html中SWF文件的高度和宽度

html中SWF文件的高度和宽度,html,actionscript-3,flash,mxmlc,Html,Actionscript 3,Flash,Mxmlc,在下面的代码中,只有按钮图像嵌入到flex代码中。但是在html对象或嵌入标记中,为什么必须指定高度和宽度。即使这是一个正常的按钮,如果我们不指定高度和宽度,似乎也有一些错误 html <div align="center"> <br /> <div style="display:block;width:100px;height:100px;" id="audio" class="testsound" align="center"/

嵌入标记中的高度和宽度是必需的属性。在标签定义上有一个gander,以及

您是否在问为什么需要它们,或者如果没有它们,为什么页面会断开(提示,第一个答案是第二个问题)

编辑:

您应该修改嵌入标记和对象标记的宽度和高度属性,使其与swf的大小完全一致

您可以在.mxml中设置应用程序的宽度和高度

<mx:Application width="300" height="200">
如果您使用的是ActionScript3(应该是),那么可以在主类中设置元数据

i、 e


除了@Dominic Tancredi的评论之外:
对象标记和嵌入标记都需要宽度和高度属性。

您应该在主mxml中指定
应用程序的宽度和高度,即使它只包含可单击的图像
如果您希望您的页面具有宽度为400px、高度为100px的flex图像(按钮??),则您的
应用程序标记必须如下所示:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" width="400" height="100">
其他 您的sndClass在哪里声明?如果已嵌入mp3,则脚本标记应包含:

<mx:Script>
    <![CDATA[
        import mx.core.SoundAsset; 

        [Embed('/media/players/music.mp3')]
        private var _sound:Class;
        public var snd:SoundAsset = new _sound() as SoundAsset;

        public var sndChannel:SoundChannel;

        public function playSound():void {
            sndChannel=snd.play();
        }   

    ]]>
</mx:Script>
请注意,最初该应用程序仅为1x1像素(如果小于1x1像素,则不会初始化!)
onCreationComplete
处理程序中,其大小将更改为与按钮大小匹配

这些值(宽度和高度)将传递给javascript函数
onFlashAppInited
,您还应更新该函数:

function onFlashAppInited(width, height) {
    alert("Flash app inited!");
    appInited = true;

    onFlashAppSizeChanged(width,height);

    // remove the temporary swf container: tmp
    document.body.removeChild(document.getElementById("tmp"));
}

function onFlashAppSizeChanged(width, height) {
    flashApp.width = width + "px";
    flashApp.height = height + "px";
}

但是现在从你的帖子来看,它并没有确切地建议应该做些什么来使swf适应html文件中的确切大小OK,在我上面的编辑中还有一些建议。希望这有帮助。我同意你在mxml和html中设置高度和宽度。但是默认情况下,我们不知道flex中按钮的大小,因此如果指定了默认按钮,如何知道其高度和宽度,以及如何在html中设置?:-?您可以尝试从flex中的onCreationComplete方法中检索按钮的大小(宽度/高度),并将其传递给javascript(作为参数沿flashAppInited方法传递)。通过这种方式,javascript端将收到关于按钮宽度的通知,并可以调整swf对象的大小,使其具有完全相同的大小。K..你能告诉我如何检索它的任何链接吗..顺便说一下,我看到了你的网站。虽然它不起作用,但已经很酷了..我已经更新了答案,基于此,您可以随时将flex按钮的大小发送到js端。也更新了样本(如果你想尝试的话)。目前为止运气好吗?如果您需要进一步指导,请告诉我+关于在flex和javascript之间使用通信的问题。
