|zyciis| 为什么 onkeydown="SetFocus(event,'txtManagerPass')" 我的js无效

 function SetFocus(winevent,obj) 
        { 
var winevent=window.event||winevent;
            if(winevent.keyCode==9) 
            {                
                winevent.keyCode=null;        
                document.getElementById(obj).focus();                
            } 
        }

    汗，好像已经没有其他简便写法了…
    //有的话，只有去掉window，某些程度上都一样
     function SetFocus(winevent,obj) 
            { 
            var winevent=event||winevent; 
                if(winevent.keyCode==9) 
                {                
                    winevent.keyCode=null;        
                    document.getElementById(obj).focus();                
                } 
            }

    IE8下测试通过！按下tab建，要离开焦点的那个框继续被选中焦点！
