javascript - 根据用户选择禁用单选按钮

Question

我有 2 组单选按钮，每组有 4 个选项。这 4 个选项在两个类别中都是相同的。我不想允许在两个类别中进行相同的选择。

例如 - 如果选择第一个类别中的选项 1，则用户现在只能从第二个类别中的选项 2/3/4 中进行选择。

这个问题之前已经被问过，但似乎没有什么对我的情况有用。这是我的代码 -

$("input[type=radio]").click(function() {
  
  $("input[type=radio][value=" + $(this).val() + "]").attr("disabled", "disabled");
  $(this).removeAttr("disabled");
});

table {
  border-collapse: collapse;
}

td,
th {
  border: 1px solid #ccc;
  padding: 10px;
}

th:empty {
  border: 0;
}

<table>
  <tr>
    <th>Most Supportive</th>
    <th>Reddit comment</th>
    <th>Most Offensive</th>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1a" data-min-check="1" required value="a" data-col="1"></td>
    <td>Comment 1</td>
    <td><input type="radio" name="Least1" id="Least-1a" data-min-check="1" required value="a" data-col="1"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1b" data-min-check="1" required value="b" data-col="2"></td>
    <td>Comment 2</td>
    <td><input type="radio" name="Least1" id="Least-1b" data-min-check="1" required value="b" data-col="2"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1c" data-min-check="1" required value="c" data-col="3"></td>
    <td>Comment 3</td>
    <td><input type="radio" name="Least1" id="Least-1c" data-min-check="1" required value="c" data-col="3"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1d" data-min-check="1" required value="d" data-col="4"></td>
    <td>Comment 4</td>
    <td><input type="radio" name="Least1" id="Least-1d" data-min-check="1" required value="d" data-col="4"></td>
  </tr>
</table>

Answer 1

首先启用所有单选按钮，然后禁用您想要禁用的单选按钮:

$("input[type=radio]").click(function() {
  console.log("here")
  $("input[type=radio]").removeAttr("disabled");
  $("input[type=radio][value=" + $(this).val() + "]").attr("disabled", "disabled");
  $(this).removeAttr("disabled");
});

table {
  border-collapse: collapse;
}

td,
th {
  border: 1px solid #ccc;
  padding: 10px;
}

th:empty {
  border: 0;
}

  <tr>
    <th>Most Supportive</th>
    <th>Reddit comment</th>
    <th>Most Offensive</th>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1a" data-min-check="1" required value="a" data-col="1"></td>
    <td>Comment 1</td>
    <td><input type="radio" name="Least1" id="Least-1a" data-min-check="1" required value="a" data-col="1"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1b" data-min-check="1" required value="b" data-col="2"></td>
    <td>Comment 2</td>
    <td><input type="radio" name="Least1" id="Least-1b" data-min-check="1" required value="b" data-col="2"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1c" data-min-check="1" required value="c" data-col="3"></td>
    <td>Comment 3</td>
    <td><input type="radio" name="Least1" id="Least-1c" data-min-check="1" required value="c" data-col="3"></td>
  </tr>
  <tr>
    <td><input type="radio" name="Most1" id="Most-1d" data-min-check="1" required value="d" data-col="4"></td>
    <td>Comment 4</td>
    <td><input type="radio" name="Least1" id="Least-1d" data-min-check="1" required value="d" data-col="4"></td>
  </tr>
