类型错误：“未定义”不是（评估“ime.registIMEKey（）”）的函数

Question

尽管设置和三星智能电视SDK 4.0定义的一切我得到这个错误：

TypeError: 'undefined' is not a function (evaluating 'ime.registIMEKey()') 

请帮帮忙！

Answer 1

widgetAPI不包含方法registIMEKey（）;它包含在IMEShell中。

Answer 2

registIMEKey方法是Plugin API的一部分。

var pluginAPI = new Common.API.Plugin(); 
pluginAPI.registIMEKey();
