paging

问题 I managed to get pagination working like described here. The problem is I need to expose an API which would look like this: getUsers(pageSize, pageNumber) , which does not really go well with the way JNDI/LDAP does the paging(with a cookie you pass each time to the search method). The code looks like this: private NamingEnumeration ldapPagedSearch(String filter, int pageSize, int pageNumber){ InitialLdapContext ctx = getInitialContext(); //TODO: get the id also, need to spec it in UI //

问题 I have this schema: article: { subject, comments: [] } if I have 8 comments, and query article.find({}, { comments: { $slice: [ -10, 5 ] } }); And I get comments from index 0 to index 4, but I only want comments from index 0 to index 2 to be returned because of paging. (page 1 $slice[ -5, 5 ] from index 3 to index 7, page 2 $slice[ -10, 5 ] from index 0 to index 2) now I have to pass another parameter "lastId" to compare each comments and remove that "_id" < "lastId", but I think it is a

问题 Can anyone point me in the right direction to figure out a way to fix the way paging and orderBy work together in Angular? Currently, I can orderBy and page the results of the data[], but the orderBy filter only affects the each page individually. For example, if I sort in reverse order by ID, page 1 will list 10-1, and page 2 will list 15-11, as opposed to starting with 15 and going to 1 by the end of the second page. I have a basic fiddle here http://jsfiddle.net/ZbMsR/ Here is my

问题 Say we have a certain parent process with some arbitrary amount of data stored in memory and we use fork to spawn a child process. I understand that in order for the OS to perform copy on write, the certain page in memory that contains the data that we are modifying will have its Read-only bit set, and the OS will use the exception that will result when the child tries to modify the data to copy the entire page into another area in memory so that the child gets it's own copy. What I don't

问题 I have a JSON result that contains numerous records. I'd like to show the first one, but have a next button to view the second, and so on. I don't want the page to refresh which is why I'm hoping a combination of JavaScript, jQuery, and even a third party AJAX library can help. Any suggestions? 回答1: Hope this helps: var noName = { data: null ,currentIndex : 0 ,init: function(data) { this.data = data; this.show(this.data.length - 1); // show last } ,show: function(index) { var jsonObj = this

问题 I have a search screen where the user has 5 filters to search on. I constructed a dynamic query, based on these filter values, and page 10 results at a time. This is working fine in SQL2012 using OFFSET and FETCH , but I'm using two queries to do this. I want to show the 10 results and display the total number of rows found by the query (let's say 1000). Currently I do this by running the query twice - once for the Total count, then again to page the 10 rows. Is there a more efficient way to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . Is there any library that can be used to implement paging for a list? Let' assume I have a space of 10 lines, and the user can select if he wants to scroll forward or backward by page (thus +- 10 items). This might eg be controlled by -1, 0, +1 . This is probably much work to build a class that prevents

问题 is there some elegant way, ideally with jquery plugin like pager 1 or pager 2 how to implement paging with asp.net mvc? I am trying to go over partial views, but so far unsucessfully. Where should I store the loaded grid data? And how to respond on the page selection with just a partial refresh? Thanks in advance. 回答1: Try this article out, looks pretty handy - he uses a custom Html extension method. Also, check this SO question. 回答2: The MVC Contrib Grid comes with paging functionality.

问题 When using SetFirstResult(start) and SetMaxResults(count) methods to implement paging I've noticed that the generated query only does a select top count * from some_table and it does not take the start parameter into account or at least not at the database level. It seems that if I instruct NHibernate to execute the following query: var users = session.CreateCriteria<User>() .SetFirstResult(100) .SetMaxResults(5) .List<User>(); 105 records will transit between the database server and the
