There's no silver bullet for this. In the past I've used cookies to record a page visit and then checked them on a subsequent visit.
What exactly is the problem you're facing?

I want to judge client is close or refresh page at client side. Then I can execute
some statements; But I can't write proper java script for most browser. So.That is exactly my problem.

The second technique (session cookies) in this article shows one way of doing it: http://www.tedpavlic.com/post_detect...javascript.php

Well you can use the onunload event. But it won't tel;l you if the user clicked the close or the refresh button, it's the same event. Perhaps you can say why you need to distinguish?

Yeah.Just like what I say. I need to execute some statements in there.
Such as, a Client log on a Bank page at the client side, but he log out doesn't through the exit button.So. We need do some thing to help him. Could u understand me?

So run some code in the onunload event. But that will still run if they refresh the page. A page refresh is a re-request of the previous URL, the HTTP protocol is fairly stateless and can't distinguish between you closing a page and then re-opening or refreshing it.

I agree, the problem like Joe said, is that HTTP doesn't remember one page request from the next. As far as the page and the browser is concerned, a refresh is no different from closing the page, because they BOTH close the page; a refresh simply navigates back to the same page, but it has no memory of ever being there. So if you want want to know if you've been here or not, you need to roll some custom Javascript to create that "memory" of being here in the page.

I would recommend writing a value to the cookie in javascript, you'd store a timestamp in the cookie with a key like "lastVisitedBankPage" when a user first navigates to the page. Then each time the page loads, check that key in the cookie and if it is set to a recent value, then you can assume they've refreshed the page. If the value is not there (they've never been to your site, or at least not since the last time they cleared their browser cache), or the value is old, you can assume they are coming back to the page for the first time.

I would NOT use the onunload method. This is the type of thing that spammers typically use to prevent someone from navigating away from their website, or to throw nasty pop ups around. That is a recipe form users who will have to turn off the computer and never visit your website again. Executing client-side scripting on unload is a major usability flaw and extremely rude into the bargain.
