Does jQuery have a JSON/Javascript object to HTML pretty print function similar to PHP's var_dump? If yes, what is it?

jQuery does not (out of the box).
However, James Padolsey created this prettyPrint which I really like.
Also, if you're using Firebug or Web Inspector (or similar), you can just type the object into the console, press return, and see a tree-dump of the object. To force a tree-view, call console.dir(obj)

Although the accepted answer is correct that jQuery does not have a pretty print feature for JSON, that feature is now included in out of the box javascript through JSON.stringify()'s space argument.
To print to HTML, wrapping the output with <pre> </pre> will preserve the line spacing for readability purposes.
var obj = {a:1, 'b':'foo', c:[false,'false',null, 'null', {d:{e:1.3e5,f:'1.3e5'}}]};
var str = "<pre>" + JSON.stringify(obj, undefined, 4) + "</pre>";
/* Returns
{
"a": 1,
"b": "foo",
"c": [
false,
"false",
null,
"null",
{
"d": {
"e": 130000,
"f": "1.3e5"
}
}
]
}

The question was to pretty print HTML, not to pretty print JSON.

I know this isn't the answer to the question but I like this rather than having to use some other dependency.
Using Jquery, you can have object.serialize() to output an object. This is similar to var_dump() in php or Zend_Debug::dump() in Zend.
