jQuery图像库中的上一个和下一个按钮

Question

I am making a simple image gallery

http://jsfiddle.net/QEh53/1/

Imgs array can store upto 36 images and i wants to display only first 6 onload. there is one next and back button, I need it when click on Next it will show next 6 images from Imgs array and on clicking Back last 6 images should slide in. if there is no img left in prev or next it should loop through next 6 images.

Thank you for any help.

Edit:

I have tried this with just back button but for some reason it is not removing old list before adding new one http://jsfiddle.net/QEh53/6/

Edit:

here was solution: jQuery gallery turn over with next and previous buttons

Answer 1

I belive this code will help you: example.js

total is the amount of "pages", you can set it as Math.ceil( totalImages / 6 ) .

This, nonstopping pages was called loop in that code. It returns a correct page, as you wanted.

function loop( value )
{
    return value < 0 ? total + value : ( value >= total ? value % total : value );
}
