私はそのトピックの他のスレッドを熟読しましたが、それでも私のコードは動作するようにして助けを求めることができません。ここで JSからJavaメソッドを実行することができません
はコードです：BrowserComponent bc = new BrowserComponent();
bc.setDebugMode(true);
bc.setPage("<html><body></body></html>", null);
JavascriptContext context = new JavascriptContext(bc);
bc.addWebEventListener("onLoad", e -> {
{
JSObject syso = (JSObject) context.get("{}");
syso.set("print", new JSFunction() {
@Override
public void apply(JSObject self, Object[] args) {
System.out.println(StringUtils.injectArgs("{0} {1} {2} {3} {4} {5} {6} {7} {8} {9}", args));
}
});
context.set("window.syso", syso);
}
{
JSObject syso = (JSObject) context.get("syso");
syso.call("print", "I", "am", "in", "syso");
}
});
そして、ここでエラーです：
Error trying to execute js if (typeof(ca_weblite_codename1_js_JavascriptContext_LOOKUP_TABLE1) == 'undefined'){ca_weblite_codename1_js_JavascriptContext_LOOKUP_TABLE1=[]};(ca_weblite_codename1_js_JavascriptContext_RETURN_VAR_call_3=(ca_weblite_codename1_js_JavascriptContext_LOOKUP_TABLE1[0]).call(ca_weblite_codename1_js_JavascriptContext_LOOKUP_TABLE1[1], 'print', 'I', 'am', 'in', 'syso'))

私が間違っているのは何？
ご協力いただきありがとうございます。
スティーブがそれに答える資格があるかもしれませんが、この段階で 'syso'が定義されていないように見えます。 –
