我想我可能有一个合理的解决方案，不用计算div和像素..哈哈

简单地使用动画帧或一个时间间隔的函数。你仍然需要一个鼠标事件一次，虽然只是启动，但技术上你可以把它放在任何你喜欢的地方。

从本质上讲，我们一直在跟踪一个虚拟div，没有鼠标移动。

// create a div(#mydiv) 1px by 1px set opacity to 0 & position:absolute;

下面是逻辑。

var x,y;


$('body').mousemove(function( e ) {

    var x = e.clientX - (window.innerWidth / 2);
    var y = e.clientY - (window.innerHeight / 2);
 }


function looping (){

   /* track my div position 60 x 60 seconds!
      with out the mouse after initiation you can still track the dummy div.x & y
      mouse doesn't need to move.*/

   $('#mydiv').x = x;    // css transform x and y to follow 
   $('#mydiv)'.y = y;

   console.log(#mydiv.x etc)

   requestAnimationFrame( looping , frame speed here);
}  

这是我的解决方案。它导出窗口。currentMouseX和window。你可以在任何地方使用currentMouseY属性。它首先使用悬停元素的位置(如果有的话)，然后监听鼠标移动来设置正确的值。

(function () {
    window.currentMouseX = 0;
    window.currentMouseY = 0;

    // Guess the initial mouse position approximately if possible:
    var hoveredElement = document.querySelectorAll(':hover');
    hoveredElement = hoveredElement[hoveredElement.length - 1]; // Get the most specific hovered element

    if (hoveredElement != null) {
        var rect = hoveredElement.getBoundingClientRect();
        // Set the values from hovered element's position
        window.currentMouseX = window.scrollX + rect.x;
        window.currentMouseY = window.scrollY + rect.y;
    }

    // Listen for mouse movements to set the correct values
    window.addEventListener('mousemove', function (e) {
        window.currentMouseX = e.pageX;
        window.currentMouseY = e.pageY;
    }, /*useCapture=*/true);
}())

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。

是的，这是可能的。

如果你在文档中添加"mouseover"事件，它会立即触发，你可以得到鼠标的位置，当然，如果鼠标指针在文档上。

   document.addEventListener('mouseover', setInitialMousePos, false);

   function setInitialMousePos( event ) {
       console.log( event.clientX, event.clientY);
       document.removeEventListener('mouseover', setInitialMousePos, false);
   }

以前可以通过窗口读取鼠标位置。事件，但现在已弃用。

我设想，也许您有一个带有计时器的父页面，在一定时间或任务完成后，您将用户转发到一个新页面。现在你想要光标的位置，因为它们在等待，所以它们不一定会碰到鼠标。因此，使用标准事件跟踪父页面上的鼠标，并通过get或post变量将最后一个值传递给新页面。

你可以在你的父页上使用JHarding的代码，这样最新的位置总是在全局变量中可用:

var cursorX;
var cursorY;
document.onmousemove = function(e){
    cursorX = e.pageX;
    cursorY = e.pageY;
}

这将无法帮助通过父页面以外的方式导航到此页面的用户。

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));
