判断鼠标是否在移动或静止状态

为window添加mousemove，移动时设置变量为true,静止后为false;

(function(){

    let isMove = false,

        timer = null;

    window.onmousemove = function(){

        isMove = true;

        clearTimeout(timer);

        console.log(isMove); // 移动时

        timer = setTimeout(function(){

            isMove = false;

            console.log(isMove); // 静止后

        },200);

    }

}());
