Question

我有两组代码。我的接收者和发送者应用程序。我对此还不陌生，它给了我很多问题。首先，最重要的是，我使用的是旧版chrome版本，这就是我的应用程序的运行方式。当我单击以投射给定的应用程序时，设备列表确实会下拉，但是当我单击以投射至设备时，我只能在连接到该铬合金投射器的电视上看到白屏，然后一分钟左右，该应用程序将停止投射并显示我出现“投放失败”错误消息。

从我的理解来看，index.html文件是我所有用于初始化API的js脚本的地方，并要求接收方代码上的会话是我具有以下所有代码的地方：

<div id="containerDiv" ></div>
    <div id="messageDiv"></div>
        <script type="text/javascript"
        src="//www.gstatic.com/cast/sdk/libs/receiver/2.0.0/cast_receiver.js"/>

    <script type="text/javascript">
        window.onload = function() {
            cast.receiver.logger.setLevelValue(0);
            window.castReceiverManager = cast.framework.CastReceiverContext.getInstance();
                console.log('Starting Receiver Manager');

            // handler for the 'ready' event
            castReceiverManager.onReady = function(event) {
                console.log('Received Ready event: '
                        + JSON.stringify(event.data));
                window.castReceiverManager
                        .setApplicationState("Application status is ready...");
            };

            // handler for 'senderconnected' event
            castReceiverManager.onSenderConnected = function(event) {
                console.log('Received Sender Connected event: ' + event.data);
                console
                        .log(window.castReceiverManager.getSender(event.data).userAgent);
            };

            // handler for 'senderdisconnected' event
            castReceiverManager.onSenderDisconnected = function(event) {
                console
                        .log('Received Sender Disconnected event: '
                                + event.data);
                if (window.castReceiverManager.getSenders().length == 0) {
                    window.open();
                }
            };

            // handler for 'systemvolumechanged' event
            castReceiverManager.onSystemVolumeChanged = function(event) {
                console.log('Received System Volume Changed event: '
                        + event.data['level'] + ' ' + event.data['muted']);
            };

            // create a CastMessageBus to handle messages for a custom namespace
            window.messageBus = window.castReceiverManager
                    .getCastMessageBus('urn:x-cast:com.theWebsite');

            // handler for the CastMessageBus message event
            window.messageBus.onMessage = function(event) {
                console.log('Message [' + event.senderId + ']: ' + event.data);

                // display the message from the sender
                displayText(event.data);
                // inform all senders on the CastMessageBus of the incoming message event
                // sender message listener will be invoked
                window.messageBus.send(event.senderId, event.data);
            }

            // initialize the CastReceiverManager with an application status message
            window.castReceiverManager.start({
                statusText : "Application is starting"
            });
            console.log('Receiver Manager started');
        };

        // utility function to display the text message in the input field
        function displayText(text) {
            console.log(text);
            panelSetup(text);
            //document.getElementById("messagePanelDiv").innerHTML = text;
            //$$('#messagePanelDiv').set('html', text);
            window.castReceiverManager.setApplicationState(text);
        };
    </script>
</body>

这里的问题是什么，因为我相信我的index.html页工作正常，因为我正在建立连接，否则当我单击按钮以投射文件时，将无法看到设备列表。但是连接并没有完全通过，这意味着它实际上从未连接。它说它已经连接，一分钟左右它说它没有连接。

基本上，我想知道是否检查接收方代码吗？还是只是我的索引文件没有正确初始化API？我还同时连接了新旧库，我认为新的libar会有所帮助，但不是这样

任何建议都有帮助。

单击“按钮”时会显示设备列表，但仅在选定的投射设备上显示白屏
