回答by jay c.
Alternatively, you can also pass the li element itself to your myfunction function as shown:
或者，您也可以将 li 元素本身传递给 myfunction 函数，如下所示：
function myfunction(ctrl) {
var TextInsideLi = ctrl.getElementsByTagName('p')[0].innerHTML;
}
and in your HTML, <li onclick="myfunction(this)">
在你的 HTML 中， <li onclick="myfunction(this)">

If you use eg. "id" you can do it this way:
如果你使用例如。“id”你可以这样做：
(function() {
let x = document.getElementById("idName");
let y = document.getElementById("liName");
y.addEventListener('click', function(e) {
y.appendChild(x);
});
})();<html lang="en">

Use jQuery:
使用jQuery：
$("li").find("p").html()
should work.
应该管用。
