Question

我有3套复选框 - checkboxDofM，checkboxMonth和checkboxDay。我想检查是否检查了checkboxDofM的任何一个方框。如果是，则用户不应该检查checkboxDay的任何框。同样，如果选中checkboxDay中的任何框，则用户应该无法选择checkboxDofM的任何框。唯一的问题是我不知道如何执行此操作，因为我无法控制正在生成的复选框的ID和名称，"checked"功能似乎无法正常工作。有人可以帮我这个吗？

我的意思是检查不工作是这样的：

    <script>
let checkboxDofMElements = document.getQuerySelectorAll('.checkboxDofM');

for(let i = 0; i < checkboxDofMElements.length; i++)
{
 checkboxDofMElements[i].addEventListener('change', function(event)
 {
   if(this.checked)
   {
     console.log("Something has changed");
   }
   else
   {
     console.log("nothing has changed");
   }
 });
}
</script>

当我添加上面的脚本时，它应该返回＆＃34;某些内容已经改变＆＃34;。相反，它返回＆＃34;没有任何改变＆＃34;消息。

Answer 1

而不是document.getQuerySelectorAll('.checkboxDofM')，您最常使用Element.querySelectorAll()

而不是使用this.checked，您可以使用event.target.checked

代码示例：

const checkboxDofMElements = document.querySelectorAll('.checkboxDofM');

checkboxDofMElements.forEach(el => el.addEventListener('change', event => {
  const str = event.target.checked ? 'Something has changed' : 'nothing has changed';
  console.log(`${str} for day ${event.target.value}`);
}));

<input type="checkbox" name="day" value="1" class="checkboxDofM"> 1<br>
<input type="checkbox" name="day" value="2" class="checkboxDofM"> 2<br>
