不能在jQuery中

Question

我想打電話的時候被觸發滾動事件的函數開火（「滾動」）事件，這是我使用的代碼：

$(window).on('scroll', function(){ 
     alert("Scroll event is triggered."); 
}); 

問題是，當我滾動窗戶，什麼都不會發生，但是當我更改爲「點擊」或「調整」的情況下，上面的代碼工作得很好：

$(window).on('click', function(){ 
     alert("The page was clicked."); 
    }); 

$(window).on('resize', function(){ 
     alert("The window was resized."); 
    }); 

那麼，爲什麼「點擊」和「調整」事件工作和「滾動'沒有？我試過

$(window).scroll(function(){ 
    alert("Scroll event is triggered."); 
}); 

它也沒有工作。我錯過了什麼？

感謝

確保您inculde jQuery庫，並使用您的代碼，當文檔準備好

$(function(){ 
 
    $(window).scroll(function(){ 
 
    console.log('scrolling ') 
 
    }); 
 
});

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.Lorem Ipsum is simply dummy text of the printing and typesetting industry.

看來這個問題是不是代碼，但畢竟在瀏覽器中。所以當我清除瀏覽數據時，代碼運行得很好。

謝謝你們。
