我遇到了Bightcove(https://github.com/BrightcoveOS/Samsung-Smart-TV-Sample-App)为Samsung Smart TV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),并且是关于github的报告和在brightcove的支持论坛上。不幸的是,他们停止维护源代码,没有人回答这个问题。
在2010/2011模型上,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_keys
文件中的enginelite.platforms.js
对象:
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,
}
它可以在三星的所有平台上运行。

我建议检查生成的keymap,看看在init期间密钥处理程序中存储了哪些密钥:
for(key in $KEYS) {
alert(key+": "+$KEYS[key]);
this.keyMap[$KEYS[key]] = key;
}
然后捕获keydown事件中发送的密钥代码:
$(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;
});
这可以让您了解密钥处理程序中发生了什么。
