当鼠标悬停在< select>中的项目上时,有没有办法更改光标？组合框？我假设做了选项{cursor：pointer;在CSS中可以工作,但似乎没有.
解决方法
可悲的是,< option>标记由操作系统而不是浏览器呈现,因此您无法使用游标设置它们的样式.相反,使用像
Bootstrap’s Dropdown这样的插件.
Except for background-color and color,style settings applied through the style object for the option element are ignored. In addition,style settings applied directly to individual options override those applied to the containing select element as a whole.
Some elements simply can’t be styled using CSS. These include all advanced user interface widgets such as range,color,or date controls as well as all the dropdown widgets,including
<select>,<option>,<optgroup>and<datalist>elements. The file picker widget is also known not to be stylable at all. The new<progress>and<meter>elements also fall in this category.
