HTML表可以用ROW而不是COLUMN用JavaScript排序吗?

标签: javascript html5 html-table

我正在使用W3Schools的this code通过点击列标题对所有表行进行排序。正如预期的那样,它按照该col值对所有行进行排序。

我很害羞这已经得到了回答,但是我很难过滤serarch结果,找到一种类似的方法(希望在纯javascript中)通过点击第一列的行来排序列。

这应按所点击的行值排序所有列。

我希望某些组合方法可以按排序,具体取决于用户点击,但只需按行排序方法就可以了。

先谢谢!

预期行为

未排序的表格:

<table id="myTable">
  <tbody>
    <tr>
      <th onclick="sortTableRows(0)">Name</th>
      <th onclick="sortTableRows(1)">Col 1</th>
      <th onclick="sortTableRows(2)">Col 2</th>
      <th onclick="sortTableRows(3)">Col 3</th>
    </tr>
    <tr>
      <td onclick="sortTableCols(1)">Alan Brado</td>
      <td>2</td>
      <td>3</td>
      <td>1</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(2)">Kevin Chuca</td>
      <td>1</td>
      <td>3</td>
      <td>2</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(3)">Pamela Chu</td>
      <td>3</td>
      <td>2</td>
      <td>1</td>
    </tr> 
  </tbody>
</table>

正常:按COLUMN(第1列)对表格​​进行排序:

<table id="myTable">
  <tbody>
    <tr>
      <th onclick="sortTableRows(0)">Name</th>
      <th onclick="sortTableRows(1)">*Col 1*</th>
      <th onclick="sortTableRows(2)">Col 2</th>
      <th onclick="sortTableRows(3)">Col 3</th>
    </tr>
    <tr>
      <td onclick="sortTableCols(1)">Kevin Chuca</td>
      <td>1</td>
      <td>3</td>
      <td>2</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(1)">Alan Brado</td>
      <td>2</td>
      <td>3</td>
      <td>1</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(3)">Pamela Chu</td>
      <td>3</td>
      <td>2</td>
      <td>1</td>
    </tr> 
  </tbody>
</table>

渴望:ROW排序表(Alan Brado):

<table id="myTable">
  <tbody>
    <tr>
      <th onclick="sortTableRows(0)">Name</th>
      <th onclick="sortTableRows(1)">Col 3</th>
      <th onclick="sortTableRows(2)">Col 1</th>
      <th onclick="sortTableRows(3)">Col 2</th>
    </tr>
    <tr>
      <td onclick="sortTableCols(1)">*Alan Brado*</td>
      <td>1</td>
      <td>2</td>
      <td>3</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(2)">Kevin Chuca</td>
      <td>2</td>
      <td>1</td>
      <td>3</td>
    </tr>
    <tr>
      <td onclick="sortTableCols(3)">Pamela Chu</td>
      <td>1</td>
      <td>3</td>
      <td>2</td>
    </tr> 
  </tbody>
</table>

这是我的片段:

function sortTableRows(n) {
  var table, rows, switching, i, x, y, shouldSwitch, dir, switchcount = 0;
  table = document.getElementById("myTable");
  switching = true;
  dir = "asc"; 
  while (switching) {
    switching = false;
    rows = table.getElementsByTagName("TR");
    for (i = 1; i < (rows.length - 1); i++) {
      shouldSwitch = false;
      x = rows[i].getElementsByTagName("TD")[n];
      y = rows[i + 1].getElementsByTagName("TD")[n];
      if (dir == "asc") {
        if (x.innerHTML.toLowerCase() > y.innerHTML.toLowerCase()) {
          shouldSwitch= true;
          break;
        }
      } else if (dir == "desc") {
        if (x.innerHTML.toLowerCase() < y.innerHTML.toLowerCase()) {
          shouldSwitch= true;
          break;
        }
      }
    }
    if (shouldSwitch) {
      rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
      switching = true;
      switchcount ++;      
    } else {
      if (switchcount == 0 && dir == "asc") {
        dir = "desc";
        switching = true;
      }
    }
  }
}
function sortTableCols(n) {
  alert("This should sort cols by row #"+n+" values");

2 个答案:

答案 0 :(得分:1)

更新:请参阅@ sanxofon的回答。是我的改进。

暂时没有答案所以我最终使用此程序解决了问题:

  1. 将表格捕获到矩阵

  2. 转置矩阵(翻转轴)

  3. 按列排序(正常情况下)

  4. 向后移调矩阵(再次翻转轴)

  5. 将矩阵更新为表格

  6. 我发布此帖给任何可能对解决方案感兴趣的人。

    性能我还没有对其性能进行测试,但由于所有过程都是在矩阵上完成的,因此完全取决于它的长度和数据。效果很好,可以在任何桌子上实现。

    ToDo:可以通过添加行标题和列标题的侦听器以及从表中删除onClick="sortTable(x,y)"来改进。

    就是这样:

答案 1 :(得分:1)

我经常问自己这个问题,但似乎从来没有真正需要它,所以再也没有了。您的答案很棒,但在将数字作为字符串进行比较时,您会遇到问题。它不会显示在您的代码中,因为您使用的是1, 2, 3值。 使用混合数据类型检查我的代码段,当然代码可以减少很多。
