An input field of type hidden, typically inserted into forms, the value taken from browser session storage.
Below is a Form1 widget, containing a TextInput2 widget, a HiddenSessionStorage widget and a SubmitButton2 widget. The HiddenSessionStorage widget has its key set to 'sessionone' so the contents of the storage dictionary at 'sessionone' will be sent to the server.
This table lists the Responders called to produce this page:
skiwidgets,10502 | SubmitData | Sets up the hiddensessionstorage page |
skiwidgets,10504 | This page | This page is a template for the inputforms.HiddenSessionStorage widget |
This is a ShowCallData widget, which displays the contents of the skicall.call_data dictionary.

Below is the Python file which populates this page.
