Question

我是jquery和javascript的新手，我正在尝试编写一个简单的应用程序，当我按下按钮时，将一行从一个表复制到另一个表，然后从中删除该行第一张桌子。我有一个可以正常工作的DeleteRow功能，但我无法通过我的＆＃34; DraftPlayer＆＃34; 功能来复制该行。我已经尝试了很多我在网络上找到的解决方案，但我无法正确理解语法。在我解决这个问题时，您只会看到表格中的第二行有DraftPlayer按钮。

以下是我认为至关重要的代码段：

<!doctype html>
<html>
<head>
<meta charset="utf-8">

//<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</head>

<body>
<div>&nbsp;</div>
<p>Welcome to Mike's Draft App! </p>
<table id="players">
<table border="1">
  <tr>
    <td width="36"> Rank </td>
    <td width="141"> Player Name </td>
    <td width="52">Position </td>
    <td width="38">Team </td>
    <td width="69"> Bye Week </td>
    <td width="52"><input type="button" value="Delete" onClick="DeleteRow(this)"></td>
  </tr>
  <tr>
    <td>1</td>
    <td>Antonio Brown</td>
    <td>WR</td>
    <td>PIT</td>
    <td>8</td>
    <td><input type="button" value="Delete" onClick="DeleteRow(this)"></td>
    <td width="103">&nbsp;</td>
  </tr>
  <tr>
    <td>2</td>
    <td>Julio Jones</td>
    <td>WR</td>
    <td>ATL</td>
    <td>11</td>
    <td><input type="button" value="Delete" onClick="DeleteRow(this)"></td>
    <td><input type="button" value="Draft" onClick="DraftPlayer(this)"></td>
  </tr>

<table id="drafted">
<table border="1">
  <tr>
    <td width="36"> Rank </td>
    <td width="141"> Player Name </td>
    <td width="52">Position </td>
    <td width="38">Team </td>
    <td width="69"> Bye Week </td>
  </tr>
  </table>


<script>
    function DeleteRow(o) {
     var p=o.parentNode.parentNode;
         p.parentNode.removeChild(p);
    }

    function DraftPlayer(o) {
     var p=o.parentNode.parentNode;

    copyTable = $('#drafted tbody');
    cloneRow = p.clone();
    copyTable.append(cloneRow);

    p.parentNode.removeChild(p);     

    }
</script>
</body>
</html>

感谢您的任何建议！

Answer 1

您正在选择DOM中不存在的$('#drafted tbody');，这样您就什么也得不到。您需要将tbody添加到表格中，或者需要更改选择器。

<table id="drafted">
 <tbody>
   <tr>
    <th width="36"> Rank </th>
    <th width="141"> Player Name </th>
    <th width="52">Position </th>
    <th width="38">Team </th>
    <th width="69"> Bye Week </th>
   </tr>
  </tbody>
</table>

function DraftPlayer(o) {
        var p = $(o).closest('tr');
        copyTable = $('#drafted tbody');
        cloneRow = p.clone();
        copyTable.append(cloneRow)
        p.remove();

    }

    function DeleteRow(o) {
     var p=o.parentNode.parentNode;
         p.parentNode.removeChild(p);
    }

    function DraftPlayer(o) {
     var p=o.parentNode.parentNode;

    copyTable = $('#drafted tbody');
    cloneRow = p.innerHTML;

//alert(cloneRow )
    copyTable.append("<tr>"+cloneRow+"</tr>");

    p.parentNode.removeChild(p);     

    }

您的代码中存在很多错误。浏览我的代码，编辑它，工作正常

Answer 3

您需要将DOM元素转换为jquery对象才能使用clone（）函数。修改后的DraftPlayer（）函数是：

function DraftPlayer(o) {
 var p=o.parentNode.parentNode;

copyTable = $('#drafted tbody');
cloneRow = $(p).clone();
copyTable.append(cloneRow);

p.parentNode.removeChild(p);     

}

<强>建议：
你的HTML也存在一些问题修改表格标签。

<table id="your_id" border="1">
       <tbody>
         -----------
         -----------
      </tbody>
</table>
