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;
}-*/;}
