[Paraview] JavaScript API - ParaViewWeb - how to call function

[Tuan Ha Tran]

Thank you very much Seb,
I have another question : I read the simple.py and certainly, I found all the function about rendering, read file, etc. but I didn't find out anything about all the filters.
So if a want to use these filter, in python and after, in javascript. Where can I find the header (to know how to use these functions - some files like simple.py)? Do I have to import the vtk Library or something like that so we can use them in ParaViewWeb? 
About the plugin, I (suppose) write a plugin, with the .xml and .cxx file (as instructed in the Wiki page), write .py file and place it into the folder plugins of working-directory.
So, in the PWConsole, I suppose to load the plugin so it can be use in PWConsole? I wonder if i'm right.
Thank you once more.

For that you will need to know the name of the ParaView Proxy. You can
find-out by using ParaView and the trace function.
Then by referring to
http://www.paraview.org/Wiki/What_is_the_full_JavaScript_API , you
should be able to convert the Python trace to a JavaScript code.
Moreover, if you use directly the JavaScript console of Firebug or
Chrome, you have the completions on the ParaView object.

I think in your case you should write your code as follow:

p = paraview();
var reader = plugin.load('myFile.mhd');
filter = p.Threshold( {proxy:reader} ); // The arg is optional as the
reader is currently active
representation = p.Show()
p.Render()
