对复选框html使用if-else条件

我对这件事也有同样的问题， 但是我的没有按钮。你知道我能做什么吗

这是我的代码：

<label for="exampleInputEmail1">Category*</label>
            <table>
              <tr>
                <td>
                  <div class="form-check form-check-inline">
                      <label class="form-check-label">
                          <input class="form-check-input" type="checkbox" id="meti_d" value="METI Member - Domestic"> METI Member - Domestic
                      </label>
                  </div>
                </td>
                <td>
                  <div class="form-check form-check-inline">
                      <label class="form-check-label">
                          <input class="form-check-input" type="checkbox" id="lec_d" value="Lecturer - Domestic"> Lecturer - Domestic
                      </label>
                  </div>
                </td>
              </tr>
              <tr>
                <td>
                  <div class="form-check form-check-inline">
                      <label class="form-check-label">

                  </div>
                </td
              </tr>
              <tr>
                <td>
                  <div class="form-check form-check-inline">

在输入标记中添加属性onchange=“category（）；”，如下所示

<input class="form-check-input" type="checkbox" id="meti_i" value="METI Member - International ">


您能告诉我们您尝试过什么，我们可以看看吗？您的代码目前是什么样子的？我已经编辑过了，谢谢提醒我
<div class="form-group">
    <label for="exampleInputEmail1">Price</label>
    <input type="text" class="form-control" id="price" aria-describedby="emailHelp" name="price">
</div>

<input class="form-check-input" type="checkbox" id="meti_i" value="METI Member - International ">
