//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;
}
}
}
