Get links to Share-messages in social networks?

Question

JavaScript

Wrote a simple script for share in social networks.

var Share = {
        vkontakte: function() {
            url  = 'http://vkontakte.ru/share.php?';
            url += 'url='          + encodeURIComponent(seo.purl);
            url += '&title='       + encodeURIComponent(seo.ptitle);
            url += '&description=' + encodeURIComponent(seo.text);
            url +=(seo.pimg!=''? '&image='       + encodeURIComponent(seo.pimg):'');
            url += '&noparse=true';
            Share.popup(url);
        },
        odnoklassniki: function() {
            url  = 'http://www.odnoklassniki.ru/dk?st.cmd=addShare&st.s=1';
            url += '&st.comments=' + encodeURIComponent(seo.text);
            url += '&st._surl='    + encodeURIComponent(seo.purl);
            Share.popup(url);
        },
        facebook: function() {
            url  = 'http://www.facebook.com/sharer.php?m2w&s=100';
           // url += '&p[title]='     + encodeURIComponent(seo.ptitle);
            //url += '&p[summary]='   + encodeURIComponent(seo.text);
            url += '&p[url]='       + encodeURIComponent(seo.purl);
            url +=(seo.pimg!=''?'&p[images][0]=' + encodeURIComponent(seo.pimg):'');


            console.log(url);
            Share.popup(url);
        },
        twitter: function() {
            url  = 'http://twitter.com/share?';
            url += 'text='      + encodeURIComponent(seo.ptitle);
            url += '&url='      + encodeURIComponent( seo.purl);
            url += '&counturl=' + encodeURIComponent( seo.purl);
            Share.popup(url);
        },
        mailru: function() {
            url  = 'http://connect.mail.ru/share?';
            url += 'url='          + encodeURIComponent(seo.purl);
            url += '&title='       + encodeURIComponent(seo.ptitle);
            url += '&description=' + encodeURIComponent(seo.text);
            url +=(seo.pimg!=''? '&imageurl='    + encodeURIComponent(seo.pimg):'');
            Share.popup(url)
        },

        popup: function(url) {
            var pop = window.open(url,'','toolbar=0,status=0,width=626,height=436');

            pop.onunload = function(e) {
                alert('Please press the Logout button to logout.') ;
            };
            var oauthInterval = window.setInterval(function(){
                if (pop.closed) {
                    window.clearInterval(oauthInterval);
                    console.log('window closed');
                }
            }, 1000);
        }
    };
$(document).ready(function(){
    $('.share-fb').click(function(){ Share.facebook();return false;});
   $('.share-vk').click(function(){Share.vkontakte();return false;});
    $('.share-tw').click(function(){Share.twitter();return false; });
});

Posts are published, everything is fine, but there was a request from the customer: "how to get links to published posts?"
If with Twitter it was easy enough to use the search https://twitter.com/search?f=tweets&q=https://Isko... and everything is ok, then everything is sad with facebook and vkontakte.
Tell me how it is possible to find posts with an attached url?

Answer 1

Vkontakte has a search for posts with the mention of the desired url, right on their website.
Ps you did not write the script, but copied it from the Internet;) without changing anything directly.
