Online lottery program on many sites, many lottery forms, flash sweepstakes, this article will introduce you to the jquery carousel draw, combined with code examples will use jquery and ASP to realize the Carousel Lottery program, in order to facilitate understanding, the article posted to realize the source code as a share. By rotating the dial hand to complete a lottery draw form, according to the angle of rotation to control the position of the pointer--lucky big turntable.

2. Default.aspx page code

<span style= "Font-family:microsoft yahei;font-size:14px;" ><%@ page language= "C #" autoeventwireup= "true" codefile= "Default.aspx.cs" inherits= "_default"%><! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
We build the Custom Function lottery (), in lottery () we send a POST request to data.php, if the winning information is successfully returned, the call rotate plug-in starts to turn, the rotation angle is determined by the angle returned from the background, here we use the 2880+ A is the angle of rotation, that is, the pointer rotates 8 laps +a, and then we call Lottery () when we click on the "Start Draw" button, so the carousel draw is complete.
