我正在寻找为每个选项构建多个具有自定义背景颜色的 html 选择元素：

<select runat="server" id="select">
<option value="A">White</option>
<option value="B">Red</option>
<option value="C">Yellow</option>
<option value="D">Green</option>

当网站加载时，我希望选择元素只显示背景颜色而不显示所选选项的文本。文本（白色、红色、....）应仅在打开下拉列表时可见。

随着用户更改所选值，背景颜色也应更改，而文本应在关闭的下拉列表中不可见。

如果该解决方案适用于包括 IE 9/10 在内的大多数浏览器，那就太好了。

干杯。

试试这个代码，适用于包括 IE 在内的所有浏览器：

html

<select id="select1" onchange="colourFunction()">
<option class="white" value="A">This should have a WHITE background</option>
<option class="red" value="B">This should have a RED background</option>
<option class="yellow" value="C">This should have a YELLOW background</option>
<option class="green" value="D">This should have a GREEN background</option>
</select>

css

#select1 {width:150px; color:rgba(0, 0, 0, 0);}
#select1:focus, #select1:focus {
color:black;
}
.white {background:white;}
.red {background:red;}
.yellow {background:yellow;}
.green {background:green}

js

function colourFunction() {
var myselect = document.getElementById("select1"),
colour = myselect.options[myselect.selectedIndex].className;
myselect.className = colour;
myselect.blur(); //This just unselects the select list without having to click
somewhere else on the page
}

HTH :)

这与@Singh 几乎相同，只是做了一些小改动以使其更加灵活，它允许您进行多个选择更改颜色。

CSS

<style>
    .red {
        color: darkred;
        background-color: red;
    }

    .purple {
        color: darkmagenta;
        background-color: magenta;
    }

    .yellow {
        color: darkkhaki;
        background-color: yellow;
    }

    .aqua {
        color: mediumaquamarine;
        background-color: aqua;
    }

    .blue {
        color: lightblue;
        background-color: blue;
    }

    .green {
        color: lightgreen;
        background-color: green;
    }
</style>

html

<select name="pos1" id="pos1" onchange="colourFunction(this)">
    <option disabled selected value>select</option>
    <option class="red" value="1">Red</option>
    <option class="purple" value="2">Purple</option>
    <option class="yellow" value="3">Yellow</option>
    <option class="aqua" value="4">Aqua</option>
    <option class="blue" value="5">Blue</option>
    <option class="green" value="6">Green</option>
</select>

<select name="pos2" id="pos2" onchange="colourFunction(this)">
    <option disabled selected value>select</option>
    <option class="red" value="1">Red</option>
    <option class="purple" value="2">Purple</option>
    <option class="yellow" value="3">Yellow</option>
    <option class="aqua" value="4">Aqua</option>
    <option class="blue" value="5">Blue</option>
    <option class="green" value="6">Green</option>
</select>

JS

<script>
    function colourFunction(pos) {
        pos.className = pos[pos.selectedIndex].className;
        pos.blur();
    }
</script>
