JavaScript imitation static paging implementation method_javascript skills
The example in this article describes the implementation method of JavaScript imitation static paging. Share it with everyone for your reference. The details are as follows:
This is based on JavaScript to imitate the function of web pages without refreshing static paging. It is estimated that some changes will be made when it is actually used, because the content that needs to be paginated is currently stored in JS as a string variable. When used, the data here needs to be turned into a database. The data read from , I don’t know how practical it is. Friends who need it can adjust it slowly.
The operation effect is as shown below:
The specific code is as follows:
<HTML>
<HEAD>
<TITLE> 静态分页</TITLE>
<style>
* {
font-size:10.2pt;
font-family:tahoma;
line-height:150%;
