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。

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);
});

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;
}

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));

不是鼠标位置，但是，如果你正在寻找当前光标位置(用例，如获取最后键入的字符等)，那么，下面的代码片段工作良好。 这将为您提供与文本内容相关的游标索引。

window.getSelection().getRangeAt(0).startOffset

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
