This code primarily powers an interactive user interface for managing simulation recordings. Here's a breakdown of its functionality:
Overall Purpose:
The JavaScript code defines a web-based control panel or dashboard that interacts with an underlying service via REST APIs, leveraging the AnalogWebbRest
class (potentially a library or abstraction layer for REST operations). It centers around managing simulation recordings that can be in multiple states such as playing, paused, or stopped.
Key Functionalities:
-
Grid Setup for Displaying Recordings:
-
Uses SlickGrid to create a grid-based table UI for displaying recording data.
-
The table includes columns for:
- Delete (deletes a recording).
- Name (recording name).
- Play/Pause (toggles between playing and pausing).
- Stop (stops the simulation playback).
-
Clicking on grid cells triggers appropriate actions (
Delete
,Play/Pause
,Stop
) depending on the context.
-
-
Simulation Control Modes:
- Adds a dropdown
#controlModeType
and buttons for managing "control modes". - Modes are fetched dynamically from a service using the
AnalogWebbRest.getSimulationControlMode()
method. - Allows setting a new control mode via the dropdown and updates the state on the UI using
AnalogWebbRest.setSimulationControlMode()
.
- Adds a dropdown
-
Recording Management:
- Functions (
loadSimulationRecording
,deleteSimulationRecording
, etc.) define how to interact with an API to manage simulation recordings.- Upload recordings: Provides a file input (
#recordingFile
) for uploading new recording files. - Load recordings: Dynamically fetches existing simulations using APIs (e.g.,
getSimulationRecordings
,getLoadedSimulationRecordings
) and populates the grid. - Delete recordings: Deletes a recording through a REST API call.
- Upload recordings: Provides a file input (
- Supports playback functions such as:
- Playing, pausing, and stopping recordings.
- Loading or unloading recordings.
- Functions (
-
REST-based Interaction:
AnalogWebbRest
is used throughout to interact with simulation APIs for operations like fetching recordings, starting/stopping playback, and managing states.
-
Playback State Management:
- Periodically checks for the state of all recordings (e.g., whether they are playing) using
getSimulationRecordingPlaybackState()
. - Updates the grid in real-time to reflect changes in playback or other recording states.
- Periodically checks for the state of all recordings (e.g., whether they are playing) using
-
Responsive UI Updates:
- Redraws the grid or resizes it (
resizeCanvas
) in response to window resizing. - Listens for state changes in recordings (
onRowCountChanged
,onRowsChanged
) to keep the grid updated.
- Redraws the grid or resizes it (
-
Error Handling:
- Displays error messages using
alert
when API calls fail. - Provides feedback to the user when operations like file uploads or control mode setting fail.
- Displays error messages using
Key Components:
-
Functions and Handlers:
e()
: Updates the control mode dropdown and current mode.o()
: Fetches and initializes the list of simulation recordings.g()
: Updates the grid with "loaded" recordings.p()
: Handles user interactions (e.g., clicking play, stop, or delete in the grid).ft()
: Periodically checks playback states and updates the grid.
-
SlickGrid Setup:
- The grid (
#recordingsGrid
) manages recordings and their states through columns and custom formatters (e.g.,l()
,a()
,v()
).
- The grid (
-
UI Elements:
- Buttons and file inputs with specific IDs (
#setControlModeButton
,#uploadRecordingButton
, etc.) provide user interaction points.
- Buttons and file inputs with specific IDs (
-
Global Variables:
t
: The SlickGrid instance.n
: The DataView for the grid.r
: A dictionary for current recordings, keyed by name.f
: Timer for periodic state checks.
Execution Flow:
-
Upon page load (
$(function() {...})
):- Initializes the grid and associated handlers (
y()
). - Fetches the list of available recordings (
o()
) and control modes (e()
).
- Initializes the grid and associated handlers (
-
Handles user interactions:
- Clicking buttons or grid cells triggers playback actions (
p()
), file uploads, or control mode changes.
- Clicking buttons or grid cells triggers playback actions (
-
Periodically syncs playback states:
- Uses a timer (
ft()
) to check and update playback states for all recordings.
- Uses a timer (
-
Dynamically updates the UI:
- Refreshes the grid when recordings or states change.
Summary:
This code provides a robust client-side system for managing simulation recordings through a web interface, tightly integrating with backend REST APIs for real-time updates and playback management. These functionalities would suit scenarios like controlling playback systems in a simulation environment, interactive demos, or educational tools.
