问题 How do I display specific records only in jqGrid? For example, after a user login only select records will display according to the username that is logged in? 回答1: Oleg's answer to the dupe question is right, you should typically limit the data you send to the page from the server based on the request. It is also possible to make decisions using the grid loadComplete method: loadComplete: function (data) { if (data.rows.length > 0) { for (var i = 0; i < data.rows.length; i++) { if (

How to cycle through MySQL rows?

由 白昼怎懂夜的黑 提交于 2019-12-24 00:49:02
问题 I am trying to achieve a web PHP program that will display data from a records in a MySQL database in a HTML form. I have a couple of navigation buttons that I wish to cycle to the next and previous records in the database. My problem is, I can't seem to cycle back and forth through the records. mysql_fetch_assoc just gets one row or is only good when it comes to a while loop. Any help would be appreciated! This is what I have so far... $page = intval($_GET['page']); $limitStart = $page - 1;

When were extended records introduced?

由 倖福魔咒の 提交于 2019-12-20 02:09:47
问题 In Delphi 7, you a record was nothing more than a collection of data grouped into one location. In the last few versions, you've been able to add public and private members, methods, properties and constructors to them, treating them a lot more like objects. What version was this extended syntax introduced in? EDIT: In case anyone wonders why I'm asking, I'm trying to set up something that would be simplified quite a bit by using the extended syntax, but I want to make it backwards-compatible
