Use this to dynamically create and set the content of a Bootstrap 4 Modal.

In this example, we chose an onclick handler to initialize the modal (only once), and then set the content of the modal dynamically.

A big thanks goes out to Sandeep Panda and his blog showing how to build an autocomplete for an Angular JS application.

	// Load the node and wrap it.
	$node = node_load(123);
	$wrap = entity_metadata_wrapper('node', $node);

	// Make sure the body isn't empty, and then sanitize it.
	// We use field_get_items() because we couldn't figure out how to use EMW's __isset() on the body field.
	$body = field_get_items('node', $node, 'body') ?
	$wrap->body->value->value(array('sanitize' => TRUE)) : '';
