javascript 部分代码
var pas = 0 ;
var premier = 0 ;
var lth = document.querySelectorAll('#tobj img').length;
window.addEventListener('touchstart',function(e){
e.preventDefault();
first = e.touches[0].pageX;
})
window.addEventListener('touchmove',function(e){
e.preventDefault();
var x = e.pageX || e.touches[0].pageX;
document.getElementById(' outs').innerHTML = step;
if(Math.abs(x - first)>10){
document.querySelectorAll('#tobj img')[step].style.display = 'none'
if(xétape ;
if(étape>=lth-1){
étape =0
}
}else{
étape--
if(step<=0){
step = lth-1;
}
}
first = x
document.querySelectorAll('#tobj img')[step ].style.display = 'block'
}
})
window.addEventListener('touchend',function(e){
e.preventDefault();
step = step;
})
核心精简

document.querySelectorAll('#tobj img')[step].style.display = 'none'
if(x< premier){

step =0
}
}else{
