I have localstorage for employeeid stored.When i refresh the browser get local storage value like employeeid based on employeeid get some data.when i close the browser i want to clear employeeid in local storage by using angularjs or javascript. I tried the following code.
window.onunload = close;
function close() {
//// do something...
localStorage.clear();
return null;
}
In the above code when i refresh the browser that time also window.onunload fired and clear the local storage values, but i want to clear local storage at the time of browser close only.
If you do not need this to work across different windows/tabs, then you should use sessionStorage
instead of localStorage
.
Where what you store into localStorage
is “permanent”, sessionStorage
stores values only until the window/tab is closed, similar to a “session cookie”, that is set without any lifetime – that will live only until the browser is closed (but will be available across different tabs when your site is open in more than one.)
A few more details can be found in these questions:
What is the difference between localStorage, sessionStorage, session and cookies?
