Hi Klaas,

BSFManager.eval (or BSFEngine.eval) should be the right method to use to
evaluate one or more JavaScript statements. Although the eval method takes
the name of a source as the first argument, the actual script statements are
passed as the last argument.

Although I haven't used eval to evaluate statements entered in a text field,
I've essentially been doing the equivalent operation by reading in the
contents of a file from disk, making it into a string, then passing the
string to the eval method as the last argument. I pass 0,0 as the line and
column numbers. The sequence looks something like this:

	BSFManager mgr = new BSFManager();
	mgr.eval( "javascript", scriptname == null ? "internal" :
scriptname, 0,0, statements );

Hi,

 I just read the infos at the bsf homepage. I downloaded the milestone build
and now try to set up my first application. At the moment I have a problem
evaluating a string. I instantiated an bsfmanger and used
loadScriptingEngine to get my javascript engine. What I need to to is to
evaluate a string that a user has written down in a textfield. I only found
one eval methode which seems not to be the one I am looking for. 

 

Can anybody help me? Maybe bsf is not the right thing to do the job.

 

BTW I didn't found the javadoc for the api. 

 

Thanks in advance,
