Javascript: onrefresh or onreload?


I want an event handler that fires when the user hits reload. Is onrefresh or onreload the correct handler to add to ? Also, will this even fire before or after onunload? Are there an browser inconsistencies? Thanks.


Answers:


I don't think there are events called onrefresh or onreload. You can know when the page is unloading, but knowing why (i.e. where the user is going next) is outside JavaScript's security sandbox. The only way to know whether the page has been reloaded is to know where the user was on the last page request, which is also outside the scope of JavaScript. You can sometimes get that via document.referrer, but it relies on the browser's security settings to permit access to that information.
