Hi, I have created a program in IE.
OnBeforeUnload or OnBeforeClose code is used to close database connection and update a few things.
The code for these never finishes fully when the user hits the X button of the browser.
Unless i place an Alert(""); then it will not finish executing the code.

Does anyone know a way around this? I have been stuck on this for so long and cant find any help anywhere.:confused:

Thanks

I think the best possible way would be to check if the user changed anything. If so then store this and confirm that the user really wants to exit the page. Something like:

JavaScript

function beforeClose(){
    if(inputChanged){
        // ... save data here
        return 'Are you sure you want to navigate away?';
    }
}

Above also looks kind of user friendly. I also was thinking about something else but I haven't tested this. The idea is to setup a timer and return false and let the timer event handle the saving and closing of the page. You probably will need a global variable to keep track if saving is already done, otherwise closing will never work.

var isSaved = false;

<body onbeforeunload="if (!isSaved) {setTimeout('handleWindowClose();',50);return false;}">

function handleWindowClose()
{
  // Save data
  isSaved = true;
  // Close window
}

Good luck!
