javascript - Jquery fadeIn in callback for fadeOut not lasting -

-

hope can shed light on issue me.... i'm using setinterval alternate displaying headlines on webpage. fades out previous one, in callback function fades in new one. used work fine, separated callback function fadeout because wanted run without delay, , i'm getting initial headline, when comes time change, fade in split second , disappear again.

       function processsidebar(data) {             var headlines = $.parsejson(data);             var sindex = 0;              function newsidebar(surl, sindex) {                 $(".sidebar").html(headlines[sindex].date + '<br><a href="' + surl + '">' + headlines[sindex].line + '</a>');                 $(".sidebar").fadein(400);             }             newsidebar("getme.php?blog=1&headline=1", sindex);              setinterval(function() {                 ++sindex;                 if (sindex == headlines.length) {sindex = 0}                 var surl="getme.php?blog=1&headline=" + headlines[sindex].index;                 $(".sidebar").fadeout(400,newsidebar(surl,sindex));             }, 10000); // end setinterval          }; // end processsidebar

jquery's fadeout wants function complete argument.

you're giving newsidebar(surl,sindex), gets evaluated , returns nothing (but whole fadein stuff).

you want use anonymous function:

$(".sidebar").fadeout(400,function() { newsidebar(surl,sindex) });
