js 判断鼠标不动

let lastMousePosition = { x: 0, y: 0 };
let lastMouseMoveTime = Date.now();
const inactivityThreshold = 2000; // 2秒

// 监听鼠标移动事件
document.addEventListener('mousemove', (event) => {
    lastMousePosition = { x: event.clientX, y: event.clientY };
    lastMouseMoveTime = Date.now();
});

// 定期检查鼠标是否不动
setInterval(() => {
    const currentTime = Date.now();
    if (currentTime - lastMouseMoveTime > inactivityThreshold &&
        lastMousePosition.x === getLastRecordedPosition().x &&
        lastMousePosition.y === getLastRecordedPosition().y) {
        console.log('鼠标不动');
        // 这里可以执行其他操作，比如显示提示信息等
    }
}, 1000); // 每秒检查一次

// 辅助函数，用于获取上一次记录的鼠标位置
function getLastRecordedPosition() {
    return lastMousePosition;
}
