how to disable the entire dropdown control in html
提问by leora
i see there is a disabled property on a specific item in the dropdown list but is there an enabled property on the whole html dropdown itself?
我看到下拉列表中的特定项目有一个禁用的属性，但是整个 html 下拉列表本身是否有一个启用的属性？
any suggestions?
有什么建议？

According to the HTML 4 speca selectelement has a disabledattribute.
根据HTML 4 规范，select元素具有disabled属性。
So
所以
<select disabled>
<option>Something</option>
</select>
should work
应该管用

disabled="disabled"
This will disable a value within the combo box (it will still show up, but it will not have the ability to be selected):
这将禁用组合框中的一个值（它仍然会显示，但不能被选中）：
<select>
<option disabled="disabled" value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
This will disable the whole combo box:
这将禁用整个组合框：
<select disabled="disabled">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
