How to handle onload javascript alerts in selenium?

It is not being captured in Selenium IDE neither it is being handled by getAlert() function.

Even I faced the same problem. After several hours spent with selenium, found the solution for handling java script alerts and popups.

we can use the keyPressNative of selenium to handle the java script alerts from the selenium RC.

Here is how the key*Native() method have to be used:

    selenium.keyPressNative("27"); // Escape
    selenium.keyPressNative("10"); // Enter    
    selenium.keyDownNative("16"); // Press and do not relase the shift key, so that
    selenium.keyPressNative("79"); // this character will be capitals
    selenium.keyUpNative("16"); // Release the shift key, as we don't need it for the 
    selenium.keyPressNative("67");

It is not advisable but helped me in handling some of the selenium failures.
