Thanks,followed your suggestion,changed to
|private final native <T> Tget(String key)/*-{
return $wnd[key];
}-*/;
private final native void set(String key, Object value)/*-{
$wnd[key] = value;
}-*/;|
It works now.

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> Tget(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;
}-*/;
