我正在尝试读出对象的 x 和 y 位置。理想情况下，应该有一个“onclick”按钮，可以单击该按钮，然后读出并显示位置。这是代码和网站： https: //www.unisg.bplaced.net/JS/dragdrop3.html我想做的事情是读出位置并将其保存在变量中甚至在警报框中显示它们也会很棒。但是，我最终需要将它们保存在我的调查程序中。

只需指定 id 的属性之一dragMe，因为您已在上面的 css 中将位置指定为绝对位置，并在元素的内联 css 中将位置指定为相对位置。
并获取位置px添加代码为
<html><head>
<style>
#container {
width: 100%;
height: 400px;
background-image: url('http://www.unisg.bplaced.net/park2.png');
background-repeat: no-repeat;
background-size: contain;
display: flex;
align-items: center;
justify-content: center;
overflow: hidden;
border-radius: 7px;
touch-action: none;
}
#dragMe {
width: 100px;
height: 300px;
background-image: url('http://www.unisg.bplaced.net/silhoutte3.png');
background-size: 100px 300px;
background-repeat: no-repeat;
border-radius: 2em 2em 2em 2em;
position: absolute;
top: 10%;
left: 20%;
}
#dropMe {
width: 12em;
height: 12em;
padding: 0.5em;
margin: 0 auto;
}
</style>

$(document).ready(function(){

</script>
<button>Click me</button>
