Of course, my most concern is the second code of this method: s=3*n-(3-i). There is the Ajax success event in which they used History.replacestate ({page:999}, "", "#" +s); Change the address URL and the page does not refresh. The HTML5 API adds Pushstate () and Replacestate (). What does n mean? What is the value of I?n is the page number of the Oita page. The se

Although we can no longer run software containing malware, once we run it, it may infect all PE files on the computer, in this way, even if we use the antivirus tool to clear the bad behavior caused by the virus, once other programs run, the virus will continue again.

A preliminary study on the implementation of PHP in MVC Classic mode. Implementation of MVC php (as the mainstream development language) Author: HarryFuecks translation: EasyChenMVC mode is very common in website architecture. It allows us to build a three-tier MVC mode php (as the mainstream development language) implementation 　　 Translated by Harry Fuecks The

Here's how to use it:Rangeobj.insertnode (node);The following demo

A Study of PHP variables One feature shared by each programming language is the storage and retrieval of information; PHP is no exception. While many languages require all variables to be defined before they are used, and their type information is fixed, PHP allows programmers to create variables when they are used, and can store information that can be expressed in any type of language. You can also conve
