Issue regarding NativeArray assignment using Scriptable

[Shekhar Bhati <sh...@gmail.com>]

Hi All,

I have a serious problem using Rhino script.
I have a hidden input variable in my jsp and my task is to assign a array to
this object in a javascript file.
myform.myObject.value=myArray;

In my put(){} method I have written this code :

window.eval(name.toString() + '=' + value.toString());

It works for all other assignments other than this array one and gives this
array
*netscape.javascript.JSException: Failure to evaluate
value=NativeArray;@53537c*
Anyone have any idea how can I do this task.

Thanks & Regards,
Shekhar

Shekhar,

 

I think you have the wrong idea about this list.  This list is for
discussing issues related to the Batik SVG toolkit.  This is not a list for
discussing general JavaScript issues.  While Batik uses Rhino, you will not
find any help here in relation to general JavaScript problems.

 

You would have more luck in the comp.lang.javascript newsgroup.

 

Hope this helps,

 

John

As John says, this seems like a Rhino question more than a Batik
question.  However I can see from your output what the problem is: the
toString() of your NativeArray object doesn’t return a string that is
suitable for parsing again as script.  You’ll need to get something that
looks like "[1, 2, 3]".  Rhino implements a toSource() JavaScript method
on Array objects that will give you that.  Try this (untested):

  String jsSourceOfTheArray =
      ScriptableObject.callMethod(ctx, value, "toSource", null);

where ctx is your org.mozilla.javascript.Context object.
