Getting jQuery to work in Jetpack

Question

I am experimenting with Jetpack and I would like to parse all the years in a given html page and then wrap the year with a link to the Wiki page. I tried the code in jquery and there it works but now I am using it in Jetpack and it gives an error $(doc).replace is not a function. I am definitely new to Jquery / Jetpack so maybe I am missing something really easy but your help is much appreciated.

EDIT: I have tried the suggestions but I am still stuck. The weird thing is that this

JQuery function works:

(function($) {
    $.fn.clickUrl = function() {  
            var regexp = /([1-2][0-9][0-9][0-9])/gi;
            this.each(function() {
            $(this).html(
                  $(this).html().replace(regexp,'<ahref=\"http://nl.wikipedia.org/wiki/$1\">$1<\/a>')
            );
        });
    return $(this);
    }
})(jQuery);

and basically, I would like to 'port' this function to Jetpack.

This is the 'old' non-working port of my JQuery function to Jetpack:

jetpack.statusBar.append({  
    html: "Hyperlink Years",  
    width: 80,  
    onReady: function(widget){  
        $(widget).click(function(){  
        var regexp = /([1-2][0-9][0-9][0-9])/gi;
        var doc = jetpack.tabs.focused.contentDocument;
            $(doc).each(function() {
            $(this).html(
                    $(doc).replace(regexp,'<a href=\"http://nl.wikipedia.org/wiki/$1\">$1<\/a>'));
            });
       return $(doc); 
     });  
   }  

});

I'm not familiar with jetpack, but your jquery seems to be quite messed up.

If "doc" is an HTML document, then doing $(doc).each() doesn't really make sense. It would only loop once, and "this" would be the same as doc.

Then later you are doing $(doc).replace(regexp, ...), but replace() is not a jquery function. You might have wanted to do .html().replace(regexp, ...); HOWEVER, I do not recommend doing this because it will not work - you will just end up replacing any numbers in the document, even if they are part of another URL or the HTML of the page.
