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(xstep ;
if(step>=lth-1){
step =0
}
}else{
step--
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;
})
