javascript - Inconstant panel placement with jquery + bootstrap -


i building custom rss dashboard , iterating on array of feeds , throwing them google service.

but when @ panels not in order consistently.

code:

jquery

 var rssarray = [   'https://blog.malwarebytes.org/feed/',   'http://krebsonsecurity.com/feed/',   'http://motherboard.vice.com/rss?trk_source=motherboard',   'https://www.trustwave.com/rss.aspx?type=twblog',   'http://threatpost.com/feed/',   'https://news.ycombinator.com/rss',   'http://feeds.trendmicro.com/trendmicrosimplysecurity?format=xml',   'https://securityintelligence.com/topics/vulnerabilities-threats/feed/',   'https://securityintelligence.com/topics/x-force/feed/' ]    (var i=0; < rssarray.length; i++){      $.ajax({        url: 'https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=5&callback=?&q=' + encodeuricomponent(rssarray[i]),        datatype: 'json',        success: function(data) {         //  console.log(data)          var feedbody = $('<div>', {class: 'panel-body'})          var feedhead = $('<div>', {class: 'panel-heading', html: '<h3 class="panel-title text-center">'+capitalisefirstletter(data.responsedata.feed.title)+'</h3>'})          var contentholder = $('<ul>', {class: 'list-group'})          var feed = $('<div>', {class: 'col-xs-6 col-md-4 panel panel-warning'}).append(feedhead).append(feedbody).append(contentholder)          $.each(data.responsedata.feed.entries, function(key, value){            if (value.contentsnippet === "comments"){              var thehtml = '<a href="'+value.link+'" target="_blank" class="list-group-item"><h5 class="list-group-item-heading">'+value.title+'</h5></a>';            } else {              var thehtml = '<a href="'+value.link+'" target="_blank" class="list-group-item"><h5 class="list-group-item-heading">'+value.title+'</h5><p class="list-group-item-text">'+value.contentsnippet+'</p></a>';            }            feedbody.append(thehtml)          });         $("#content").append(feed)        }     })  }

html

  <div class="row">     <div id="content">     </div>   </div>

examples of issues:

enter image description here enter image description here

you're kicking off series of ajax calls, will execute unknown amount of time. when complete call success callbacks.

if first request takes 5 seconds, third request takes 2, third request rendered before first.

if need ensure these requests have completed before rendering contents, use $.when create promise (jquery deferred actually) , render data when has resolved.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
