What is the best way to capture just the refresh event without intercepting the close event or any changes to the

Is there a way to detect the refresh button click (F5) in a specific scenario? I have a task that involves clearing my localStorage whenever the refresh button is clicked, but also ensuring that if the URL changes or the page is closed, the localStorage retains its data. I've come across various topics related to this issue, with the main suggestion being to use window.onbeforeunload. However, this event seems to trigger at any change, not just when the page is refreshed (e.g., changing the URL, pressing ctrl + shift + R, F5, or ctrl + R). Is it possible to specifically identify and handle only the refresh event? For instance, by comparing the current URL with the one the user intends to open and refreshing only if they are the same?

Answer №1

What you desire cannot be achieved in the traditional way as the refresh action is not catchable. However, you can implement a workaround to achieve the desired behavior:

if(self.window.name.indexOf("justAwordToNowisYourWindow")!=0){
 self.window.name = "justAwordToNowisYourWindow";
 alert( "first Load" );
}else{
  alert( "reload" );
}

To enhance best practices, consider using a timestamp to avoid unexpected behavior if multiple instances of your application are open:

var n = Date.now();
if(self.window.name.indexOf("justAwordToNowisYourWindow")!=0)
 {
 self.window.name = "justAwordToNowisYourWindow"+n;
 alert( "first Load" );
 }else{
  alert( "reload" );
}
