所述键值扩展方法可应用在电视机上，电视机上安装的浏览器为嵌入式浏览器。电视机上的浏览器在启动时，需要加载各种文件，其中包括存储平台原始按键值及其对应的网页定义按键值的文件，如keymap.ini文件，还包括注入文件，如key_inject.js文件，注入文件包含的内容是需要注入的各个键值定义。
在本实施例中，所述指定的加载文件指keymap.ini文件和key_inject.js文件。电视机根据keymap.ini文件中的内容初始化得到所述哈希映射表，并将key_inject.js文件中的内容存储到电视机上。其中，所述哈希映射表包括键值及其映射值，即各个平台原始按键值及其映射的网页定义按键值。
S20、在打开一个网页时，根据存储的键值定义和所述网页已有的键值定义，将存储的键值定义中所述网页没有的键值定义注入到所述网页；
当在浏览器上打开一个网页时，电视机根据加载的网页信息获取到所述网页已有的键值定义，通过将所述网页已有的键值定义与所述存储的键值定义进行比较，从而确定出存储的键值定义中所述网页所没有的键值定义，此时，电视机将存储的键值定义中所述网页没有的键值定义注入到所述网页，使得所述网页增加了一些其所没有定义的键值定义，如键值定义var KEYUP=310表示网页中按键KEYUP对应的键值是310。
S30、在接收到所述网页上的按键请求时，根据所述按键请求包含的键值查询所述哈希映射表中所述网页需要的映射值，并将查询到的映射值返回给所述网页。
当电视机接收到一个平台（如遥控器或键盘）发送的在所述网页上的按键请求时，电视机根据所述按键请求中包含的键值（即平台原始按键值），从所述哈希映射表中查询所述键值对应的映射值（即网页定义按键值），并确定一个所述网页需要的映射值返回给所述网页，以使所述网页根据获得的按键映射值对平台上的按键事件作出响应。
本发明提出的键值扩展方法，在浏览器启动时，根据指定的加载文件初始化哈希映射表并存储需要注入的键值定义，在打开一个网页时，根据存储的键值定义和所述网页已有的键值定义，将存储的键值定义中所述网页没有的键值定义注入到所述网页，在接收到所述网页上的按键请求时，根据所述按键请求包含的键值查询所述哈希映射表中所述网页需要的映射值，并将查询到的映射值返回给所述网页，使得不同的网页虽然定义的同一按键的键值不同，但仍能在不修改浏览器内核配置的情况下得到网页支持的键值，从而正确地响应所述按键请求，提高了浏览器键值在不同网页上的兼容性，避免了修改浏览器内核配置导致存在很多版本的浏览器库的问题。
进一步地，基于第一实施例提出本发明键值扩展方法第二实施例，在本实施例中，参照图2，上述步骤S30包括：
S31、查询所述哈希映射表中是否存在所述键值；
其中，所述键值指的是所述按键请求中包含的平台原始按键值。
S32、当所述哈希映射表中存在所述键值时，判断所述键值的映射值中是否存在所述网页定义的映射值；
同一按键的平台原始按键值是相同的，而对于不同的网页，同一平台原始按键值对应不同的网页可映射有不同的网页定义按键值，即在所述哈希映射表中，所述键值可存在多个映射值，这些映射值分别对应不同的网页定义的同一按键的网页定义按键值。
电视机通过所述网页的网页信息能够获取到所述网页定义的所述键值对应按键的网页定义按键值，然后从所述哈希映射表中查找所述键值的映射值中是否存在所述网页定义按键值，从而判断所述键值的映射值中是否存在所述网页定义的映射值。
S33、当所述键值的映射值中存在所述网页定义的映射值时，将所述网页定义的映射值返回给所述网页。
当所述键值的映射值中存在所述网页定义的映射值时，表示电视机能够将所述按键请求中包含的平台原始按键值，对应转换为所述网页定义的网页定义按键值。在电视机将所述网页定义的映射值返回给所述网页后，所述网页能够根据返回的映射值对所述按键请求作出正确的响应。从电视机接收按键请求到网页作出响应的整个过程，电视机无需修改浏览器内核配置以使所述网页支持对所述按键请求的正确响应。
进一步地，上述步骤S30还包括：
S34、当所述键值的映射值中不存在所述网页定义的映射值时，将所述键值的默认映射值返回给所述网页。
当所述键值的映射值中不存在所述网页定义的映射值时，表示电视机根据所述按键请求中包含的平台原始按键值，无法将其转换为所述网页定义的网页定义按键值，此时，电视机将浏览器内核配置中，关于所述按键请求包含的平台原始按键值对应的网页的默认映射值，作为所述网页对所述按键请求的需求键值返回给所述网页，在所述网页采用与浏览器一致的按键定义标准时，即可根据返回的默认映射值对所述按键请求作出正确的响应。
本发明提出的键值扩展方法，对于网页定义的网页定义按键值在所述哈希映射表中存在时，便将与网页定义的网页定义按键值相同的映射值返回给网页，对于网页定义的网页定义按键值不存在所述哈希映射表的情况，便将浏览器内核配置的映射值返回给网页，以达到最大程度地正确返回网页支持的键值，从而使网页对按键请求作出正确的响应。
进一步地，基于第二实施例提出本发明键值扩展方法第三实施例，在本实施例中，参照图3，上述步骤S20包括：
S21、判断存储的各个键值定义是否存在于所述网页已有的键值定义中；
S22、将存储的各个键值定义中不存在于所述网页已有的键值定义中的键值定义，注入到所述网页。
电视机将存储的各个键值定义分别与所述网页已有的键值定义进行比较，从而判断得出存储的各个键值定义中不存在于所述网页已有的键值定义中的键值定义，然后将判断得出的这些键值定义注入到所述网页，以增强网页支持的不同键值定义的按键。
本发明提出的键值扩展方法，将浏览器存储的键值定义中网页没有的键值定义注入到网页中，增强了网页对不同按键的支持。
进一步地，基于第三实施例提出本发明键值扩展方法第四实施例，在本实施例中，参照图4，上述步骤S10包括：
S11、将加载的用于初始化哈希映射表的第一配置文件中的键值及其映射值保存到所述哈希映射表中；
S12、将加载的用于定义浏览器的各个键值的键值定义的第二配置文件保存到浏览器的内存中。
所述第一配置文件是指包括平台原始按键值及其对应的网页定义按键值的文件，如上述keymap.ini文件；所述第二配置文件是指包含需要注入的各个键值定义的文件，如上述key_inject.js文件。
当一个网页需要使用的按键是浏览器内核不支持的按键时，假设该网页对这样的一个按键KEYRED定义的网页定义按键值为408，按键KEYRED在平台上的平台原始按键值为110，则当电视机检测到该网页需要使用的按键KEYRED在浏览器上不支持时，电视机将按键KEYRED的平台原始按键值及其对应的该网页的网页定义按键值，对应添加到keymap.ini文件中，并将键值定义var KEYRED=408添加到key_inject.js文件中。
本发明提出的键值扩展方法，将网页需要的按键对应的网页定义按键值及键值定义分别添加到指定的加载文件中，以使浏览器启动时，获取到包含新添加的按键的哈希映射表和键值定义，从而使浏览器支持新添加的按键。
