我想用基于枚举的函数加入导航选项卡。我在这里找到了后者的一个很好的例子：https://www.aspsnippets.com/Articles/Using-Switch-Case-with-Enum-in-JavaScript.aspx
但我得到的是：children() is not a function或siblings() is empty，这取决于我把函数调用和html标记放在哪里。
代码：
$(function(){
navTabActivate('one');
});
function navTabActivate(tab){
$('.nav-tabs a[id="' + tab + '"]').tab('show');
};
const TheNumber = {
"One": 1,
"Two": 2,
"Three": 3
};
var currentNumber = TheNumber.One
function number_switch(no) {
switch (parseInt(no)) {
case TheNumber.One:
console.log("And a one")
break;
case TheNumber.Two:
console.log("And a two")
break;
case TheNumber.Three:
console.log("And a three!")
break;
default:
currentNumber = TheNumber.One;
};

<a class="nav-link" id="two" data-toggle="tab" number="2">2</a>
</li>
<li class="nav-item" onclick="number_switch(this)">
<a class="nav-link" id="three" data-toggle="tab" number="3">3</a>
</li>
</ul>
和JS：
switch (parseInt(no.outerText)) {
}
