我想楼主的意思应该是这样的:
<script type="text/javascript">
function hid(){
var nw = document.getElementById("newapp");
var che = document.getElementById("table2").getElementsByTagName("input");
var tui = document.getElementById("tui");
var flag=false;
for (ic=0;ic<che.length;ic++){
if(che[ic].checked){
flag=true;
break;
}
}
if(!flag){alert("请先选择应用");return false;}
if (tui.value==""){
alert("请填写推荐语")
return false;
}
else{
nw.className="none";
}
}
</script>
