    copied!<p>I have a table with this markup:</p> <pre><code>&lt;table&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 3&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 4&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; </code></pre> <p>Every table row is a product and some products have more information. So in this case a table looks like this:</p> <pre><code>&lt;table&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Information 1&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Information 2&lt;/td&gt;&lt;/tr&gt; &lt;tr class="odd"&gt;&lt;td&gt;Product 3&lt;/td&gt;&lt;/tr&gt; &lt;tr class="even"&gt;&lt;td&gt;Product 4&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; </code></pre> <p>I wan't to hide the rows with the product information, and show it after a click on the product row.</p> <p>I tried this with the following Javascript function and onlick="":</p> <pre><code>function showHide(id) { var el = document.getElementById(id); if( el &amp;&amp; el.style.visibility == 'hidden') el.style.visibility = 'visible'; else el.style.visibility = 'hidden'; } </code></pre> <p>But the problem is I don't know how to target only the information rows of the product I've clicked on. It would be easy if I could change the markup, but this markup is generated, so I only can solve it with Javascript.</p> <p>Is ist possible to solve this problem? I have created a fiddle, so it's easier to deliver a quick solution:</p> <p><a href="http://jsfiddle.net/emjay__/8B3M4/" rel="nofollow">http://jsfiddle.net/emjay__/8B3M4/</a></p>
