html - 更改选择标签下特定选项的颜色

问题描述

我正在使用 select 2 https://select2.org/，我想知道如何使用value="4". So when Mark as destroyedis selected it shows in a different colour. 我尝试直接设置类和内联 css，但两者都不起作用。

Not working: <option value="4" class="tx-orange">Mark as destroyed</option>

Not working: <option value="4" style="color:orange;">Mark as destroyed</option>

这就是选择块的样子

<select id="scanActionOptions" class="form-control select2">
   <option value="0">Verify</option>
   <option value="1">Mark as active</option>
   <option value="2">Mark as dispense</option>
   <option value="3">Mark as stolen</option>
   <option value="4">Mark as destroyed</option>
   <option value="5">Mark as sample</option>
   <option value="6">Mark as free sample</option>
   <option value="7">Mark as locked</option>
   <option value="8">Mark as exported</option>
   <option value="9">Mark as checkout</option>
   <option value="10">Mark as expired</option>
   <option value="11">Mark as recalled</option>
   <option value="12">Mark as withdrawn</option>
</select>

解决方案

$(document).ready(function() {
    $('.select2').select2();
});
/*selected css*/
.select2-container--default .select2-results__option--selected {
   color: orange;
   background:rgb(221 221 221 / 32%) !important;
}

/*hover css*/
.select2-container--default .select2-results__option--highlighted.select2-results__option--selectable {
    background-color: orange !important;
    color: white;
}

/*particular option color*/
.select2-container--default .select2-results>.select2-results__options li:nth-child(2) {
color: #fff;
background: red !important;
}

<select id="scanActionOptions" class="form-control select2">
   <option value="0">Verify</option>
   <option value="1">Mark as active</option>
   <option value="2">Mark as dispense</option>
   <option value="3">Mark as stolen</option>
   <option value="4">Mark as destroyed</option>
   <option value="5">Mark as sample</option>
   <option value="6">Mark as free sample</option>
   <option value="7">Mark as locked</option>
   <option value="8">Mark as exported</option>
   <option value="9">Mark as checkout</option>
   <option value="10">Mark as expired</option>
   <option value="11">Mark as recalled</option>
   <option value="12">Mark as withdrawn</option>
</select>

如果您需要更改选定的颜色，请在“.select2-container--default .select2-results__option--selected”上应用 css 并更改悬停 css，然后在“.select2-container--default .select2-results__option--highlighted.select2”上应用-results__option--可选”。如果您需要像第二个选项这样的颜色特定选项，那么您可以使用 ".select2-container--default .select2-results>.select2-results__options li:nth-child(2)" 。
