How to pass in a struct to javascript

Sorry I made a mistake in my code.
Replace with:

Code:

chrome.runtime.sendMessage(editorExtensionId, <?php echo '"'.$command.'"'; ?>,

Don't use jsonencode in your controller

The thing is that I  need to send more than just the 'command' string. I have the struct named $data which has both a "command" string and a "message" string.  So that is why I tried $data.
