js获取对象obj的坐标

function getElementPosition(element) {
    let x = 0;
    let y = 0;
    while (element) {
        x += (element.offsetLeft - element.scrollLeft + element.clientLeft);
        y += (element.offsetTop - element.scrollTop + element.clientTop);
        element = element.offsetParent;
    }
    return { x, y };
}

// 使用示例
const obj = document.getElementById('myElement');
const position = getElementPosition(obj);
console.log(`Element position: (${position.x}, ${position.y})`);

document.addEventListener('mousemove', function(event) {
    console.log(`Mouse position: (${event.clientX}, ${event.clientY})`);
});
