Send a refresh request to another page opened in the browser

Question

I have page A that creates a window with the page B.

Page B asks the user some datas, inserts them in the database and then closes itself. After the insertion, I'm trying to make page A refresh automatically (it can be both from A seeing that B has closed, or by a function triggered by B itself before (or after?) closing)

How can I do that?

possible through JavaScript `window.onclose`, no? Or you trying to do this through PHP only? — BlitZ, May 31 '13 at 08:39
Well maybe, but how can I address page A in this way? (both php or javascript are ok, editing tag) — Mewster, May 31 '13 at 08:40

JavaScript's window.open() returns reference to the instance of opened window. You may use it to set up onunload event handler, like this:

var hWndB = window.open('somepage.php'),
    hWndA = window.self;

hWndB.onunload = function(){ hWndA.location.reload(); }

You can use the onunload event and window.opener. For example.

window.addEventListener('unload', function() {
   window.opener.location.reload();
}, false);

Or you could use jquery so you wouldn't have any crossbrowser compatibility problems:

$(window).on('unload', function() {
   window.opener.location.reload();
});

Also there is another event called onbeforeunload that you might want to take a look at.

EDIT

For older browser you can use the hack that @CORRUPT has provided in the comments: window.open() returns undefined or null on 2nd call

`window.opener` is not reliable in some [***cases***](http://stackoverflow.com/questions/960293/window-open-returns-undefined-or-null-on-2nd-call). – BlitZ May 31 '13 at 08:49

Variant "A seeing B closed":

//winb is global variable
winb=window.open(blah blah); //Existing: A opens B

window.setTimeout(checkWinB,1000);

function checkWinB() {
  if (winb.closed()) refreshMySelf();
  else window.setTimeout(checkWinB,1000);
}

Variant "B kicks A":

opener.rerfreshMySelf();
window.close() //Existing: B closes

Both variants need the refreshMySelf() function to refresh the page. How to do this depends on the page mechanism, but a starting point for a non-AJAX page is

function refreshMySelf() {
  location.reload();
}

Send a refresh request to another page opened in the browser
