单选按钮只能选中一个
function test(){
var oRadio=document.getElementsByName("infoclass");
var id ;
for(var i=0;i<oRadio.length;i++){
if(oRadio[i].checked){
id = oRadio[i].value;
location.href = "clerk_detail.do?emp_id=" + id;
return true ;
}
}
alert("请选择您要查询的信息！");
return false ;
}
要保证复选框组的name相同，单选按钮组的name也相同
