jQuery simple and practical carousel implementation method

This article mainly introduces in detail the simple and practical carousel production method in jquery. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

WEB development is often used in a situation where the items in a container are played and displayed in a loop, and there are corresponding navigation bar prompts, because this can be used in many places, and the functions are very similar. So write a playback function like this and share it. It should be noted that this requires the support of jQuery. You can search and download it online. The following is summarized as follows. Look at the code directly.

1. Save the following as An independent file itemPlayerApp.js:

//attend: this need jQuery.js support 
var itemPlayerApp={ 
 author:'shenzhenNBA', 
 version:'v1.0', 
 appMaxNum:0, 
 playData:'1xplay', 
 playerID:"", 
 speed:3000, 
 appPlay:function(){  
  var f=this.playData.toLowerCase().split('x'); 
  if(f[1]=='play'){ 
   var i; 
   try{i=parseInt(f[0]);}catch(e){i=0;} 
   if(i>=this.appMaxNum){i=0;}    
   this.appTab(i);   
   this.playData=(++i)+"xplay"; 
  }   
 }, 
 appTab:function(tabIndex){ 
  var k,j; 
  try{k=parseInt(tabIndex);}catch(e){k=0;}   
  for(j=0;j

//B, The ID composition of the navigation container should be the main container ID plus NavCon, as above containerIDNavCon; 
//C, The ID composition of each A element in the navigation container is, itemNav Add an increasing number sequence starting from 0, as shown in the green part above; 
//D, display the ID of each A element in the item container, which is composed of item plus an increasing number sequence starting with 0, as shown above The purple part; 
3. In the loading event onload in the WEB page, initialize and enable the carousel function, for example: 
window.onload=function(){
itemPlayerApp.init(' containerID',3000,300,200);
itemPlayerApp.active();
}
