select 动态加载，选中后切换到当前选项，url跟随改变

 

 

 //加载消息类型
            $.get("@Url.Action("MasterList")", {}, function (data) {
                if (data.list != null && data.list.length > 0) {
                    $("#mType").html("").append("<option value=\"0\">请选择</option>");
                    var params = GetUrlParams();
                    $.each(data.list, function (i, item) {
                        if (params.typeId == item.typeId) {
                            $("#mType").append("<option selected=\"selected\" value=" + item.typeId + ">" + item.name + "</option>");
                        }
                        else {
                            $("#mType").append("<option value=" + item.typeId + ">" + item.name + "</option>");
                        }
                    })
                }
            });
