这是实验性技术
检查浏览器兼容性表格要小心谨慎在生产中使用这之前。

elementsFromPoint() 方法在 DocumentOrShadowRoot interface returns an array of all elements at the specified coordinates (relative to the viewport).

It operates in a similar way to the elementFromPoint() 方法。

句法

const elements = document.elementsFromPoint(x, y);

参数

x
y

返回值

An array of element 对象。

范例

HTML

<div>
  <p>Some text</p>
</div>
<p>Elements at point 30, 20:</p>
<div id="output"></div>

JavaScript

let output = document.getElementById("output");
if (document.elementsFromPoint) {
  let elements = document.elementsFromPoint(30, 20);
  for (var i = 0; i < elements.length; i++) {
    output.textContent += elements[i].localName;
    if (i < elements.length - 1) {
      output.textContent += " < ";
    }
  }
} else {
  output.innerHTML = "<span style=\"color: red;\">" +
     "Browser does not support <code>document.elementsFromPoint()</code>" +
     "</span>";
}
