Question

我想显示两个文本字符串，具体取决于用户从两个下拉列表中的选择。

所以有两个下拉选项： enter image description here

对于每个月选项，我想要一个相应的值。因此，对于1月选项，该值将为“1月名称”。对于每种颜色选项，还有相应的值。因此对于绿色选项，值为“绿色名称”。

一旦用户选择了两个选项（月份和颜色），我希望输出显示带有两个值串联的文本。

例如，如果我选择January和Green，输出将为：

enter image description here

如果我将月份更改为其他内容，则名称会相应更新。

我将一些html / css代码放在一起作为开始http://jsfiddle.net/baumdexterous/ys3GS/。如果有人能够阐明如何使用jquery完成这项任务，我将不胜感激！另外 - 如何使文本输出淡入？非常感谢你!!!

        <label class="Red" for="Red">Red Name</label>
    </form>

  <!--  <p class="output">YOUR ANIMAL NAME IS JANUARY NAME GREEN NAME</p> -->

</body>

顺便说一句 - 我也想设置选择字段的样式...所以将它们作为列表项（li，ul）更有意义吗？

Answer 1

$("#month, #color").change(function () {
    var month = $("#month").val();
    var color = $("#color").val();
    var content = '';
    if (month && color) {
        var monthlabel = $("label[for="+month+"]").text();
        var colorlabel = $("label[for="+color+"]").text();
        content = 'Your animal name is ' + monthlabel + ' ' + colorlabel;
    }
    $("#output").text(content).fadeIn();
});
