Question

我有以下工作示例:

http://jsfiddle.net/Jaron787/tw3x9xt7/2/

我想让每个 TDclickable(在它周围的边框上突出显示)和按钮 1 或 2 的 onclick 以传递被单击的 TD 的 ID。

最好的方法是什么？ - 请更新工作示例

HTML

<div id="lse" class="display">
  <div id="centertbl">
    <table id="tblData" class="TSS">
      <tr>
        <td align="center" colspan="4"><b>Table 1</b></td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 1</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 2</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 3</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 4</td>
      </tr>
    </table>

    <table id="tblData" class="TSS">
      <tr>
        <td align="center" colspan="4"><b>Table 2</b></td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 1</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 2</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 3</td>
      </tr>
      <tr>
        <td align="center" colspan="4">Data 4</td>
      </tr>
    </table>
  </div>

  <input type="submit" class="button button1" name="submitButton" value="Button 1">
  <input type="submit" class="button button1" name="submitButton" value="Button 2">
</div>

CSS

.TSS {

  text-align: center;
  text-decoration: none;
  display: block;
  font-size: 16px;
  margin: 4px 2px;
  -webkit-transition-duration: 0.4s;

  transition-duration: 0.4s;
  cursor: pointer;
}

.button1 {

Answer 1

给每个td id:

<table id="tblData" class="TSS">
  <thead>
    <tr>
      <td align="center" colspan="4" id="td1"><b>Table 1</b></td>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td align="center" colspan="4" id="td2">Data 1</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td3">Data 2</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td4">Data 3</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td5">Data 4</td>
    </tr>
  </tbody>
</table>

<table id="tblData" class="TSS">
  <thead>
    <tr>
      <td align="center" colspan="4" id="td6"><b>Table 2</b></td>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td align="center" colspan="4" id="td7">Data 1</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td8">Data 2</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td9">Data 3</td>
    </tr>
    <tr>
      <td align="center" colspan="4" id="td10">Data 4</td>
    </tr>
  </tbody>
</table>

还有 CSS 在你点击它们时突出显示 td:

.td-hover {
    background-color: #4CAF50;
}

假设您使用 jQuery，这里是 javascript:

//onlick of a td will highlight the td clicked, if it's already been   highlighted the onclick event will remove the highlight.
$("td").click(function() {   
    if ($(this).hasClass("td-hover")) {
        $(this).removeClass("td-hover");
    } else {
        $(this).addClass("td-hover");
    }
})

//click on the button 1 or 2 will capture all id of the td that is highlighted
$(".button").click(function() {
    $("td").each(function() {
        if ($(this).hasClass("td-hover")) {
        var id = $(this).attr("id");
        alert(id);  // replace your function here
        }
    })
})
