本文实例为大家分享了JavaScript实现HTML表格排序功能,供大家参考,具体内容如下

HTML代码:

<table cellpadding="0" id="table">
    <tr class="top">
      <td>click me</td>
      <td>click me</td>
      <td>click me</td>
      <td>click me</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_bac.usa">15.43</span>
      </td>
      <td class="red">700</td>
      <td>1.220</td>
      <td class="red">阿</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_c.usa">7.05</span>
      </td>
      <td class="red">4</td>
      <td>3,000</td>
      <td class="red">炳</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_jpm.usa">30.62</span>
      </td>
      <td class="red">30</td>
      <td>2,558,800</td>
      <td class="red">和</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_axp.usa">22.30</span>
      </td>
      <td class="red">5</td>
      <td>6</td>
      <td class="red">瞎</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_mrk.usa">26.31</span>
      </td>
      <td class="red">0.6</td>
      <td>5</td>
      <td class="red">-</td>
    </tr>
    <tr>
      <td>
        <span id="bfn_la_pg.usa">63.16</span>
      </td>
      <td class="red">7</td>
      <td>4</td>
      <td class="red">子</td>
    </tr>
  </table>

    this.down = classDown; 
    this.startRow = startRow; 
    this.selectClass = selectClass; 
    this.endRow = (endRow == 999? this.rows.length : endRow); 
    this.T2Arr = this._td2Array();//所有受影响的td的二维数组 
    this.setShow(); 
  }, 
  //设置标签切换
