Question

我在之前的项目中使用了select2.js(3.4.5)，现在我需要对其进行一些更改。现在无法升级select2版本。

我需要更改background color搜索框的select2，我尝试了但我无法查看我的fiddle或代码段。用户从background-color:red选择选项后，我想要select box。

我尝试使用jquery

将所有元素应用于CSS

$('.select2-choices').attr("style",'background-color:#EA4335 !important'); $('.select2-choices > *').attr("style",'background-color:#EA4335 !important');

你也可以在我的代码中看到。
