推薦：符合web標(biāo)準(zhǔn)的flash調(diào)用方法，解決了瀏覽器對(duì)flash的影響
最近在研究web標(biāo)準(zhǔn)，目前取得一些進(jìn)展，在制作過(guò)程中通過(guò)國(guó)外一些優(yōu)秀網(wǎng)站找到了解決flash調(diào)用符合標(biāo)準(zhǔn)的方法。首先建立一個(gè)js文件flash.js，內(nèi)容為：functio

看看效果吧：

AS如下：
//這個(gè)函數(shù)是用來(lái)繪制線條的
function connect(){
this.clear()
this.lineStyle(3,0x660000,100)
this.moveTo(anchorOne._x,anchorOne._y)
this.curveTo(controlOne._x,controlOne._y,anchorTwo._x,anchorTwo._y)
updateAfterEvent()
}
//這個(gè)函數(shù)是用來(lái)繪制替代描點(diǎn)跟控制點(diǎn)的MC，就繪制一個(gè)正方形吧
function createSquare(handle,side,offset){
if(offset==undefines){
offset=0
}
with(handle){
moveTo(offset,offset)
lineTo(offset,side)
lineTo(side,side)
lineTo(side,offset)
lineTo(offset,offset)
endFill()
}
}
//這是用來(lái)控制描點(diǎn)跟控制點(diǎn)的移動(dòng)，并且用延時(shí)，間隔一段時(shí)間調(diào)用一次繪制線條
function setDraggable(handle){
handle.onPress=function(){
clearInterval(_global.refreshScreen)
_global.refreshScreen=setInterval(this._parent,"connect",10)
this.startDrag(false)
}
handle.onRelease=function(){
clearInterval(_global.refreshScreen)
this.stopDrag()
}
handle.onReleaseOutside=function(){
clearInterval(_global.refreshScreen)
this.stopDrag()
}
}
//建立描點(diǎn)
anchorOne=createEmptyMovieClip("anchorPoint1",this.getNextHighestDepth())
anchorOne._x=anchorOne._y=50
//填充
anchorOne.beginFill(0xcccccc,100)
//樣式
anchorOne.lineStyle(0,0x000000,100,false,false,"none","miter",2)
//調(diào)用函數(shù)繪制成正方形
createSquare(anchorOne,8,-8)
//調(diào)用后方可拖動(dòng)
setDraggable(anchorOne)
//另一個(gè)描點(diǎn)
anchorTwo=createEmptyMovieClip("anchorPoint2",this.getNextHighestDepth())
anchorTwo._x=anchorTwo._y=250
anchorTwo.beginFill(0xcccccc,100)
anchorTwo.lineStyle(0,0x000000,100,false,false,"none","miter",2)
createSquare(anchorTwo,8,-8)
setDraggable(anchorTwo)
//控制點(diǎn)
controlOne=createEmptyMovieClip("control1",this.getNextHighestDepth())
controlOne._x=anchorTwo._x
controlOne._y=anchorOne._y
controlOne.beginFill(0xcccccc,100)
controlOne.lineStyle(0,0x000000,100,false,false,"none","miter",2)
createSquare(controlOne,8,-8)
setDraggable(controlOne)
//最后讓線條一開(kāi)始就顯示出來(lái)
connect()
復(fù)制粘貼就有效果。
