本文实例讲述了JavaScript检测鼠标移动方向的方法。分享给大家供大家参考。具体实现方法如下：

function Start() { stage.addEventListener(MouseEvent.MOUSE_MOVE, CheckDirection); } Start(); var prevX=0; var prevY=0; var curX=0; var curY=0; var dirX:String=""; var dirY:String=""; function CheckDirection(e:MouseEvent) { trace("X movement: " + GetHorizontalDirection() + ", Y movement: " + GetVerticalDirection()); e.updateAfterEvent(); } function GetHorizontalDirection():String { prevX=curX; curX=stage.mouseX; if (prevX>curX) { dirX="left"; } else if (prevX < curX) { dirX="right"; } else { dirX="none"; } return dirX; } function GetVerticalDirection():String { prevY=curY; curY=stage.mouseY; if (prevY>curY) { dirY="up"; } else if (prevY < curY) { dirY="down"; } else { dirY="none"; } return dirY; }

希望本文所述对大家的javascript程序设计有所帮助。
