Question

尽管在三星智能电视SDK 4.0中设置并定义了所有内容，但我收到此错误：

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

请帮忙！

Answer 1

registIMEKey方法是Plugin API的一部分。

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

Answer 2

widgetAPI no包含方法registIMEKey（）;，它包含在IMEShell中。

TypeError：'undefined'不是函数（评估'ime.registIMEKey（）'）
