I am an experienced programmer but new to web apps including Javascript. An instructor gave our class the code needed to create rollover button effects: In the PAGE HEADER: <head> | | <!-- Following script required for Navigation Bar --> <script type="text/javascript"> <!-- navImage0 = newImage(); navImage1 = newImage(); navImage2 = newImage(); navImage3 = newImage(); navImage4 = newImage(); navImage5 = newImage(); navImage6 = newImage(); //--> </script> | |</head> On the IMAGE/LINK: <body> | | <a href="../services.shtml" title="Go to: Services at Specific Computer Systems" onmouseover="navImage1.src='../img/buttonServicesOver.png';" onmouseout="navImage1.src='../img/buttonServicesNormal.png';" onclick="navImage1.src='../img/buttonServicesDown.png';" onmousedown="navImage1.src='../img/buttonServicesDown.png';" onmouseup="navImage1.src='../img/buttonServicesOver.png';" > <img id="navImage1" src="../img/buttonServicesNormal.png" alt="Button: Go to Services Page"> </img> </a> | |</body> That is ALL of it! This Code Works but I don’t understand why. This became an issue because this code causes an “Object expected” error at the first character of “navImage0 = …” in the header. This error does NOT appear to have any affect on the function of the page including the rollovers. This error appears to occurs only in IE. In trying to diagnose this error I discovered several different (but similar) methods for implementing rollovers. I understand them fine, but they exposed just how much seams to be missing from the solution demonstrated by our instructor. The function “newImage” is NOT defined in any place that I can find. Please can someone tell me why/how does this simple solution work? ThanksRoss
