Jquery

យើងបន្ថែម jquery ដើម្បីឲ្យវាដើរម្តងមួយ

$(document).ready(function(){
    var slise = $(".slider")
    var num = 0
    var slideLength = slise.length 

    slise.hide()
    slise.eq(num).show()

    $(".nextBtn").click(function(){
        slise.eq(num).hide()//0
        num++ //0->1->2->3
        if(num === slideLength){// 0 == 3?
            num = 0
        }
        slise.eq(num).show()//1
    })

    $(".backBtn").click(function(){
        slise.eq(num).hide()
       num--
       if(num<0){
        num = slideLength-1 // 3-1 = 2 (2 is index 3th)
       }
       slise.eq(num).show()
    })
})
