boxBack.onclick = function () {
let box = document.getElementById("box");
clearInterval(timeId_1);
timeId_2 = setInterval(function () {
if (box.offsetLeft <= 0) {
clearInterval(timeId_2);
box.style.left = "0";
alert('已在出发位置');
} else {
box.style.left = box.offsetLeft - 10 + 'px';
}
}, 100);
};
boxStop.onclick = function () {
clearInterval(timeId_1);
clearInterval(timeId_2);
};
