路径算法函数最新修正版1.1

function GetPoint(obj,_jpx,_jpy)
{
var _w=obj.style.pixelWidth;
var _h=obj.style.pixelHeight;
var _left=obj.style.pixelLeft;
var _top=obj.style.pixelTop;

var _epx=(arguments.length<5)?event.x:arguments[3];
var _epy=(arguments.length<5)?event.y:arguments[4];
var _ajpx=((_jpx>_epx)?_epx:_jpx);
var _ajpy=((_ajpx==_epx)?_epy:_jpy);

  var _scale = (_aepx-_ajpx)/(_aepy-_ajpy);
  var _x=(_aepx-(_aepy-_tspy)*_scale).formatNumber(5);
  var _y=(_aepy-(_aepx-_tspx)/_scale).formatNumber(5);
  if(_y<_top||_y>(_top+_h))_y=_tspy;
  if(_x<_left||_x>(_left+_w))_x=_tspx;
}
return ([_x,_y]);
}

GetPoint(obj,_jpx,_jpy)
目标容器 obj (必选)
起点坐标 _jpx,_jpy (必选)
终点坐标 _epx,_epy (可选)

返回值为交点坐标数组[_x,_y]

工作流定义路径算法搞定了

路径算法终于搞定了汗啊~~
var _w=div2.style.pixelWidth;   //目标容器宽度
var _h=div2.style.pixelHeight;   //目标容器高度
var x0=div2.style.pixelLeft;   //容器左坐标
var y0=div2.style.pixelTop;   //容器上坐标
var _x=x0+_w/2;     //容器中心x轴坐标
var _y=y0+_h/2;     //容器中心y轴坐标
var x1=event.x;     //终点x轴坐标
var y1=event.y;     //终点y轴坐标
var x2=((xx>x1)?x1:xx);    //计算起点x轴坐标
var y2=((x2==x1)?y1:yy);   //计算起点y轴坐标
var x3=((xx<x0)?x0:((xx>x0+_w)?x0+_w:xx)); //交点终点x轴坐标
var y3=((yy<y0)?y0:((yy>y0+_h)?y0+_h:yy)); //交点终点y轴坐标
var x4=((xx>x1)?xx:x1);    //计算终点x轴坐标
var y4=((x4==xx)?yy:y1);   //计算终点y轴坐标
b=(x4-x2)/(y4-y2);
x5=(x4-(y4-y3)*b).format(0);
y5=(y4-(x4-x3)/b).format(0);
if(y5<y0||y5>(y0+_h))y5=y3;
if(x5<x0||x5>(x0+_w))x5=x3;
//交点坐标即为(x5,y5)
