var x = 0;
var y = 0;

document.addEventListener('mousemove', onMouseMove, false)

function onMouseMove(e){
    x = e.clientX;
    y = e.clientY;
}

function getMouseX() {
    return x;
}

function getMouseY() {
    return y;
}

您不必移动鼠标来获得光标的位置。除了鼠标移动之外，位置也会在其他事件中报告。这里有一个点击事件的例子:

document.body.addEventListener('click',function(e)
{
    console.log("cursor-location: " + e.clientX + ',' + e.clientY);
});

真实的答案:不，这是不可能的。

OK, I have just thought of a way. Overlay your page with a div that covers the whole document. Inside that, create (say) 2,000 x 2,000 <a> elements (so that the :hover pseudo-class will work in IE 6, see), each 1 pixel in size. Create a CSS :hover rule for those <a> elements that changes a property (let's say font-family). In your load handler, cycle through each of the 4 million <a> elements, checking currentStyle / getComputedStyle() until you find the one with the hover font. Extrapolate back from this element to get the co-ordinates within the document.

N.b.，别这样。

重复@超新星的回答，这里有一个使用ES6类的方法，它在你的回调中保持正确的上下文:

class Mouse { constructor() { this.x = 0; this.y = 0; this.callbacks = { mouseenter: [], mousemove: [], }; } get xPos() { return this.x; } get yPos() { return this.y; } get position() { return `${this.x},${this.y}`; } addListener(type, callback) { document.addEventListener(type, this); // Pass `this` as the second arg to keep the context correct this.callbacks[type].push(callback); } // `handleEvent` is part of the browser's `EventListener` API. // https://developer.mozilla.org/en-US/docs/Web/API/EventListener/handleEvent handleEvent(event) { const isMousemove = event.type === 'mousemove'; const isMouseenter = event.type === 'mouseenter'; if (isMousemove || isMouseenter) { this.x = event.pageX; this.y = event.pageY; } this.callbacks[event.type].forEach((callback) => { callback(); }); } } const mouse = new Mouse(); mouse.addListener('mouseenter', () => console.log('mouseenter', mouse.position)); mouse.addListener('mousemove', () => console.log('mousemove A', mouse.position)); mouse.addListener('mousemove', () => console.log('mousemove B', mouse.position));

如果你渲染2000 x 2000 <a>个元素，@Tim Down的答案是不性能的:

但是你不需要一次呈现400万个元素，而是使用二分搜索。只需使用4 <a>元素即可:

第一步:考虑整个屏幕作为开始搜索区域 步骤2:将搜索区域分割成2 × 2 = 4个矩形<a>个元素 步骤3:使用getComputedStyle()函数确定鼠标悬停在哪个矩形中 步骤4:将搜索区域缩小到该矩形，并重复步骤2。

这样你将需要重复这些步骤最多11次，考虑到你的屏幕不超过2048px。

所以你将生成最多11 x 4 = 44 <a>个元素。

如果你不需要确定鼠标位置精确到一个像素，但说10px的精度是可以的。您将重复这些步骤最多8次，因此您将需要绘制最多8 x 4 = 32 <a>个元素。

生成并销毁<a>元素也不能执行，因为DOM通常很慢。相反，您可以重用初始的4 <a>元素，并在循环执行步骤时调整它们的顶部、左侧、宽度和高度。

现在，创建4 <a>也是多余的。相反，您可以在每个矩形中测试getComputedStyle()时重用相同的<a>元素。因此，不需要将搜索区域分割为2 × 2 <a>元素，只需要重复使用一个<a>元素，使用顶部和左侧样式属性移动它。

所以，所有你需要的是一个<a>元素改变它的宽度和高度最多11次，改变它的顶部和左侧最多44次，你就会有准确的鼠标位置。

最简单的解决方案，但不是100%准确

$(':hover').last().offset()

结果:{上:148，左:62.5} 结果取决于最近的元素大小，当用户切换选项卡时返回undefined
