好的，我的问题非常简单。一个选项可以有2个名字吗？我需要使用名称来获得2组，然后是2个子组。
所以，说我有2个选项列表。 我列出的所有内容都是“X”，列表2中的所有内容都是“C”。但是，每个选项都是别的。
的List1
<option name="X"name1="Y">
<option name="X"name1="D">
<option name="X"name1="Y">
列表2
<option name="C"name1="Y">
<option name="C"name1="D">
<option name="C"name1="Y">
那么，这可能吗？需要第一个名称来计算所选选项的总和乘以输入框中的数字。 （例如，期权价值= 3，输入= 6，总计18）
需要第二个名字来增加百分比奖励。 （例如，总数= 20，输入150％，新总数为30）
当使用getelementsbyname时，第一个名称是计算机可以在一个列表和另一个列表之间分辨。

答案 0 :(得分：2)
没有。如果您这样做，您的HTML代码将无效。
根据W3C documentation of <option>，它不能具有name或name1属性。
<强> SOLUTION：
这是data-属性的一个很好的用例。像这样使用它：
<option data-name1="C" data-name2="Y" value="M">M</option>
您的下拉菜单中看起来有很多选项。我建议在这种情况下使用HTML5 datalist，因为它允许用户在选项中进行搜索。
修改
要获取所选选项的数据属性，请按照以下示例操作：
document.getElementById("selectElement").selectedIndex = -1; // so that no option is selected when the page is loaded
function getData(){
var e = document.getElementById("selectElement"); // get the <select> element
var data_name1 = e.options[e.selectedIndex].dataset.name1; // get the selected <option> and its name1 data attribute
document.getElementById("data1").innerHTML = data_name1;
var data_name2 = e.options[e.selectedIndex].dataset.name2; // get the selected <option> and its name2 data attribute
document.getElementById("data2").innerHTML = data_name2;
var value = e.options[e.selectedIndex].value; // get the value of the selected <option>
document.getElementById("value").innerHTML = value;
}<select id="selectElement" onchange="getData()">
<option data-name1="1" data-name2="X" value="A">A</option>
<option data-name1="2" data-name2="Y" value="B">B</option>
<option data-name1="3" data-name2="Z" value="C">C</option>
</select>
<p>
<label>data-name1 = </label>
<span>"</span><span id="data1"></span><span>"</span>
</p>
<p>
<label>data-name2 = </label>
<span>"</span><span id="data2"></span><span>"</span>
</p>
<p>
<label>value = </label>
<span>"</span><span id="value"></span><span>"</span>
</p>
