javascript - Youtube api -how to return nextpage token from fuction? -


using youtube api playlist items. there more 50 in list need build loop them. when button clicked i'm calling function return 50 @ time build loop items.

having problems returning nextpagetoken function. couldn't figure out way return data got point i've plugged nextpagetoken html of div inside function but, once function finishes when try html value returns blank.

the console.log('nextpagetoken: ' + data.nextpagetoken); command shows correct value.

the console.log('after call: ' + next); command shows blank value.

also, 'after call' command appears in console log before 'nextpagetoken' log.

any received. here's javascript , html:

$(document).ready(function() {     var loop=0;     var data;     var next='';  $('#get').click(function(){     getvids();     next=$('#pagetoken').text();      console.log('after call: ' + next); });            function getvids(page){     $('#results').html("");     data = {               part: 'snippet',               maxresults: 50,               playlistid: 'playlist',               key: 'mykey',               pagetoken: page             };     $.get(       "https://www.googleapis.com/youtube/v3/playlistitems", data,       function(data){         var output;         console.log('page: ' + data.nextpagetoken);         $.each(data.items, function(i, item)             {               console.log(item);               videotitle = item.snippet.title;               rvideoid = item.snippet.resourceid.videoid;               vidthumburl = item.snippet.thumbnails.high.url;               output = '<li style="list-style:none;">' + rvideoid + ' <a class="videos2 video" href="https://www.youtube.com/watch?v=' + rvideoid + '">' + videotitle + '<a/></li>';               //append results list               $('#results').append(output);             });         console.log('nextpagetoken: ' + data.nextpagetoken);         $('#pagetoken').html(data.nextpagetoken);        });          }    });
