How to run function of parent window when child window closes

Question

I am calling the javascript window open   function to load another url in a pop up  Once the users is finished it takes them to the last page that has a link that says close window that calls the window close   function  Now when that page closes I need to update something in the original page that opened the window  Is there any way to do this  I have to call a function that is in my original page

You probably want to use the  onbeforeunload  event   It will allow you call a function in the parent window from the child immediately before the child window closes   So probably something like this   window onbeforeunload   function  e        window parent functonToCallBeforeThisWindowCloses

The answers as they are require you to add code to the spawned window  That is unnecessary coupling      In parent window var pop   open url   pop onunload   function          Run your code  the popup window is unloading      Beware though  this will also fire if the user navigates to a different      page within thepopup  If you need to support that  you will have to play around      with pop closed and setTimeouts

I know this post is old  but I found that this really works well   window onunload   function         window opener location href   window opener location href       The window onunload part was the hint I found googling this page   Thanks   jerjer

You can somehow try this   Spawned window    window onunload   function  e        opener somefunction      or     opener document getElementById  someid   innerHTML    update content of parent window        Parent Window   window open  Spawn htm       window somefunction   function         You should not do this on the parent  otherwise opener somefunction   will not work  doing window somefunction makes somefunction as public   function somefunction

This is an old post  but I thought I would add another method to do this   var win   window open  http   www google com     var winClosed   setInterval function           if  win closed            clearInterval winClosed           foo      Call your function here           250     You don t have to modify the contents or use any event handlers from the child window

Along with jerjer answer top   sometimes in your parent window and child window are not both external or both internal you will see a problem of opener undefined  and you cannot access parent page properties  see window opener is undefined on Internet Explorer
