ssl cert and 3rd party validation...is this possible?

I have a website that is http except for one link which is https. I want to be able to build an application that once the https link is clicked, it will capture a users client-side certificate, send that client-side certificate data to a 3rd party validator and if success, the user will be able to see the content on the link. Can I do that using Javascript or jquery .ajax call? If so, how? This is the code I have so far. Its missing some data because I am not sure how to capture it. I tried to note the missing data by /* MISSING DATA COMMENT */ 

$.ajax ({ url:'https:somelink.com/2013/05/22/someSSLonlyDoc.pdf', type: 'HEAD', error:function () {alert('no link today');}, success: function (){ $('#jsclass').append('<li><a target="_new" herf =https:somelink.com/2013/05/22/someSSLonlyDoc.pdf>SSLonlyLInk</a></li>'); 
/* **MISSING DATA** NEED TO SOMEHOW CAPTURE A USERS SSL CERT AND SEND DATA TO 3RD PARTY LINK TO VALIDATE */
 
var
 sslLink = 'https://some.3rd.party.validator.com'; $ajax ({ url: sslLInk, crossDomain: true, type:'Post', data: ***USER SSL Cert needed here**, success: function(data){ alert('user has passed'); /*some how activates link*/ }, error: function (data){alert ('fail');}, },
I hope someone can help. I have been trying to do this for days and cant come up with a solution. Thanks in Advance!!
