Linking to bookmarklet

I’m trying to link to a bookmarklet in my post. The link I have looks like this:

<a href="setTimeout('x99.focus()',300);var%20re=/([\/-]|is[bs]n=)(\d{7,9}[\dX])/i;if(re.test(location.href)==true){var%20isbn=RegExp.$2;var%20x99=window.open('https://catalog.denverlibrary.org/search/searchresults.aspx?ctx=1.1033.0.0.6&type=Keyword&term='+isbn,'LibraryLookup','scrollbars=1,resizable=1,top=0,left=0,location=1,width=800,height=600');x99.focus();}">More links here</a>

but the bookmarklet code keeps getting the blog url slpped in front of it some how (see below)

www.artifacting.com/setTimeout('x99.focus()',300);var re=/([//-]%7Cis[bs]n=)(/d%7B7,9%7D[/dX])/i;if(re.test(location.href)==true)%7Bvar isbn=RegExp.$2;var x99=window.open('https://catalog.denverlibrary.org/search/searchresults.aspx?ctx=1.1033.0.0.6&type=Keyword&term='+isbn,'LibraryLookup','scrollbars=1,resizable=1,top=0,left=0,location=1,width=800,height=600');x99.focus();}}

Could somebody help me figure out how to fix this?

Thanks
