Recently, when my colleagues were working on a project, they needed an animation library to support the following requirements: Can start, pause (linear, non-linear tween support), continue, end Supports parallel processing of multiple styles It is better to run without relying on a framework The smaller the file size, the better. He looked for some existing plug-ins or libraries that could hardly meet or be balanced. At this requirement, I wrote a relatively

Analysis: We use a file (Data.dat) to store voting columns. Each column occupies one row. This way, you can add and subtract the columns you want to vote for. We then use a file (Votes.dat) to store our poll results. And record the latest voter's IP address, simple to prevent more than one person to vote. Therefore, you should build your own two files in the program directory Data.dat and Votes.dat Program Run Process part The program should run with

This paper illustrates the method of JS simulating simple scroll bar effect. Share to everyone for your reference, specific as follows: Use JS to simulate the scroll bar. Easy mode, similar to the common scroll bar on the phone. The effect is as follows: The JS code is as follows: var scrollmoveobj = null, Scrollpagey = 0, scrolly = 0; var scrolldivlist = new Array (); Obj needs to add scroll bar
