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:
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;
} @H_502_5@
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;
} @H_502_5@
希望本文所述对大家的javascript程序设计有所帮助。
