javascript - waypoint addClass and remove class of a "fixed" element works when going down but doesn't going up -


i'm working on website parallax effect using stellar: http://webdesign.tutsplus.com/tutorials/complete-websites/create-a-parallax-scrolling-website-using-stellar-js/

i've got "fixed" div class @ center of page. when scroll down or class changes depending on slide "active".

i'm using waypoint , works fine when i'm scrolling down page. when scroll up, instead of changing class, put 1 after other, order shifted , class doesn't match right slide.

here html (#square fixed div):

<body>  <ul class="navigation"> <li id="un"     data-slide="1">slide 1</li> <li id="deux"   data-slide="2">slide 2</li> <li id="trois"  data-slide="3">slide 3</li> <li id="quatre" data-slide="4">slide 4</li> <li id="cinq"   data-slide="5">slide 5</li> <li id="six"    data-slide="6">slide 6</li> <li id="sept"   data-slide="7">slide 7</li> <li id="huit"   data-slide="8">slide 8</li> <li id="neuf"   data-slide="9">slide 9</li> <li id="dix"    data-slide="10">slide 10</li> <li id="onze"   data-slide="11">slide 11</li> </ul>  <div id="square" class="trans1"></div>  <div class="slide" id="slide1" data-slide="1" data-stellar-background-ratio="0.5"> <a class="button" data-slide="2" title=""></a>  </div><!--end slide 1-->  <div class="slide" id="slide2" data-slide="2" data-stellar-background-ratio="0.5">     <div class="wrapper">       <img src="images/slide2/blur-ball.png" data-stellar-ratio="3" data-stellar-vertical-offset="-55"alt="">       <img src="images/slide2/blur-ball-big.png" data-stellar-ratio="1" data-stellar-vertical-offset="-102"alt="">    </div>     <span class="slideno">slide 2</span>    <a class="button" data-slide="3" title=""></a>  </div><!--end slide 2-->   <div class="slide" id="slide3" data-slide="3" data-stellar-background-ratio="0.5">    <div class="wrapper">    <img src="images/slide3/freelance.png" data-stellar-ratio="1.4" data-stellar-vertical-offset="-102"alt="">    <img src="images/slide3/psdtuts.png" data-stellar-ratio="1.5" data-stellar-vertical-offset="-53"alt="">    <img src="images/slide3/rockable.png" data-stellar-ratio="2.7" data-stellar-vertical-offset="-200"alt="">    <img src="images/slide3/themeforest.png" data-stellar-ratio="3" data-stellar-vertical-offset="-200"alt="">    <img src="images/slide3/tutshub.png" data-stellar-ratio="1" data-stellar-vertical-offset="-200"alt="">    <img src="images/slide3/psdtuts.png" data-stellar-ratio="1.5" data-stellar-vertical-offset="-200"alt="">    </div>     <span class="slideno">slide 3</span>    <a class="button" data-slide="4" title=""></a>  </div><!--end slide 3-->  <div class="slide" id="slide4" data-slide="4" data-stellar-background-ratio="0">     <span class="slideno">slide 4</span>    <span class="parallaxbg">use parallax effects on background images too!</span>  </div><!--end slide 4-->

and here javascript

//1st slide     $('#square').waypoint(function(direction) {         if (direction === 'down') {         $('#square').toggleclass('trans1');     }     else {         $('#square').toggleclass('trans1');     }     });      // 2nd slide     $('#slide2').waypoint(function(direction) {         if (direction === 'down') {         $('#square').toggleclass('trans2'), $('#square').removeclass('trans1');     }     else {         $('#square').toggleclass('trans2'), $('#square').removeclass('trans1');     }     }, { offset: '50%' });          $('#slide2').waypoint(function(direction) {             if (direction === 'up') {             $('#square').toggleclass('trans1'),$('#square').removeclass('trans2');         }         });     //3rd slide    $('#slide3').waypoint(function(direction) {         if (direction === 'down') {         $('#square').toggleclass('trans3'),$('#square').removeclass('trans2');     }     else {         $('#square').toggleclass('trans3'),$('#square').removeclass('trans2');     }}, { offset: '50%' });          $('#slide3').waypoint(function(direction) {                 if (direction === 'up') {             $('#square').toggleclass('trans2'),$('#square').removeclass('trans3');             }         });      //4th slide     $('#slide4').waypoint(function(direction) {         if (direction === 'down') {         $('#square').toggleclass('trans4'),$('#square').removeclass('trans3');     }     else {         $('#square').toggleclass('trans4'),$('#square').removeclass('trans3');     }}, { offset: '50%' });          $('#slide4').waypoint(function(direction) {                 if (direction === 'up') {             $('#square').toggleclass('trans3'),$('#square').removeclass('trans4');             }         });

thanks

having created portfolio site (http://anti-code.com) crazy stuff along parallax scrolling in directions, way have code structured done far more object oriented, , make things less repetitive.

but besides that. issue having because not removing classes. toggling ones each slide.

so example, instances have this:

   $('#square').toggleclass('trans2'),$('#square').removeclass('trans3');

could changed work properly:

  $('#square').removeattr('class').addclass('trans2');

if makes sense. aren't changing class otherwise, you're toggling on different trans# class name on square element. if remove class attribute first before toggling it, , add classname want turn on work.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
