为什么我不能让 Javascript 与 ActionScript 对话
我有一个非常简单的 Flash 程序来播放音乐。它由一个播放暂停按钮和一个显示歌曲当前位置的计时器组成。我正在尝试使用常规表单按钮来暂停或播放歌曲。
<div class="musicplayer_playpause">
<script type="text/javascript">
AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','65','height','68','src','player','quality','high','pluginspage','http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','wmode','transparent','id','flashobject','movie','player','flashvars','id=<?=$cur_songid;?>&type=<?=$_GET["type"];?>&csid=<?=$cur_songid;?>&l=<?=$Arrcntt+1;?>"' ); //end AC code
</script><noscript><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0" id="flashobject" width="65" height="68">
<param name="movie" value="player.swf" allowscriptaccess="always"/>
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<param name="id" value="flashobject" />
<param name="swliveconnect" value="true" />
<embed src="player.swf" name="flashobject" width="65" height="68" quality="high" allowscriptaccess="always" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" wmode="transparent" swliveconnect="true" ></embed>
</object>
</noscript></div>
这是我放在以下部分中的 Javascript 函数:
<script type="text/javascript">
function Pause() {
var flash = document.getElementById('flashobject');
flash.PlayPause;
}
</script>
最后这是我正在使用的按钮:
<form>
<input type="button" value="Play" name="Play" onClick="Pause();">
</form>
当我单击该按钮时,Firefox 的错误控制台显示“Flash 为空” 我做错了什么?
I have a very simple flash program that plays music. It consists of a play pause button and a timer that shows the current position of the song. I'm trying to make it possible to pause or play the song using a regular form button.
<div class="musicplayer_playpause">
<script type="text/javascript">
AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','65','height','68','src','player','quality','high','pluginspage','http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','wmode','transparent','id','flashobject','movie','player','flashvars','id=<?=$cur_songid;?>&type=<?=$_GET["type"];?>&csid=<?=$cur_songid;?>&l=<?=$Arrcntt+1;?>"' ); //end AC code

<param name="movie" value="player.swf" allowscriptaccess="always"/>
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<param name="id" value="flashobject" />
<param name="swliveconnect" value="true" />
<embed src="player.swf" name="flashobject" width="65" height="68" quality="high" allowscriptaccess="always" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" wmode="transparent" swliveconnect="true" ></embed>
</object>
</noscript></div>
Here's the Javascript function, which I put in the section:
<script type="text/javascript">
function Pause() {
var flash = document.getElementById('flashobject');
flash.PlayPause;
}
</script>
And finally here's the button I'm using:
<form>
<input type="button" value="Play" name="Play" onClick="Pause();">
</form>
When I click the button, Firefox's error console says "Flash is null" What am I doing wrong?

我不认为这可以直接解决您的问题,但我从经验中知道,使用
不会在所有流行的浏览器中显示相同的行为。您可以尝试使用以下函数返回对象:
但是,如果您使用的是 jQuery,则可以执行以下操作:
编辑:我找到了 thisMovie 函数的更新版本。不过我仍然推荐 jQuery 方式:)
I don't think it's a direct solution to your problem, but I know from experience that using
will not show the same behaviour in all popular browsers. you can try to use the following function to return the object:
If you are using jQuery however, the following will do:
edit: I found a more updated version of the thisMovie function. I would still recommend the jQuery way though :)
包含 Pause 的脚本标记格式错误。向 type 属性添加尾部引号。
此外,AC_FL_RunContent 没有定义电影的 id。添加 4 个参数 - 'id'、'flashobject'、'name'、'flashobject'。
AC_FL_RunContent 在此 Adobe 技术说明 http://kb2.adobe.com/cps/127 中进行了描述/tn_12701.html,其中内容如下:
The script tag containing Pause is malformed. Add a trailing quote to the type attribute.
Additionally, AC_FL_RunContent is not defining an id for the movie. Add 4 more params to it - 'id', 'flashobject', 'name', 'flashobject'.
AC_FL_RunContent is described in this Adobe technote http://kb2.adobe.com/cps/127/tn_12701.html, which says this:
找到这个:
替换为
我仍然会使用 Jasper 的函数
find this:
<param name="movie" value="player.swf" allowscriptaccess="always"/>
replace with
I would still use Jasper's function
Jasper 具有正确的 JavaScript 方法,但您还需要 在 ActionScript 中为 JS 函数添加回调,以便 AS 知道监听它们。
AS代码:
Jasper has the right JavaScript method, but you also need to add callbacks for your JS functions in ActionScript, so that AS knows to listen for them.
