高手们帮我看看下面的代码。这主要实现鼠标移上去和移出去改变图片透明度吧？我也不知道。我是搞程序的，这个了解不多。。

这个是我们公司网站的这个脚本出错的页面。我不太懂，只好问问大家了。好像是下面代码的错误。。大家帮忙看看。

就是这个页面报的错。我想应该是下面的代码，如果不是，请大家帮忙找找



<script type="text/javascript" language="javascript">

        nereidFadeObjects = new Object();

        nereidFadeTimers = new Object();

        function nereidFade(object, destOp, rate, delta) {

            if (!document.all)

                return

            if (object != "[object]") { 

                setTimeout("nereidFade(" + object + "," + destOp + "," + rate + "," + delta + ")", 0);

                return;

            }

            clearTimeout(nereidFadeTimers[object.sourceIndex]);

            diff = destOp - object.filters.alpha.opacity;

            direction = 1;

            if (object.filters.alpha.opacity > destOp) {

                direction = -1;

            }

            delta = Math.min(direction * diff, delta);

            object.filters.alpha.opacity += direction * delta;

            if (object.filters.alpha.opacity != destOp) {

                nereidFadeObjects[object.sourceIndex] = object;

                nereidFadeTimers[object.sourceIndex] = setTimeout("nereidFade(nereidFadeObjects[" + object.sourceIndex + "]," + destOp + "," + rate + "," + delta + ")", rate);

            }

        }

    </script>
