Hi,

 

I have two windows i'm working with. When window B opens off the parent window A. Window A has to be open all the time while window B is open. If the user closes down window A, window B need to close also.

 

I have a javascript function inside Window A that is launched on the onunload event.

 

function closePopup(){

main.close(); 
    
}

 

main is the name of window B. I keep getting error message when i load window A, it says main is undefined. So basically I want to be able to check to see window B is open before running main.close()

 

Can anyone help me?

 

Thanks

How are you opening the main window (Window B)?  Because at first blush, it sounds like you may have a slight runtime collision on your hands, where references to HTML elements are trying to be created before they actually exist in the browser.

 

main is the name of window B. I keep getting error message when i load window A, it says main is undefined. So basically I want to be able to check to see window B is open before running main.close()
