Question

In my header I load scripts (I keep this scripts on my server, original links are added here just for you):

<script src="http://jscrollpane.kelvinluck.com/script/jquery.mousewheel.js"></script>
<script src="http://jscrollpane.kelvinluck.com/script/mwheelIntent.js"></script>
<script src="http://jscrollpane.kelvinluck.com/script/jquery.jscrollpane.min.js">

Then on my footer I’m executing some code:

$(document).ready(function() {
            $(function(){
                $('.scroll-pane').load().jScrollPane();
            });
            numOfPics = $('#gallery-wraper img').size();
            widthOfAll = 0;
            $('#gallery-wraper img').each(function() {
                imgWidth = $(this).width() + 20;
                widthOfAll += imgWidth;
            }); // end of each
            $("#gallery-container").load().css("width",widthOfAll);

            galleryPosition = $(window).height() / 2 - 250;
            $("#gallery").css("margin-top", galleryPosition);
});// end of document.ready()

I want it yo display my images horizontally and put it inside jScrollPane (http://jscrollpane.kelvinluck.com/)
But it displays my images horizontally after refresh only (or even after a few page refreshes in chrome). It looks like it tries to execute my code before page content is generated (its a wordpress theme) or before scroll libraries are loaded. What is wrong with my logic here? I’m using document.ready() so why it acts this way?

Answer 1

Try calling it after the page loads

$(document).ready(function() {
  $(function(){
      $('.scroll-pane').load().jScrollPane();
  });
  function updateCSS() {
    numOfPics = $('#gallery-wraper img').size();
    widthOfAll = 0;
    $('#gallery-wraper img').each(function() {
        imgWidth = $(this).width() + 20;
        widthOfAll += imgWidth;
    }); // end of each
    $("#gallery-container").load().css("width",widthOfAll);

    galleryPosition = $(window).height() / 2 - 250;
    $("#gallery").css("margin-top", galleryPosition);
  }

  setTimeout('updateCSS()',100);
});// end of document.ready()
