* Parses a string into an array of DOM nodes.
|
|
*
|
|
* 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.
|
|
*
|
|
* As of 3.0 the default behavior is changed.
|
|
*
|
|
* If the context is not specified or given as null or undefined, a new document is used.
|
|
* This can potentially improve security because inline events will not execute when the HTML is parsed. Once the parsed HTML
|
|
* is injected into a document it does execute, but this gives tools a chance to traverse the created DOM and remove anything
|
|
* deemed unsafe. This improvement does not apply to internal uses of jQuery.parseHTML as they usually pass in the current
|
|
* document. Therefore, a statement like $( "#log" ).append( $( htmlString ) ) is still subject to the injection of malicious code.
|
|
*
|
|
* without context do not execute script
|
|
* $.parseHTML('<div><img src=1 onerror=alert(1)></div>');
|
|
* $.parseHTML('<div><img src=1 onerror=alert(2)></div>', null);
|
|
*
|
|
* with context document execute script!
|
|
* $.parseHTML('<div><img src=1 onerror=alert(3)></div>', document);
|
|
*
|
|
* 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.
|
|
*
|
|
* will return []
|
