获取鼠标运动的轨迹

    以下代码是在网面上把鼠标运动的轨迹给记录下来：
使用了jquery相关的一些方法，鼠标事件等。

var gesture = {};
var total_point = 0;
var number_column = 3;
var number_row = 3;
var bounds_x = [];
var bounds_y = [];


function getTotalHeight(){ 
	if($.browser.msie){ 
		return document.compatMode == "CSS1Compat"? document.documentElement.clientHeight : document.body.clientHeight; 
	} 
	else { 
		return self.innerHeight; 
	} 
} 

function getTotalWidth (){ 
	if($.browser.msie){ 
		return document.compatMode == "CSS1Compat"? document.documentElement.clientWidth : document.body.clientWidth; 
	} 
	else{ 
		return self.innerWidth; 
	} 
} 


function get_pointer(e) { 
	var xx = e.originalEvent.x || e.originalEvent.layerX || 0; 
	var yy = e.originalEvent.y || e.originalEvent.layerY || 0; 
	var x_sequens="";
	for(var i=0;i<number_column-1;i++){
		if(xx>bounds_x[i]){
			x_sequens+="1";
		}else{
			x_sequens+="0";
		}
	}
	
	var y_sequens="";
	for(var i=0;i<number_row-1;i++){
		if(yy>bounds_y[i]){
			y_sequens+="1";
		}else{
			y_sequens+="0";
		}
	}
	//console.log(x_sequens+y_sequens);
	//判断序列结果是否为上一次相同，不相同就记录下来，相同不记录
	if(total_point==0 || gesture[total_point-1]!=x_sequens+y_sequens){
		//console.log("impossible");
		//console.log(gesture[total_point-1]);
		//console.log(x_sequens+y_sequens);
		gesture[total_point] = x_sequens+y_sequens;
		total_point++;
	}
	
	//console.log(total_point);
}

function get_pointer_start() {
	
	//全局变量初始化
	gesture = {};
	total_point = 0;
	bounds_x = [];
	bounds_y = [];
	
	//取得当前窗口的大小
	var do_width = getTotalWidth();
	var do_height = getTotalHeight();
	var unit_width=do_width/number_column;
	for(var i=0;i<number_column;i++){
		bounds_x[i] = (i+1)*unit_width;
	}
	var unit_height=do_height/number_row;
	for(var i=0;i<number_row;i++){
		bounds_y[i] = (i+1)*unit_height;
	}
	//采集数据
	$(document).mousemove(get_pointer);
}

$(document).mousedown(get_pointer_start);
$(document).mouseup(function(){
	$(this).unbind("mousemove",get_pointer);

	if(total_point<=3){
		
		return;
	}
	
	//计算最终结果
	var result="";
	for(var i=0;i<total_point;i++){
		if(i==0){
			result = gesture[i];
		}else{
			result = result+"-"+gesture[i];
		}
	}
        //输出结果
	console.log(result);
});
