#site-nav .menu-hd { PADDING:0px; DISPLAY: block; Z-INDEX: 10002; CURSOR: pointer;  POSITION: absolute; HEIGHT:50px; line-height:40px; width:76px; margin:0;}#site-nav .menu-c { PADDING:0px; DISPLAY: block; Z-INDEX: 10002; CURSOR: pointer;  POSITION: absolute; HEIGHT:50px; line-height:40px; width:90px; background:url(img/catalog.png) no-repeat center top; margin:0;}#site-nav .menu:hover .menu-hd { height:50px; width:90px; background:url(img/catalog.png) no-repeat center top;}

function catalogClick(logType,pageCode,id) {
var obj = document.getElementsByTagName("a");
for(var i=0;i<obj.length;i++) {="" if(obj[i].classname="=" 'menu-c')="" obj[i].classname="menu-hd" ;="" break;="" }="" id="trim(id);" var="" thisobj="document.getElementById(id);" eval(id).classsname="menu-c" ;}function="" trim(str)="" if="" (str="=" null)="" return="" "";="" str.replace(="" ^\s*(.*?)[\s\n]*$="" g,="" "$1");}<="" script=""></obj.length;i++)>

回复讨论(解决方案)

 eval(id)==> thisObj

把
eval(id).class sName="menu-c";
改成
thisObj.className="menu-c";

className你多写了个s

多谢，我还以为是语法上不支持这样的操作呢
