偶尔在看天天基金网净值公告时，从源代码里剥下的一段js代码，感觉比较实用，分享一下(仅IE有效)：

<script  type="text/javascript">
var highlightcolor='#E0F2FE';
var clickcolor='#ffedd2';

function  MouseOver(){
    var source=event.srcElement;        
    if  (source.tagName=="TD"){        
        source=source.parentElement;
        var cells  =  source.children;    
        if  (cells[0].style.backgroundColor!=highlightcolor&&cells[0].style.backgroundColor!=clickcolor)
            for(i=0;i<cells.length;i++){
                cells[i].style.backgroundColor=highlightcolor;
            }        
    }
}

function  MouseOut(){    
    var source=event.srcElement;
    if  (source.tagName=="TD"){    
        source=source.parentElement;
        var cells  =  source.children;    
        if  (cells[0].style.backgroundColor!=clickcolor)    
            for(i=0;i<cells.length;i++){
                cells[i].style.backgroundColor="";
            }        
    }
}

function  MouseClick(){
    var source=event.srcElement;
    if  (source.tagName=="TD"){    
        source=source.parentElement;
        var cells  =  source.children;
        if  (cells[0].style.backgroundColor!=clickcolor)
            for(i=0;i<cells.length;i++)
                cells[i].style.backgroundColor=clickcolor;            
        else
            for(i=0;i<cells.length;i++)
                cells[i].style.backgroundColor="";    
    }
}
</script>
