html - How to call a function for each element with a particular class, every time the window scrolls (jquery)) -


i trying make scroll-triggered function slides elements in 1 side based on scroll position. run on elements 'my-class', code seems think 'this' window, not each 'my-class' element. there wrong way calling function? how can each element run function?

here basic html structure:

<div class="wrapper">     <div class="my-class"></div>     <div class="not-my-class"></div>     <div class="my-class"></div>     <div class="not-my-class"></div>     <div class="my-class"></div> </div>

some css:

.wrapper {     width: 100%;     height: 100%; } .my-class, .not-my-class {     width: 100%;     height: 350px;     margin-top: 10px;     background-color: #888888; }

and jquery:

function fadein($element) { $scrolltop = $(window).scrolltop(); $windowheight = $(window).height(); $pageheight = $('body').height(); $elementheight = $($element).height(); $baseoffset = $($element).offset().top; $length = 100; $finaloffset = $baseoffset + ( $elementheight / 2 ); $current = ( $scrolltop - ( $finaloffset - ($windowheight / 2 ) - ( $length / 2 ) ) ) / $length; if ($current > 1) {     $current = 1; } else {     if ($current < 0) {         $current = 0;     }     else {} } $opacity = $current; $slide = ( $current * 100 ) - 100; $(this).css({"opacity": $opacity, "left": $slide, "position": "relative"}); } $(window).on("load resize scroll",function(){     $('.my-class').each(fadein(this)); });

you need pass in function so:

$('.my-class').each(function(){    fadein(this)  });

so this referring .my-class element instead of window

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
