Angular2 custom paging component, angular2 custom Paging
In the project, parameters sent from the frontend to the backend are as follows:
PageSize: number of entries per page
PageNo: Current page number
For example, if there are currently 1st pages and 20 records on each page, the background returns 20 records on 1st pages (SQL should use limit to retrieve paging

Paging is generally used together with a table. A paging link is used as a part of a table. It is reasonable to encapsulate a paging link into an independent component and then embed it into a table component as a chi
In my new function of using SQL Server2005 to construct a paging stored procedure, I mentioned using the Row_number () function instead of top to implement the paging stored procedure.
But the time is long, and found a new problem, is the master table paging query. For example: order form and order list, request is Inquiry order, second page, 10 per page
Before the user thinkphp do paging encountered some paging problem; search conditions are brought into pagination:
$map [' article_title '] = UrlDecode ($_get[' article_title ']);
$date _sosuo[' article_title ' = Array (' Like ', '% '. $map [' Article_title ']. %');
