Filling text fields and clicking button on web page with Matlab

Solution for Filling text fields and clicking button on web page with Matlab
is Given Below:

Given the IDs of text fields and buttons of a geometry related web page (that is largely using Javascript; see URL below) I am searching for a step by step description in Matlab (R2016b) to fill some of the text fields with variable values and finally click on a (save-)button as part of a larger batch process.
I am aware of the Matlab RESTful web services functions (https://www.mathworks.com/help/matlab/internet-file-access.html) and HTTP Interface (https://www.mathworks.com/help/matlab/http-interface.html) but I do not know how to make my task with it.

The following IDs were determined with Firefox Inspector because a Matlab webread(URL) gets the html code but with the info that javascript is not enabled and no text field IDs could be identified this way in contrast to the button ID.

URL = 'http://geometricolor.ch/images/geometricolor/quadrilateral.html';

txt_field_ID_cell = {'DOM14', 'DOM19', 'DOM28', 'DOM37', 'circleSizetext', 'circlePositiontext'};

button_ID_cell = {'saveMapData'};

Before I am searching for CLI programs or scripts that can fill text fields and click buttons that I can call in Matlab with system() I would like to try it with Matlab R2016b alone if possible.
