Add custom Buttons and Scripts to JDownloader

The Eventscripter can be used to write Scripts in JavaScript to customize your JDownloader.
Install- and activate the Eventscripter in the JDownloader Settings panel.

Adding Buttons that execute scripts when clicked

You can add buttons to almost all menus in JDownloader. Open the Menu Manager (Settings->User Interface->Menu Manager) and add a "EventScripter Trigger" Button.

For this example we are going to use a toolbar button.

Alternatively right click anywhere in the free space in the main menu -> Open menu toolbar 

Choose a name for the action (1).
This step is important, because we will need this name later in the scripts.
For this example, we choose the name -> "EventScripter Trigger"
Moreover, you can choose an icon (2) and a shortcut (3) for the action.

Click Save and the Button will appear in your menu.

Switch to the EventScripter and create a new Script (Click Add)

1. Switch to the EventScripter -> Click on "Add" to add a custom script.
2. Enable the Script.
3. Choose a Name (Whatever you want).
4. Choose the Trigger.
   We added as button to the Toolbar, so we choose the Toolbar Button Pressed Trigger. 
5. Click the Edit Button

The Help Panel contains a documentation about the EventScripter API.
If you miss anything for your script, just ask our support.

1. Write a simple Script that shows an alert box.
   To be sure that this script only is executed for the button we created, and not for other custom buttons in the same menu, we add the if (name == "EventScripter Trigger") { ... } statement.
   Here is the code for such a simple test-script:
   if (name == "Toolbar Button Pressed"){
    alert("My Button pressed");
}
2. Use the auto format button to format your script in a clean way.
3. Use the Test Compile Button to check if you Script Syntax is correct.
4. Click [Save] to save your script and exit the editor.

Click your button and a dialog box will appear.

Troubleshooting:

If nothing happens, check that:

• your script is enabled
• if the script should only work for a specifically named b utton, the name of your button and the name your scriupt is checking for match. In this example it's Toolbar Button Pressed .

All scripts disable themselves if there are any errors in the script. If this happens, check your script, re-enable it and troubleshoot it until it doesn't throw an exception anymore.
