My program has a main window and a popup. When I put onclick or onsubmit events in my program to call a function in the main window, it calls using the window.opener method. Once inside the main window function, I would like to write to the popup.But the function does not work…eg. dispwin.document.write(“Hi”) doesn’t work. instead im able to use something like alert(“Hi”) in the function. this doesn’t help.
