如何制作迷你游戏的计数器？

我想为我的迷你网络项目制作游戏，我遇到了这些代码来帮助我制作游戏，这个游戏的目的是将正确的图片与正确的位置相匹配（在这种情况下，North，中心，南）。我得到了验证工作，我想知道当最后一张图片放入正确的方框时是否可以创建一个提示框。另外我还有一个计时器，我想知道是否有可能在用户完成游戏时在提示上打印时间。我只允许使用HTML，CSS和JavaScript。 

//Timer//
var h1 = document.getElementsByTagName('h1')[0],
    start = document.getElementById('start'),
    stop = document.getElementById('stop'),
    clear = document.getElementById('clear'),
    seconds = 0, minutes = 0, hours = 0,
    t;

function add() {
    seconds++;
    if (seconds >= 60) {
        seconds = 0;
        minutes++;
        if (minutes >= 60) {
            minutes = 0;
            hours++;
        }
    }
    
    h1.textContent = (hours ? (hours > 9 ? hours : "0" + hours) : "00") + ":" + (minutes ? (minutes > 9 ? minutes : "0" + minutes) : "00") + ":" + (seconds > 9 ? seconds : "0" + seconds);

    timer();
}
function timer() {
    t = setTimeout(add, 1000);
}
timer();
//End of Timer//

//Start Game//
// add event handler
var addEvent = (function () {
  if (document.addEventListener) {
    return function (el, type, fn) {
      if (el && el.nodeName || el === window) {
        el.addEventListener(type, fn, false);
      } else if (el && el.length) {
        for (var i = 0; i < el.length; i++) {
          addEvent(el[i], type, fn);
        }
      }
    };
  } else {
    return function (el, type, fn) {
      if (el && el.nodeName || el === window) {
        el.attachEvent('on' + type, function () { return fn.call(el, window.event); });
      } else if (el && el.length) {
        for (var i = 0; i < el.length; i++) {
          addEvent(el[i], type, fn);
        }
      }
    };
  }
})();



// inner variables
var dragItems;
updateDataTransfer();
var dropAreas = document.querySelectorAll('[droppable=true]');

// preventDefault (stops the browser from redirecting off to the text)
function cancel(e) {
  if (e.preventDefault) {
    e.preventDefault();
  }
  return false;
}

// update event handlers
function updateDataTransfer() {
    dragItems = document.querySelectorAll('[draggable=true]');
    for (var i = 0; i < dragItems.length; i++) {
        addEvent(dragItems[i], 'dragstart', function (event) {
            event.dataTransfer.setData('obj_id', this.id);
            return false;
        });
    }
}

// dragover event handler
addEvent(dropAreas, 'dragover', function (event) {
    if (event.preventDefault) event.preventDefault();

    // little customization
    this.style.borderColor = "#fff";
    return false;
});

// dragleave event handler
addEvent(dropAreas, 'dragleave', function (event) {
    if (event.preventDefault) event.preventDefault();

    // little customization
    this.style.borderColor = "#ccc";
    return false;
});

// dragenter event handler
addEvent(dropAreas, 'dragenter', cancel);

// drop event handler
addEvent(dropAreas, 'drop', function (event) {
    if (event.preventDefault) event.preventDefault();

    // get dropped object
    var iObj = event.dataTransfer.getData('obj_id');
    var oldObj = document.getElementById(iObj);

	// validate the placement of the image
	if(this.id !== oldObj.dataset.dropTo) {
        return false;
    }
    // get its image src
    var oldSrc = oldObj.childNodes[0].src;
    oldObj.className += 'hidden';

    var oldThis = this;

    setTimeout(function() {
        oldObj.parentNode.removeChild(oldObj); // remove object from DOM

        // add similar object in another place
        oldThis.innerHTML += '<a id="'+iObj+'" draggable="true"><img src="'+oldSrc+'" /></a>';

        // and update event handlers
        updateDataTransfer();

        // little customization
        oldThis.style.borderColor = "#3e8bc6";
    }, 500);

    return false;
});

尝试更新以下部分：

// drop event handler
addEvent(dropAreas, 'drop', function (event) {
    if (event.preventDefault) event.preventDefault();

    // get dropped object
    var iObj = event.dataTransfer.getData('obj_id');
    var oldObj = document.getElementById(iObj);

    // validate the placement of the image
    if(this.id !== oldObj.dataset.dropTo) {
        return false;
    }
    // get its image src
    var oldSrc = oldObj.childNodes[0].src;
    oldObj.className += 'hidden';

    var oldThis = this;

    setTimeout(function() {
        oldObj.parentNode.removeChild(oldObj); // remove object from DOM

        // add similar object in another place
        oldThis.innerHTML += '<a id="'+iObj+'" draggable="true"><img src="'+oldSrc+'" /></a>';

        // and update event handlers
        updateDataTransfer();

        // little customization
        oldThis.style.borderColor = "#3e8bc6";

    if (document.querySelectorAll('.gallery > a').length < 1) {
        alert('Congratulations!\nTime elapsed:' + hours + ':' + minutes + ':' + seconds);
    }
    }, 500);
    return false;
});

在更换DOM元素后，我在drop事件中添加了以下代码以获取提示（自定义）。

if (document.querySelectorAll('.gallery > a').length < 1) {
        alert('Congratulations!\nTime elapsed:' + hours + ':' + minutes + ':' + seconds);
    }
