The idea is for default popup to work as a settings page it goes without saying that it should show the current set values and you should be able to change them. 这个想法是让默认弹出窗口作为设置页面起作用，不用说它应该显示当前设置值，并且您应该能够更改它们。 Bare in mind I am new to this and this is just a jumble of code from variaty of projects any pointers would be appreciated. 简而言之，我对此并不陌生，这只是各种项目中混杂的代码，任何指针都将不胜感激。

The question is why is it not working, it doesnt save values and neither does it show default values when you open the pop up 问题是为什么它不起作用，它不保存值，并且当您打开弹出窗口时也不显示默认值

You have to store like 你必须像

localStorage.setItem("lastname", "Arun");
localStorage.getItem("lastname");
