如何在GWTP中的AbstractPresenterModule中检索JavaScriptObject键/值？

我使用GWTP并希望在AbstractPresenterModule中使用Dictionary。我的静态主机页面包含以下JavaScriptObject：

var CurrentTheme = {
  highlightColor: "#FFFFFF",
  shadowColor: "#808080",
  errorColor: "#FF0000",
  errorIconSrc: "stopsign.gif"
};

和我的AbstractPresenterModule：

public class AppModule extends AbstractPresenterModule {

@Override
protected void configure() {

         Dictionary xx = Dictionary.getDictionary("Properties");



 }
}

这会引发以下错误：

如何从我的Module类访问JavaScriptObject？

1 个答案:

答案 0 :(得分：1)

来自杜松子酒的文档https://code.google.com/p/google-gin/wiki/GinFaq：

  

因为Module类实际上是在编译时执行的，所以你必须确保它的configure（...）方法不直接执行任何GWT客户端代码。

因此，您无法在Dictionary的{​​{1}}方法中使用configure。
