/* Title: window scroll event
* Description: avoid attaching handlers to the window scroll event
*/
// antipattern
$(window).scroll(function () {
$('.foo').something();
});
// preferred
var outerPane = $details.find(".details-pane-outer"),
didScroll = false;
$(window).scroll(function () {
didScroll = true;
});

if (didScroll) {
didScroll = false;
// Check your page position and then
// Load in more results
// outerPane.html();
}
}, 250);
// preferred v2, timeout instead of interval - no unnecessary ticks
var scrollTimeout; // global for any pending scrollTimeout
var outerPane = $details.find(".details-pane-outer");
$(window).scroll(function () {
if (scrollTimeout) {
// clear the timeout, if one is pending
