我遇到了 Bightcove (https://github.com/BrightcoveOS/Samsung-Smart-TV-Sample-App) 为三星智能电视提供的示例应用程序的问题。遥控器不适用于最新 (2012) 型号。这似乎是一个已知的错误（https://github.com/BrightcoveOS/Samsung-Smart-TV-Sample-App/issues/3），并且在 github 和 Brightcove 的支持论坛中被报告。不幸的是，他们停止维护源代码，没有人回复这个问题。

在 2010/2011 型号上一切正常。

我认为问题出在 enginelite.keyhandler.js 的某处：

/**
 * 
 *  Simple TV App Engine KeyHandler
 *  
 *  author: A Different Engine LLC.
 *  http://adifferentengine.com
 *  contact@adifferentengine.com
 *
 */
// This is pretty straightforward.
TVEngine.KeyHandler = {

    keyActions:  {
        KEY_UP:             'onUp',
        KEY_DOWN:           'onDown',
        KEY_LEFT:           'onLeft',
        KEY_RIGHT:          'onRight',
        KEY_ENTER:          'onSelect',
        KEY_RETURN:         'onReturn',
        KEY_STOP:           'onStop',
        KEY_FF:             'onFF',
        KEY_RW:             'onRew',
        KEY_PLAY:           'onPlay',
        KEY_PAUSE:          'onPause',
        KEY_YELLOW:         'onYellow',
        KEY_RED:            'onRed',
        KEY_BLUE:           'onBlue',
        KEY_GREEN:          'onGreen',
        KEY_EXIT:           'onExit',
        KEY_MENU:           'onMenu',
        KEY_BACK:           'onReturn',
        KEY_SKIPFFORWARD:   'onSkipForward',
        KEY_SKIPBACK:       'onSkipBack',
    },
    enabled: true,
    keyMap: {},

    init: function() {
        // Maps system key list to ours
        $KEYS = TVEngine.getPlatform().keys();
        // Transforming Samsung keymap into something we like slightly better.
        for(key in $KEYS) {
            this.keyMap[$KEYS[key]] = key;
        }
        this._initializeKeyHandler();
    },
    _cleared: true,
    _initializeKeyHandler: function() {
        var _this = this; var clear;
        $(document).bind("keydown", function(event) {
            var action = _this.keyActions[_this.keyMap[event.keyCode]];
            // $log("<<< GOT KEY ACTION: "+action+">>>");
            if ( action && _this.enabled ) _this.trigger("keyhandler:"+action);
            return false;
        });
        $(document).bind("keyup", function(event) {
            var action = _this.keyActions[_this.keyMap[event.keyCode]]+"Release";
            // $log("<<< GOT KEY ACTION: "+action+" >>>");
            if ( action ) _this.trigger("keyhandler:"+action);
            return false;
        })
    },

    enable: function(){
        this.enabled = true;
    },
    disable: function() {
        this.enabled = false;
    }
};
// Now we can subscribe to the keyhandler from anywhere. 
_.extend(TVEngine.KeyHandler, Backbone.Events);

有人能够解决这个问题吗？

干杯

您需要重写文件中的_keys对象enginelite.platforms.js：

this._keys = {
    KEY_RETURN:     88,     //36, //8
    KEY_UP:         29460,  //38,
    KEY_DOWN:       29461,  //40,
    KEY_LEFT:       4,      //37,
    KEY_RIGHT:      5,      //39,
    KEY_ENTER:      29443,  //13,
    KEY_RED:        108,    //65,
    KEY_GREEN:      20,     //66,
    KEY_YELLOW:     21,     //67,
    KEY_BLUE:       22,     //68,
    KEY_BACK:       8,      //I don't know what button on remote it is :)
    KEY_PLAY:       71,     //80,
}

它适用于所有三星的平台。

我建议检查生成的键映射以查看在初始化期间将哪些键存储在键处理程序中：

for(key in $KEYS) {
  alert(key+": "+$KEYS[key]);
  this.keyMap[$KEYS[key]] = key;
}

然后捕获 keydown 事件中发送的键码：

$(document).bind("keydown", function(event) {
  alert("keyCode: "+event.keyCode);
  alert("keyMap: "+_this.keyMap[event.keyCode]);
  var action = _this.keyActions[_this.keyMap[event.keyCode]];
  // $log("<<< GOT KEY ACTION: "+action+">>>");
  if ( action && _this.enabled ) _this.trigger("keyhandler:"+action);
  return false;
});

这应该让您了解 keyhandler 中发生了什么。
