推荐答案
不要执行该函数，只需将其绑定到addEventListener并在单击时执行即可.
Do not execute the function , just bind it to addEventListener and execute it when clicked.
更改此
document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage());
对此
document.getElementById("showLocalStorage").addEventListener("click", showLocalStorage);
