我有一些JQuery淡入我的過濾器欄,並添加填充內容,以補償用戶是否滾動過去#contentPageSection股利。JQuery FadeIn和添加類當滾動過去div

如果過濾條被隱藏,它應該刪除填充,但在滾動時填充不斷添加。不知道如何解決這個問題。

這裏是我的問題的視頻:

這裏是與滾動交易的JQuery

// Show filter bar when scrolled past the main image. 
$(function(){ 
    var scrollTimer = null; 
    $(window).scroll(function() { 
      var st = $(this).scrollTop(); 
      var topOfTheDiv = $("#contentPageSection").offset().top; 
      if(st > topOfTheDiv) { 
       $('.careers_filter').css({position: 'fixed', top: '0px'}); 
       $('.careers_filter').stop().fadeIn(150); 
       // add padding right to content when sidebar is shown - to avoid overlapping 
       $(".contentGrid:first-child").addClass('toggleFilterPadding'); 
      }else{ 
       $('.careers_filter').stop().fadeOut(150); 
       // remove padding right to content when sidebar is hidden 
       $(".contentGrid:first-child").removeClass('toggleFilterPadding'); 
       } 
     } 

     if (scrollTimer) { 
      clearTimeout(scrollTimer); // clear any previous pending timer 
     } 
     scrollTimer = setTimeout(caughtScrollPosition, 100); // set new timer 
     updateNavigation(); 
    }); 
}) 

這裏的JQuery的是交易與過濾器欄的隱藏:

// hide or show the sidebar 
    if($(window).width() <= 992) { 
     $("#filter_overlay").removeClass('showSideBar').addClass('hideSideBar'); 
     $("#filter_overlay").children().children("span").removeClass('rightArrow').addClass('leftArrow'); 
    } 

    $('.filterHideButton').on('click', function(){ 
     $("#filter_overlay").toggleClass('showSideBar').toggleClass('hideSideBar'); 
     $(".contentGrid:first-child").toggleClass('toggleFilterPadding'); 
     $("#filter_overlay").children("#toggleSidebar").children("span").toggleClass('leftArrow').toggleClass('rightArrow'); 

    }); 
});

你可以剪切和查看源代碼或通過瀏覽器檢查粘貼代碼? – lharby

好點:)添加在HTML – Madness

我相信它是因爲你一旦添加填充就不會停止填充。一旦你到了添加填充的位置,它會一直進入,如果阻止每個滾動事件,直到st小於topOfTheDiv通過滾動備份。您可以使用旗語的是這樣的:

// Show filter bar when scrolled past the main image. 
$(function(){ 
    var scrollTimer = null; 
    var paddingAdded = false; 
    $(window).scroll(function() { 
      var st = $(this).scrollTop(); 
      var topOfTheDiv = $("#contentPageSection").offset().top; 
      if(st > topOfTheDiv && !paddingAdded) { 
       $('.careers_filter').css({position: 'fixed', top: '0px'}); 
       $('.careers_filter').stop().fadeIn(150); 
       // add padding right to content when sidebar is shown - to avoid overlapping 
       $(".contentGrid:first-child").addClass('toggleFilterPadding'); 
       paddingAdded = true; 
      } 
      if(st <= topOfTheDiv && paddingAdded) { 
       $('.careers_filter').stop().fadeOut(150); 
       // remove padding right to content when sidebar is hidden 
       $(".contentGrid:first-child").removeClass('toggleFilterPadding'); 
       paddingAdded = false; 
      } 
     } <-- extra bracket 

     if (scrollTimer) { 
      clearTimeout(scrollTimer); // clear any previous pending timer 
     } 
     scrollTimer = setTimeout(caughtScrollPosition, 100); // set new timer 
     updateNavigation(); 
    }); 
})

有道理你在說什麼,但不幸的是這個例子不起作用。側欄完全不顯示。 – Madness

其實,我相信你的代碼中存在錯字。一個額外的支架。 scrollTimer應該在滾動回調中嗎?指向額外支架的答案已更新。 – AtheistP3ace

@Madness添加了一個額外的代碼中斷支架刪除小提琴。這是否像你期望的那樣?顯然很多CSS在這裏失蹤。 – AtheistP3ace
