paging

问题 I have custom directive to load pages inside a div .directive('page', function () { return { templateUrl: function (elem, attr) { return 'pages/page-' + attr.num + '.html'; } }; }); here is the dom representation of the custom directive <div page num="{{pageNo}}"></div> Here i want to change the page number from the controller. Directive works fine if the value added directly <div page num="1"></div> 回答1: As you want the interpolated value of pageNo inside your directive, You cant get that

问题 I have a few questions regarding paging a Ext Store. The Store will pull an amount of historical data on page load. If the number of records is greater than 10 then I need to implement paging on a custom component/view. The view will be generated with Ext.view.View and a XTemplate. I would like to know if i can use the paging toolbar on a custom component and if i can query a Store where all the data is held locally. Therefore, not passing parameters to the server and pulling new data back

问题 I am looking at reworking our website's reporting pages to be faster, and I am on the fence about how I should implement paging. Our database is large, > 150 million records. Most of our reports require complicated data that comes from up to 5 to 10 tables so each may have 5 or 6 joins and some inner selects. Obviously, they are not fast queries. To implement paging on the database side, for each web request, I need to query the database for the rows for the current page (say 100 of 10,000),

问题 I want to be able to remove a page from page cache so that next access to this page (by any process) will trigger a page fault. I'm doing this from the kernel, and I have a pointer to struct page I wish to remove. Deleting from page cache is easy (done by __delete_from_page_cache() ), but I don't know how to "unmap" this page from all processes mapping it into their VMAs. I tried using try_to_unmap(my_page, cpu_page, TTU_UNMAP|TTU_IGNORE_MLOCK|TTU_IGNORE_ACCESS) from rmap.c but it doesn't

问题 I have a query with a left join in it: var query = (from v in context.Vehicles //left join vehicleAttributes join va in context.VehicleAttributes on v.VehicleId equals va.VehicleId into vAttributes from vehicleAttributes in vAttributes.DefaultIfEmpty() where v.FleetId == fleetId select new { v, vehicleAttributes }); And now I need to do a paging on it. this works but gets all rows, so much more than i actually need query.ToList().Select(x => x.v).Distinct().Skip(10 * (page - 1)).Take(10)

问题 I am using the PagedList library in my app. It all works as expected, using the PagedListAdapter. However, I am not able to find how I can get a callback and be notified that the PagedList has been updated. At list's ItemKeyedDataSource is used to fetch the list's data from the network. At that point, the PagedListAdapter's submitList is called, providing a PagedList of length 0. When the DataSource has fetched the data from the network, its callback.onResult() is executed and the list's UI

Everything works fine but when I try to do paging, I need to

问题 This is a followup on the question: ASP.NET next/previous buttons to display single row in a form As it says on the page above, theres a previous/next button on the page, that retrieves a single row one at a time. Totally there's ~500,000 rows. When I "page" through each subscribtion number, the form gets filled with subscriber details. What approach should I use on the SQL server? Using the ROW_NUMBER() function seems a bit overkill as it has to number all ~500.000 rows (I guess?), so what
