Very simple JS switching effect (with extrapolate effect)

Today inadvertently found on the Internet, the code is very simple, a look at the JS image switching effect code, like simple friends can refer to.

Html:

1 <  src= "A1.jpg"  width= "478"  height= "286"  ID = "Showpic" />

The picture can be set by itself, let's take a look at the switch script, and use an array to load the picture together.

1 <Scripttype= "Text/javascript">2 window.onload= function(){    3     varCurindex= 0;4     varTimerInterval=  -; //time interval unit milliseconds5     vararr= NewArray ();6 arr[0] = "a1.jpg";7 arr[1] = "a2.jpg";8 arr[2] = "a3.jpg";9 arr[3] = "a4.jpg";Ten arr[4] = "a5.jpg"; One arr[5] = "a6.jpg"; A arr[6] = "a6.jpg"; - setinterval (changeimg,timerinterval); -     functionchangeimg () { the         varobj=document.getElementById ('Showpic'); -         if(Curindex==Arr.length- 1){ - Curindex= 0; -         }Else{ + Curindex+= 1; -         } + obj.src=Arr[curindex]; A     } at } - </Script>    

This piece of code is simple but ingenious.

After testing, automatic switching can be achieved completely.
