我正在尝试在我的网站上构建一个小游戏来试验JavaScript，它将热狗添加到碗中随机位置(构建一个金字塔形的堆然后覆盖页面(。
但我不确定如何实现它。 10个热狗应该进入碗里，然后还有50个应该洒到"游戏板"上，然后他们会随机覆盖网页。现在我只是想知道如果可能的话，如何仅使用 HTML、CSS 和 JavaScript 以随机方向onclick添加图像元素。代码如下所示：

欢迎，@drewemerine！
现在我只是想知道如果可能的话，如何仅使用 HTML、CSS 和 JavaScript 以随机方向添加图像元素。
我没有在HTML中有一个初始的热狗图像，而是创建了一个名为makeHotDog()的JavaScript函数来动态创建一个热狗图像。它利用了另一个函数，它只是吐出图像的随机坐标。我希望这对您有所帮助！
let food = 0;
let gameSpace = document.getElementById("gameSpace");
function getRandomPosition(element) {
let x = gameSpace.offsetHeight-element.clientHeight;
let y = gameSpace.offsetWidth-element.clientWidth;
let randomX = Math.floor(Math.random()*x);
let randomY = Math.floor(Math.random()*y);
return [randomX,randomY];
}
function makeHotDog() {
let img = document.createElement('img');
let xy = getRandomPosition(img);
img.setAttribute("src", "https://images.unsplash.com/photo-1515875976234-9d59c3ef288d?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=1050&q=80");
img.setAttribute("class", "hotdog");
gameSpace.appendChild(img);
img.style.top = xy[0] + 'px';
img.style.left = xy[1] + 'px';
}
function upDog() {
food++;
document.getElementById("gameScore").innerHTML = food;
makeHotDog();
}
gameSpace.onclick = upDog;body {
