jQuery沒有生成所需的輸出頁

所以我很新的jQuery，我試圖在我的投資組合網站中使用它。從我可以告訴我的代碼應該產生一些輸出，當我懸停在我的投資組合窗口窗口，但是當我嘗試這個......沒有任何反應。我想知道是否有人知道我錯過了什麼，或者沒有正確地做正確的事情，導致這種情況。jQuery沒有生成所需的輸出頁

$(this).children('overlay') jQuery的，CSS和HTML是錯在你的代碼中，有一個由名稱的覆蓋沒有標籤，你要選擇具有類覆蓋的元素，所以你需要使用.overlay。

$(document).ready(function() { 
 

 
    //mouseenter overlay 
 
    $('ul#gallery li').on('mouseenter', function() { 
 

 
    // Get data attribute values 
 
    var title = $(this).children().data('title'); 
 
    var desc = $(this).children().data('desc'); 
 

 
    //validation 
 
    if (desc == null) { 
 
     desc = 'Click To Enlarge'; 
 
    } 
 

 
    if (title == null) { 
 
     title = ''; 
 
    } 
 

 
    //Create overlay div 
 
    $(this).append('<div class="overlay"></div>'); 
 

 
    //Get the overlay div 
 
    var overlay = $(this).children('.overlay'); 
 

 
    // Add html to overlay 
 
    overlay.html('<h3>' + title + '</h3><p>' + desc + '</p>'); 
 

 
    // Fade in overlay 
 
    overlay.fadeIn(800); 
 
    }); 
 

 
    $('ul#gallery li').on('mouseleave', function() { 
 

 
    //Create overlay div 
 
    $(this).append('<div class="overlay"></div>'); 
 

 
    //Get the overlay div 
 
    var overlay = $(this).children('.overlay'); 
 

 
    //Fade out overlay 
 
    overlay.fadeOut(500); 
 
    });
