jQuery中如何完美解决Chrome下的mousemove事件bug？

var body = document.querySelector("h1");
var timeStamp;

body.addEventListener("mousedown", function (e) {
    console.log("mouse down");
}, false);

body.addEventListener("mouseup", function (e) {
    console.log("mouse up");
    timeStamp = e.timeStamp;
})

body.addEventListener("mousemove", function (e) {
    if (!timeStamp || ( e.timeStamp - timeStamp > 10)) {
        console.log("mouse move");    
    }
})

<input type="text" id="a1" />

$("#a1").mousemove(function(){
	if ($(this).data("x") === event.pageX && $(this).data("y") === event.pageY) {
		return false;
	}
	$(this).data({"x":event.pageX, "y":event.pageY});
	$(this).after("1");
})

document.onmousemove = function(e) {　　
// 不是move操作　　if (x === mouseDown.x && y === mouseDown.y) {
        return false;
    }};
document.onmousedown = function (e) {　　
mouseDown = { x: e.clientX, y: e.clientY };};
