jQuery旧版本和较新版本中的select值（禁用的选项）中的差异

Question

I have updated jquery version from 1.7.2 to 2.1.1 in my project and used jquery migrate for fallback.

I found an issue related to value of select in jQuery 2.1.1 and 1.7.2.

1.7.2 --> "" (Blank)

2.1.1 --> null

Codepen

console.log("Version>>> 1.7.2 >>>> " + $jq("select").val());
console.log("Version>>> 2.1.1  >>> " + $("select").val());

Has anyone come around the similar issue and its workaround?

PS : I am using Native JS for the time being to make it work.

使用:selected jquery选择器，您将得到什么？

$("select option:selected")
