[0].trunkNo);
    $('#password').val(updateRowData[0].password);
    $('#edit_voiceChan').val(updateRowData[0].voiceChannels);
    $('#edit_typeDd').val(updateRowData[0].type);
    $('#edit_existingGroupTrunks').val(updateRowData[0].group);
  }
})
