    copied!<p>I have the following html file :</p> <pre><code>&lt;div id="tour"&gt; &lt;h2&gt;Paris, France Tour&lt;/h2&gt; &lt;p&gt;$2,499 for 7 Nights&lt;/p&gt; &lt;button&gt;See photos from our last tour&lt;/button&gt; &lt;ul class="photos"&gt; &lt;li&gt; &lt;img src="/assets/photos/paris1.jpg"&gt; &lt;span&gt;Arc de Triomphe&lt;/span&gt; &lt;/li&gt; &lt;li&gt; &lt;img src="/assets/photos/paris2.jpg"&gt; &lt;span&gt;The Eiffel Tower&lt;/span&gt; &lt;/li&gt; &lt;li&gt; &lt;img src="/assets/photos/paris3.jpg"&gt; &lt;span&gt;Notre Dame de Paris&lt;/span&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p>This is my jQuery code :</p> <pre><code>function showPhotos() { $(this).find("span").slideToggle(); } $(document).ready(function() { $("#tour").on("click", "button", function() { $(".photos").slideToggle(); }); $(".photos").on("mouseenter", "li", showPhotos); $('.photos').on("mouseleave", "li", showPhotos); }); </code></pre> <p>This code works, it shows the span when mouse enters the img element . But when I try to do the same thing like so :</p> <pre><code>function showPhotos() { $(this).find("span").slideToggle(); } $(document).ready(function() { $("#tour").on("click", "button", function() { $(".photos").slideToggle(); }); $(".photos").on("mouseenter", "li", function() { showPhotos(); }); $('.photos').on("mouseleave", "li", function() { showPhotos(); }); }); </code></pre> <p>It doesn't work . With my limited knowledge, both codes seem to be doing the same thing. Please help me, How is the second code different from the first ? </p>
