Javascript memory leak on page refresh; to fix?

I experience a memory leak in IE that occurs when the page is refreshed (as I described in this in the SO post).

All I want to know at this stage is : is there a way to “unload” a document (which can be called when the page is refreshed or closes) for the event to clear ALL? I am looking for a simple solution that will ensure that everything is destroyed to avoid leakage. Is this possible, or should I continue to study the details of the leak and fix it on the object by object?

Refresh . I may not be descriptive enough. I can’t (at least I don’t think I can) just set all my objects to null: I have event handlers for click events, etc. Therefore, the application must constantly “live” until it is closed . Also, if I then think about simply zeroing out everything in the "unload" method (called when the page exits), then should all of my objects have a global scope (on the right)? What is the best way to fix this? Is there a way to get a list of all reference objects so that I can reset them? Do I have to add every object that I use for an array in order to dereference it later?

try window.onbeforeunload or window.onunload and set the variables you use for null. or are you looking for something else?

Set your objects to zero and they will not be skipped.

check if you use a random anti-cache url parameter, this may lead to memory leaks

  • IE tries to keep all scripts loaded from the same domain in memory when you move from page to page, because there is a high probability that you will need almost the same scripts on different pages.
  • the random anti-cache parameter added to the script url makes it another script (at least caching is tricked by this)
  • since we know that IE is trying to download all possible scripts for the domain and save them
  • random anti-cache settings lead to a memory leak, because every time otherwise the same scripts have a different URL, and IE considers them to be different, and loads them again and again every time they reboot and saves them in mind.
