I am trying to fire a event from script inside aspx page. To fire a event I am using Event.observe() method. In that line I am getting error like "Event is not an object". Please help me inthis issue.Thanks in advance.

My code:

 function Submitkeyword() {
        obj = document.getElementById("select");//select is button id
        Event.observe(obj, 'change', function () {
            var e = document.getElementById("lookupvaluesDropdown");//lookupvaluesDropdown is dropdownlist id
            var valueddl = e.options[e.selectedIndex].value;                
        });
        fireEvent(obj, 'submit'); 
        window.close(); //To close the popup window
    }
    function fireEvent(element, event) {
        if (document.createEventObject) {
            // dispatch for IE
            var evt = document.createEventObject();                 
            return element.fireEvent(event, evt);
        }
        else {
            // dispatch for firefox + others 
            var evt = document.createEvent("HTMLEvents");
            evt.initEvent(event, true, true); // event type,bubbling,cancelable 
            return !element.dispatchEvent(evt);
        }
    } 



Question: Congenital blindness due to retinitis pigmentosa - does it exist?
Answer: I have only ever heard of one case where RP caused blindness in a newborn. Unfortunately, I am unable to release the name or any details of the patient because of privacy issues and so forth. 

Usually blindness from RP comes after a few years of life (as you said), making blindness from birth (or even early infancy) very rare. 

I can tell you, however, that the formerly stated patient suffered from type I Usher Syndrome, if I remember correctly. I apologize for my inability to provide you with more specific details on this.

I don't know how much this will help in your search, but I sincerely hope that it does.
