Question

我有以下工作示例：

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

我想制作每个TDclickable（在它周围加上边框突出显示）和按钮1或2的onclick来传递被点击的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>

  </div>

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

Answer 1

为每个td提供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>

用CSS点击它们时突出显示td：

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

假设你使用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
        }
    })
})

Answer 2

查看这可能有助于jsfiddle

 $('td').on('click',function(){
    $(this).addClass('clicked');
  console.log('hi!');
});

   $('td').on('click',function(){
    $(this).addClass('clicked');
  console.log('hi!');
});

    $('.button.button1').on('click',function(){
         $( "td.clicked" ).each(function() {
          console.log($(this).attr('id'));
          var a = $(this).attr('id');
          $('.info').append(' Element id is: ' + a);
      });
    });

Answer 3

您是否只想拥有一个可选的TD或多个TD？您需要以任何一种方式使用JavaScript，这不能仅使用CSS和HTML来完成。

无论哪种方式，我都会使用jQuery并在td点击上添加'.selected'类，然后点击按钮，只需获取那些有'.selected'类的td ID。

$('td').on('click', function(){
    $('td').removeClass('selected');   //remove '.selected' class from all td elements
    $(this).addClass('selected');     //add '.selected' class on just the clicked one
});

$('.button').on('click', function(){
    var selectedId = $('td.selected').attr('id');    //fetch id of the id that has '.selected' class
    alert(selectedId);
});
