必需的标记不能以HTML格式运行

标签： html required

我想要实现的目标：

  1. HTML表格订购商品。
  2. QTY字段仅在选择相应项目时显示。
  3. 使其成为必需品。

    4. 我遇到了什么问题：

    1. 我正在尝试 NAME 所需的标记，但是当我提交表单而不填写名称时，表单允许我提交并且不会提示我填写名称字段。
    2. 没有提出“我想要实现的目标：2 ”
      3. 的代码

我已将输入类型按钮更改为提交，它应位于表单元素内。这是更新的代码。

要在选择更改时启用数量，这些是我在您的1个选择框中所做的更改，您可以为其他人复制相同的内容

<select name="SHIRT1" id="SHIRT1" onchange="enableQuantity(this.value, 'QTY1')">
        <option value=""></option>
        <option value="XS">XS</option>
        <option value="S">S</option>
        <option value="M">M</option>
    </select><br />
    <br>
    QTY
    <SELECT name="QTY1" id="QTY1" disabled>
        <option value=""></option>
        <option value="1">1</option>
        <option value="2">2</option>
        <option value="3">3</option>
    </SELECT>

和javascript 

function enableQuantity(selectValue, qtyEle) {
  document.getElementById(qtyEle).disabled = selectValue ? false : true;
}

希望这有效
