$(”#chk2″).attr(”checked”,true);//打勾
if($(”#chk1″).attr(’checked’)==undefined) //判断是否已经打勾
单选组radio: $(”input[@type=radio]“).attr(”checked”,’2′);//设置value=2的项目为当前选中项
下拉框select: $(”#sel”).attr(”value”,’-sel3′);//设置value=-sel3的项目为当前选中项
$(”<optionvalue=’1′>1111</option><optionvalue=’2′>2222</option>”).appendTo(”#sel”)//添加
