Infinite classification is a problem that will be encountered in all program development, let me introduce the php+mysql implementation of an infinite class of classification procedures, the need for friends can refer to. Here's a look at my database structure: The database name is: fa_category Field Type Comment Cid Int (11) Category ID Catename varch

Infinite Carousel (recycling)I. Infinite Carousel1. Brief descriptionIn development, it is often necessary to automate the carousel of ads or some images, which is called infinite scrolling.　　In development, it is common practice to use a uiscrollview, add multiple ImageView on the Uiscrollview, and then set the ImageView's picture, and the ScrollView scroll rang

Infinite class classification, mainly by storing the ID of the parent classification and the classification path to achieve. Since the structure of the data is simple, I can only think of the recursive way to show the relationship of the classification to the tree. Infinite class classification, mainly by storing the ID of the parent classification and the classification path to achieve. Because the structu

Implementation of image carousel Effect The main idea is to set the size of the ScrollView based on the total number and width and height of the image.

PHP Recursive implementation of infinite class classification In some complex systems, it is required to classify the information columns infinitely, in order to enhance the flexibility of the system. So how does PHP implement an infinite class classification? We use recursive algorithms in this article and combine MySQL data tables to achieve infinite classific

Infinite pole classification is often used in development, for example: Department structure, article classification. The difficulty with infinite pole classification is "output" and "query", for example Output the category of the article as a Find the articles that are included in all categories under Category A. 1. Principle of implementationThis article introduces several common method

Treetable achieves an infinite hierarchy and a better presentation hierarchy by combining row and column merging of cells. 1. Build a id/pid/name array of dynamic data that can be generated later by the database. Tree algorithm please click Copy Code code as follows: Array * 1 => Array (' ID ' => ' 1 ', ' ParentID ' =>0, ' name ' => ' one-level column one '), * 2 => Array (' ID ' => ' 2 ', ' ParentID ' =>0, ' name ' => ' one-level

Objective In fact, think carefully about the principle is quite simple. It's just when we slide to the last page and then slide backwards to the first page, and when we slide to the first page and slide forward, we navigate to the last page. However, I believe many friends have encountered this problem: the view of the excessive effect is not natural. Small series is also through Baidu and Google to find a lot of solutions, experimented with a lot of methods, summed up a relatively good metho
