Get content of the form into JS code

<script>
	var form = '[[ddGetChunk? &name=`someForm` &escapeResultForJS=`1`]]';
	
	//Insert form to page
	$('body').append(form);
</script>

Get chunk with Ditto and send necessary additional data into it

[[ddGetChunk?
	&name=`someChunk`
	&placeholders=`{
		id: 33
		orderBy: "someTv ASC, pub_date DESC"
	}`
]]

Code of someChunk:

<div class="some">
	<div class="someDesignDiv"></div>
	<div>
		[[Ditto?
			&startID=`[+id+]`
			&orderBy=`[+orderBy+]`
			&tpl=`someChunk_item`
		]]
	</div>
</div>

Run the snippet through \DDTools\Snippet::runSnippet without DB and eval

\DDTools\Snippet::runSnippet([
	'name' => 'ddGetChunk',
	'params' => [
		'name' => 'someChunk'
	]
]);
