使用命令关闭窗口并重新加载父页面后，如何在重新加载后自动弹出div？

Question

The flow is as this:

1. User clicks register button, opens up a registration page using the window.open command.

2. User gives their details to the page and submits.

3. Upon submit it sends the details to the database and then closes the popup window using

    onsubmit="refreshWelcome()" //used in the form function refreshWelcome() { //closes pages and reloads welcome page again. window.opener.location.reload(); window.close(); } 

4. On Return to the parent, I'd like a message to popup saying Registration complete just before the login area.

I am unsure how #4 can be done and is it possible? Welcome_page has the button goes to - Registration page popup - Registration submits data using another php page regprocess.

Did I clarify what im looking for or do you need more information?

Answer 1

You can assign an event handler to the closing event fired by the window.

Let's say your window is opened like this:

var registrationWindow = window.open(url);

You can then bind a callback to the onbeforeunload event, for example:

registrationWindow.onbeforeunload = function(){
    /... your code here .../
}

Make sure that your opened window url is located on the same domain as your parent window, otherwise this won't work.
