禁用基于值的选择选项*仅通过 HTML！* [英] Disable select options based on value *through the HTML only!*

问题描述

我需要根据变量的值禁用选择选项.该值类似于选择选项值之一，需要禁用.

I need to disable a select option based on the value of a variable. The value is similar to one of the select option value and it needs to be disabled.

例如，

<select>
<option>Value a</option>
<option>Value b</option>
</select>

$variable = <some select option value>;

因此，如果变量等于 Value a，则需要在选择选项中禁用它.

So if variable is equal to Value a then it needs to be disabled in select option.

谢谢.

推荐答案

使用您当前的标记，这将起作用:

With your current markup this will work:

$("select option:contains('Value b')").attr("disabled","disabled");
