I don't think so unless you write a plugin to access the code in the DB. However you could easily create a hidden template IE ( _parsed_data.html). Then AJAX load it in to your to your current template using Jquery AJAX .load().
$("div#parsedData").load("{site_url}/templategroup/_parsed_data.html");
You can also with javascript depending on how you generate that url pass parameter restrictions through the url using segments.
Data Template:
{exp:channel:entries channel="news" limit="{segment_3}"}
<h2>{title}</h2>
{body}
{/exp:channel:entries}
Viewed Template:
var seg3 = 3;
$("div#parsedData").load("{site_url}/templategroup/_parsed_data.html/ '+ seg3");
