//一个或者多个没选，则全选按钮不被选中,全选之后则全选按钮自动选中
     function SelectOne(dh2){
         var selCount = 0;
         var unSelCount = 0;
         var ch = document.getElementsByName(dh2);
         var all=document.getElementsByName(dh2)[0];
         for(var i=1;i<ch.length;i++){
             if(ch[i].checked==true){
              selCount++;
             }
             if(ch[i].checked==false){
              unSelCount++;
             }
             if(selCount==ch.length-1){
              all.checked=true;
             }
             if(unSelCount>0){
              all.checked=false;
             }
        }
     }
