嵌入HTML的Javascript和CSS无法正常工作

Question

我在这里有点新，所以如果我做错任何事，请纠正我。

基本上，我尝试创建一个“任务表”，在其中，除了能够按照他们的同意编辑任务之外，用户还可以添加更多任务。 我已经编写了一些表格（并感谢Ash Blue提供了基本模板），但是遇到了一些问题。

首先，如果将鼠标悬停在“停止”或“暂停”按钮上，您将看到它们左侧的按钮也将起作用。 接下来，“添加任务”和“导出任务”按钮不起作用。 这是他们应该工作的： CodePen。 最后，我还没有对此进行编码，但是额外行上的“开始/时间”时间框需要具有不同的变量，否则，当单击一行上的开始按钮时，所有行的所有秒表都会启动。 抱歉，这还不太清楚，但是如果您听不清楚，我将尝试更详细地说明。

这是当前代码：

var $TABLE = $('#table');
var $BTN = $('#export-btn');
var $EXPORT = $('#export');

$('.table-add').click(function() {
  var $clone = $TABLE.find('tr.hide').clone(true).removeClass('hide table-line');

  $row.prev().before($row.get(0));
});

$('.table-down').click(function() {
  var $row = $(this).parents('tr');
  $row.next().after($row.get(0));

// A few jQuery helpers for exporting only
jQuery.fn.pop = [].pop;
jQuery.fn.shift = [].shift;

$BTN.click(function() {
  var $rows = $TABLE.find('tr:not(:hidden)');
  var headers = [];
  var data = [];

  // Get the headers (add special header logic here)
  $($rows.shift()).find('th:not(:empty)').each(function() {
    headers.push($(this).text().toLowerCase());
  });

  // Turn all existing rows into a loopable array
  $rows.each(function() {
    var $td = $(this).find('td');
    var h = {};

    // Use the headers from earlier to name our hash keys
    headers.forEach(function(header, i) {
      h[header] = $td.eq(i).text();
    });

    data.push(h);
  });

  // Output the result
  $EXPORT.text(JSON.stringify(data));
});

如果以后在同一张桌子上确实遇到任何问题，我是否还要发表另一个问题？ 还是我应该编辑这篇文章？

Answer 1

您只需要关闭span标签：

<span class="glyphicon glyphicon-play play"></span>
<span class="glyphicon glyphicon-pause pause"></span>
<span class="glyphicon glyphicon-stop stop"></span>

Answer 2

我认为其他两个按钮都工作正常。 可能是您隐藏的tr应该是这个样子？

<tr class="hide">
    <td contenteditable="true"></td>
    <td contenteditable="true"></td>
    <td contenteditable="true"></td>
    <td contenteditable="true"></td>
    <td contenteditable="true"></td>
    <td>
      <span class="glyphicon glyphicon-play play"></span>
      <span class="glyphicon glyphicon-pause pause"></span>
      <span class="glyphicon glyphicon-stop stop"></span>
    </td>
    <td>
      <span class="table-up glyphicon glyphicon-arrow-up"></span>
      <span class="table-down glyphicon glyphicon-arrow-down"></span>
      <span class="table-remove glyphicon glyphicon-remove"></span>
    </td>
    <td>
    </td>
</tr>
