當我將鼠標懸停在此頁面上的圖片上時，我應該將上面較大的 div 元素的 src 屬性更新為我當前懸停在其上的圖像的圖像 url。我的斷點達到"$('#image').on('懸停', function() {"行，但實際上不會在下一行設置 div 元素的 url 屬性。任何指針？function upDate(previewPic) { let newUrl = previewPic.src; $('#image').on('hover', function() { $('#image').attr("url", newUrl); });};<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script><div id="image"> Hover over an image below to display here.</div><img alt="Batter is ready" class="preview" onmouseout="unDo()" onmouseover="upDate(this)" src="https://cdn.sallysbakingaddiction.com/wp-content/uploads/2017/06/moist-chocolate-cupcakes-7.jpg"><img alt="Perfect Baking" class="preview" onmouseout="unDo()" onmouseover="upDate(this)" src="https://cdn.sallysbakingaddiction.com/wp-content/uploads/2017/06/moist-chocolate-cupcakes-6.jpg"><img alt="Yummy yummy cup cake" class="preview" onmouseout="unDo()" onmouseover="upDate(this)" src="https://cdn.sallysbakingaddiction.com/wp-content/uploads/2017/06/moist-chocolate-cupcakes-5.jpg">
