How to detect browser refresh event in javascript

I was once asked to add a feature to the highlighting script so that highlighting would be turned off when a page was refreshed. I could not think of a simple way to detect when a page was refreshed, and when I searched on-line I found that not many other people had come up with good solutions to this problem.

I ended up coming up with my own way to detect refreshes using cookies and implemented the search highlighting script so that refreshes would toggle highlighting on and off. See the highlighting script for more details. Here I give a common method using JavaScript and hidden form variables which I did not use as well as a unique as far as I can tell method that uses JavScript and cookies that I did use.

In most web browsers, hidden form variables are maintained across refreshes. That is, even though a page is refreshed, if a hidden form variable was changed by JavaScript before the refresh, the changed value will be used after the refresh.

Thus, on a page load JavaScript can check to see if a hidden variable that defaults to being unset is set. If it is unset, it assumes this is not a refresh and it sets it. If it is set, it assumes this is a refresh. However, the implementation of this seems to change from web browser to web browser and even from version to version. In some web browsers, this works with a refresh but it does not work with a reset a "shift-refresh" while in others it works with both.

Plus, the bulk of the coding for this method is buried in the body of the web page rather than in JavaScript that can be included in a single line in the header.

I prefer not to use the above method. For one, its behavior is libro digital food marketing to vary from web browser to web browser.

Additionally, it requires a bulk of code in the body of the web page. So I use JavaScript cookies. On a page unload, the web page sets a cookie to the name of the web page and another cookie to the current time in seconds. Then, on page load, the web page retrieves those cookies and checks the current time. If the name cookie matches the name of the page and the time cookie differs by the current time by no more than 5 seconds, then the load is assumed to be a refresh.

Otherwise it is assumed to be a fresh load. In the case where the page posts data back to itself, it can prevent the setting of artisan v1.0 cookie so that the next load won't look like a refresh. This method is longer, but I believe it is tighter and more robust. The above example is long and there are chances that it will catch some false positives, but in my experience it is more consistent than other solutions.

Additionally, nearly all false positives can be prevented with the disableRefreshDetection function. However, there are still times when a page reset may be needed and most page resets will look like page refreshes to this script as well.

Note that the first method that uses hidden variables can still have this same problem depending on the web browser. Click Here for Printable Version. Motivation I was once asked to add a feature to the highlighting script so that highlighting would be turned off when a page was refreshed.

In this script you can then so whatever you want. Just to clarify though, the pressing of the refresh button cannot be detected per se. If they match, then it was a refresh, and appropriate action can be taken.

I have a cunning plan…! At the top of every script, set the session timeout to 30mins or whatever you want it to be normally. Then, use the onunload or onbeforeunload events in conjuction with the JSRS library that I gave the URL for earlier to call a script which sets the session timeout to one minute or so. You then need to catch the session expiry event however you do it in PHP and call your log out code when it occurs. Thus, if the user is leaving the site by closing the window, or navigating to another sitethen his session expires one minute later.

The problem I am facing is that this plugin does not seem to detect if the user has refreshed the page. This code is executed each time the user moves forward or back in the browser history. I would also like it to exexute when the user refreshes. A naive attempt of mine would be to simply store the current state into some cookie after each change and simply load them again on each page load. Along these lines, I had a page whose behavior I didn't want to repeat if refreshed, so I changed the hash programmatically as described in this answer.

I found that at least Mobile Safari would ignore the hash if the refresh occurred automatically e. I ended up using a more complex solution described here. On a page refresh, the javascript is also reloaded. So couldn't you specify what you want to happen directly in jQuery's ready method?
