    if ( $(week_2).is(":checked") == true){var Tus = "1";}
    if ( $(week_3).is(":checked") == true){var Wen = "1";}
    if ( $(week_4).is(":checked") == true){var Thu = "1";}
    if ( $(week_5).is(":checked") == true){var Fri = "1";}
    if ( $(week_6).is(":checked") == true){var Sta = "1";}
    if ( $(week_7).is(":checked") == true){var Sun = "1";}

        $("#wifilist").val("110");//user
    }
    DisableObject("wifilist");

or

document.getElementById("starttime_h").selectedIndex=config_st_h;   

**获取select的选中的项的val

    var interface_mode_select_number_val = $("#interface_mode_select_number ").val();


 $("#ddlregtype").find("option:selected").text();

    var thisURL = document.URL;     
    var checkUrlAddOrEdite=thisURL.split('?date=')[1]; 
    //guest_21709_0011000_14400_19500
    check_url_wifi_date = checkUrlAddOrEdite.split('_');
    var config_wifi_name = check_url_wifi_date[0];
    var config_id = check_url_wifi_date[1];
    var config_day = check_url_wifi_date[2];
    var config_st = check_url_wifi_date[3];
    var config_et = check_url_wifi_date[4];

jquery判断checked的三种方法:
.attr('checked):   //看版本1.6+返回:”checked”或”undefined” ;1.5-返回:true或false
.prop('checked'): //16+:true/false
.is(':checked'):    //所有版本:true/false//别忘记冒号哦
jquery赋值checked的几种写法:
所有的jquery版本都可以这样赋值:
// $("#cb1").attr("checked","checked");
// $("#cb1").attr("checked",true);

jquery1.6+:prop的4种赋值:
// $("#cb1″).prop("checked",true);//很简单就不说了哦
// $("#cb1″).prop({checked:true}); //map键值对
// $("#cb1″).prop("checked",function(){
return true;//函数返回true或false
});
//记得还有这种哦:$("#cb1″).prop("checked","checked");

if ( $(schedule_enable_id).is(":checked") == true){var schedule_enable = 1;}
