jQuery.parseHTML uses native methods to convert the string to a set of DOM nodes, which can then be inserted into the document. These methods do render all trailing or leading text (even if that's just whitespace). To prevent trailing/leading whitespace from being converted to text nodes you can pass the HTML string through jQuery.trim.
By default, the context is the current document if not specified or given as null or undefined. If the HTML was to be used in another document such as an iframe, that frame's document could be used.
Security Considerations
Most jQuery APIs that accept HTML strings will run scripts that are included in the HTML. jQuery.parseHTML does not run scripts in the parsed HTML unless keepScripts is explicitly true. However, it is still possible in most environments to execute scripts indirectly, for example via the <img onerror> attribute. The caller should be aware of this and guard against it by cleaning or escaping any untrusted inputs from sources such as the URL or cookies. For future compatibility, callers should not depend on the ability to run any script content when keepScripts is unspecified or false.

Document element to serve as the context in which the HTML fragment will be created
A Boolean indicating whether to include scripts passed in the HTML string
Create an array of DOM nodes using an HTML string and insert it into a div.
