IE6 图片轮换效果JS报类不能支持automation操作

JScript code

    function cleanallstyle() {        for (i=0;i<7;i++) {        document.getElementById("focus_"+i).className = "" ;        }    }    function show_focus_image(index) {             clearTimeout(refreshHotQueryTimer);        setHotQueryList(index);        refreshHotQueryTimer = setTimeout('refreshHotQuery();', 5000);    }    function setClick() {        clearTimeout(refreshHotQueryTimer);         }    var refreshHotQueryTimer = null ;    var hot_query_td =  document.getElementById('HotSearchList');    setHotQueryList(CurrentHotScreen);    refreshHotQueryTimer = setTimeout('refreshHotQuery();', 5000);

调用<a onmouseover="show_focus_image(" + j + ")" href="#target="_blank" blockid="931">文字</a>在IE6下报类不能支持automation操作，求解释

[解决办法]
