當我向下滾動頁面時讓JQuery觸發900px

Question

我有一個小的JQuery腳本，當用戶向下滾動頁面時，我想運行900px。我有這個到目前爲止：

<script> 
$(document).ready(function() {  
     $(window).on('scroll', function(){ 
      if($(window).scrollTop > 900){ 
        jQuery({ Counter: 0 }).animate({ Counter: $('.single').text() }, { 
         duration: 1000, 
         step: function() { 
         $('.single').text(Math.ceil(this.Counter)); 
         } 
        }); 

        //SEVERAL VALUES 

        $('.Count').each(function() { 
         jQuery({ Counter: 0 }).animate({ Counter: $(this).text() }, { 
         duration: 1000, 
         step: function() { 
          $(this).text(Math.ceil(this.Counter)); 
         } 
         }); 
        }); 
      } 
     });  
    }); 
    </script> 

我現在有上述但它似乎沒有工作？

你可以像下面這樣做

$(window).on('scroll', function(){ 
    if($(window).scrollTop > 900){ 
    // Your code to execute when the window is scrolled more than 900px 
    } 
});
