javascript - Session lost window.location.href - Stack Overflow

I'm trying to redirect the user to another page width:

window.location.href = "url here" //relative link

but when I do, it clears my sessvars.keyPageArray variable. Anyone know how to keep a session variable after a redirect?

This is the sessvars library that I am using: .html

UPDATE: I used google chrome debugger and my script actually does work. For some crazy reason it only works if I'm monitoring it variable by variable but not when I simply run it normally without the debugger on? Why is that happening?

Just because you named a variable sessvars doesn't make it so. Use localStorage, sessionStorage or cookies depending on your need.

All javascript context is unloaded and lost when the browser navigates to another page.

Example using localStorage:

window.onbeforeunload = function() {
    localStorage.setItem( "session", JSON.stringify( window.sessvars) );
};

window.onload = function() {
    window.sessvars = JSON.parse( localStorage.getItem( "session") || "{}" );;
};

Sessions are on the server side.

Nothing to do with the browser.

JavaScript doesn't keep data after the page is closed, to open anoher page, or eaven on refresh. Eventualy you can store data in cookie.

One important thing causing the problem is when in server /phptmp directory does not exist or does not have writing permissions.
