Question

我在flash中制作了一个工作的AS3代码来显示和播放渐进式视频。我正在使用javascript动态地将其嵌入到具有指定宽度和高度的页面中。嵌入对象的高度和高度是正确的，但视频内容变得大于其容器的大小。那么当我将视频嵌入html中时，如何在AS3中调整视频大小以匹配它的容器对象？

AS3代码：

import flash.net.NetStream;
import flash.media.Video;
import flash.net.NetConnection;
import flash.events.MouseEvent;

var nc, ns, vd, st;
var isLoaded = false;
var isPlaying = false;
var vW = ExternalInterface.call('video.w');
var vH = ExternalInterface.call('video.h');

function video(w,h){
    nc = new NetConnection(); nc.connect(null);
    ns = new NetStream(nc);
    vd = new Video(w,h);

    ns.client = this;
    vd.attachNetStream(ns);
    stage.addChild(vd);
}

function playpause(e){
    if(isLoaded == false){
        ns.play('http://localhost.com/project/vid/sample_1.mp4');
        isLoaded = true;
        isPlaying = true;
    }
    else{
        if(isPlaying == false){
            ns.resume();
            isPlaying = true;
        }
        else{
            ns.pause();
            isPlaying = false;
        }
    }
}
video(vW,vH);
stage.addEventListener(MouseEvent.CLICK, playpause);

HTML：

<!DOCTYPE html>
<html>
    <head>
        <title>video</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <script>
            function player(container,w,h){
                var container = document.getElementById(container);
                var flashHTML = '<object type="application/x-shockwave-flash" data="video.swf" width="'+w+'" height="'+h+'"><param name="movie" value="video.swf" /><param name="quality" value="high" /><param name="bgcolor" value="#cccccc" /><param name="play" value="true" /><param name="loop" value="true" /><param name="wmode" value="window" /><param name="menu" value="true" /><param name="allowScriptAccess" value="sameDomain" /><a href="http://www.adobe.com/go/getflash"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></object>';

                container.innerHTML = flashHTML;

                this.w = function(){return w}
                this.h = function(){return h}
            }
        </script>
    </head>
    <body>
        <div id="flashContent"></div>
        <script>
            var video = new player('flashContent',853,480);
        </script>
    </body>
</html>

Answer 1

您需要将video.w和video.h称为函数，以便返回值。

var vW = ExternalInterface.call('video.w()');
var vH = ExternalInterface.call('video.h()');

应该有效
