什么原因会使 html select 标签卡住？

Html5

慕尼黑5688855 2023-10-17 14:59:42

我用 HTML、CSS 和 JS 构建了一个二进制棋盘游戏，然后添加了一个选择标签，该标签将更改棋盘的级别，这意味着它将在表中添加/删除行和列问题是选择标签被卡住意味着它不会删除选项标签列表我不明白为什么它被卡住，所以我删除了1 个<label></label>标签2 <select id="levels" onchange="changeLevel()">id & onchange 属性3<option value="5" selected > Easy </option>取值及选择属性但它仍然卡住了我在谷歌上发现一些内容说我的CSS代码可能会影响它我检查了它并且它没有受到CSS代码的影响我无法预料为什么会发生这种情况，我之前确实多次使用了 select 标签，但我不明白为什么会发生这种情况
