The example in this article describes the way to implement an infinite loop for the Go language simulation while statement. Share to everyone for your reference. The implementation methods are as follows: This code uses the For statement as a while (true) in the C language to implement an infinite loop Copy Code code as follows: Package Main Import "FMT" Func Main () { Sum: = 0 for { Sum + +

There are roughly three ways to type PHP's infinite categories, 1, the database by setting the parent class ID to make a unique index, and then use the function of recursive calls to achieve an infinite classification; 2, database design through a specific format, and then use MySQL query key functions: Concat. Program implementation is relatively simple; 3, the third is not too understanding, as if to u

This article illustrates the infinite-level tree-shaped menu effect code implemented by Json+jquery. Share to everyone for your reference. Specifically as follows: This demonstrates the JSON tree menu, the JS Tree-level Tree menu, the introduction of the jquery plug-in, the use of recursive implementation to obtain the level of the tree data and the DOM structure, can be extended in the JSON data structure of the

Recently read an article about the JSON infinite folding menu, feel good writing, but also to study the next his code, so he also made a demo, in fact, such a menu item is our site or project navigation menu items are very common effect, especially in some E-commerce site on the upper left section, Or the navigation menu has a drop-down effect is also very common, but they are made a fixed, that is, the page code directly written dead, and then achiev

This paper illustrates the method of realizing infinite classification of php+mysql database. Share to everyone for your reference. The specific analysis is as follows: This PHP unlimited classification code more complete, including the database is MySQL, there are additions, deletions, edits, mobile functions, but also provide the database SQL table structure. The code is as follows: Copy Code code as follows: Connecting to a database $l

The example of this article describes the implementation of JS infinite-level tree navigation list effect code. Share to everyone for your reference. Specifically as follows: This is a JS to achieve an infinite level of tree-shaped drop-down navigation menu, concise and practical, with a good package of JS class, useful for you to draw on. The screenshot of the running effect is as follows: The online

This article describes the method of realizing the infinite pole classification of smarty template in PHP. Share to everyone for your reference, specific as follows: If it's in Smarty,Add one more. Copy Code code as follows: $smarty->assign (' Wuxian_class ', $AA); Just add this to the HTML page. There is also a problem to note $str must be global line, otherwise there will be errors. Extension of the

Incomplete recovery is incomplete data recovery, incomplete recovery is the same in many ways as full recovery, they have the same basic set of commands, but some other commands are added without full recovery. There are many reasons for incomplete

The essential difference between crash/instance recovery and media recovery is: Crash/instance recovery applies the redo log from the incremental checkpoint (incremental checkpoint) for the instance that needs to be recovered. Because the first condition of log coverage is to complete the logfile switch checkpoint of the relevant log, and the archive log is alway

RMAN recovery is divided into full recovery and Incomplete recovery. Full recovery, as its name implies, is to restore data based on full backup. However, in the real environment, such recovery is very useful. RMAN recovery is div

When there is a lot of scrolling content, such as setting seconds in the alarm, there are a total of 60 items. It is very painful for users to roll back from 59ms to 01ms. Therefore, when there are too many items in the list, we hope to have an infinite loop of scrolling. Ms and Ms are seamlessly linked. As shown in: Preface When there is a lot of scrolling content, such as setting seconds in the alarm, there are a total of 60 items. It is very painfu

In fact, it is not just an infinite loop. First, set the adapter to inherit the baseadapter. The structure is as follows: /*** This class describes the infinite loop listview ** @ Author: wxj * @ version: 10:40:28, January 1, July 24, 2014 */public class carnumberadapter extends baseadapter {private context; private string [] stringarray;/*** create a new instance carnumberadapter. ** @ Param mainactivity

When talking about calculus, many college graduates are a little embarrassed, indicating that all their calculus knowledge at school has been returned to the teacher. To put it bluntly, the knowledge of calculus is almost completely forgotten, and there is a lack of confidence in calculus. How did this happen? Do not speak in circles. It is best to be straightforward and not to hide. The essence of the 6.18 infinitely small release plan for the Internet is: to open a battle on the Internet (Batt
