Re: How to use javascript to store variables to window correctly?

I'm not sure but... "return $wnd.key;" is the same as "return $wnd['key'];" which is not what you want, you should use "return $wnd[key];".

I am trying to use JSNI to set/get variable to/from js object:window like this:

private final native <T> T get(String key)/*-{      return $wnd.key;  }-*/;      private final native void set(String key, Object value)/*-{      $wnd.key = value;  }-*/;

and if I set a variable: var_1 to window:  (the definition of IdNameImpl is listed in the end)

IdName var_1=IdNameImpl.create("id_1","name_1");  set("key_1",var_1);

then

get("key_1")

I will get var_1 correctly

and then set another variable var_2 to window

IdName var_2=IdNameImpl.create("id_2","name_2");   set("key_2",var_2)

then,try to get key_1 again

get("key_1")

unexpectedly,var_2 will be returned

so,the problem is obvious:the get() method will always return the last set variable no matter what key is.Questions are:

1,Why?  2,How to make it right?

Blow is definition of IdNameImpl

public class IdNameImpl extends JavascriptObject implements IdName  {      public static final IdName create(String Id,String Name)/*-{          var o=new Object();            o.Id=Id;          o.Name=Name;            return o;      }-*/;        protected IdNameImpl()      {      }        @Override      public final native String getName()/*-{          return this.Name;      }-*/;          @Override      public final native void setName(String Name)/*-{          this.Name = Name;      }-*/;        @Override      public final native String getId()/*-{          return this.Id;      }-*/;          @Override      public final native void setId(String Id)/*-{          this.Id = Id;      }-*/;  }
