javascript - Tracking facebooklike button on my website -


i have video in site before playing video, visitor must facebook page. problem when come website not see video again because button in inactive. i'm using javascript. thank understanding , i'm waiting help

function setcookie(c_name, value, expiredays) { var exdate = new date(); exdate.setdate(exdate.getdate() + expiredays); document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.togmtstring()); } function getcookie(c_name) { if(document.cookie.length > 0) { c_start = document.cookie.indexof(c_name + "="); if(c_start != -1) { c_start = c_start + c_name.length + 1; c_end = document.cookie.indexof(";", c_start); if(c_end == -1) c_end = document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } function lecture_vid() { var cc = '<iframe class="youtube-player" type="text/html" width="640" height="400" src="http://www.youtube.com/embed/iasjjskawvc?autoplay=1" frameborder="0"></iframe>'; $("#vid_real").html(cc); } fb.event.subscribe('edge.create', function(href, widget) { setcookie('edgetv', '1', 350); faceclick(); }); function faceclick() { lecture_vid(); $('#confirme_jaime').empty().hide(); }

if want know if user liked page when being outside of facebook (meaning not in canvas/page tab app), have have user connect app, , permission read likes.

this might little on top want achieve (i wouldn’t connect app see video).

so other option safe info user has clicked button on page kind of database.

but still not give info work users have liked page before – have unlike page , again. bad user experience them, , bad page, because facebook might take unliking/liking, if happens multiple times 1 user, consideration when determining page’s ranking …
