copied!<p>I'd recommend using jQuery's <code>hide</code> and <code>show</code> functions, as well as the <code>on</code> function for event handling. jQuery's main power is that it makes things "just work" across browsers, so using <code>hide</code> will let the library choose what to do in order to make that action happen, rather then you having to second guess yourself. Example:</p> <pre><code>$('#firstClicked').hide(); $('#first').on('click',function() { $('#firstClicked').show(); }); </code></pre> <p>In addition, in your original code, you have a few mistakes:</p> <pre><code>$('firstClicked').css('visiblilty','hidden'); // should be: $('#firstClicked').css('visibility','hidden'); </code></pre> <p>However, as you're worried about having to duplicate your code, you could do the following:</p> <p>HTML:</p> <pre><code><table> <tr> <td id="first" class="clickable">itemOne</td> <td id="firstClicked"><div class="initiallyHidden">itemOneInfo</div></td> </tr> <tr> <td id="second" class="clickable">itemTwo</td> <td id="secondClicked"><div class="initiallyHidden">itemTwoInfo</div></td> </tr> </table> </code></pre> <p>JS:</p> <pre><code>$('.initiallyHidden').hide(); $('.clickable').on('click',function() { $(this).siblings("td").children(".initiallyHidden").show(); }); </code></pre> <p>This way any element with a class <code>clickable</code>, when clicked, will look for a sibling with class <code>initiallyHidden</code> and show it</p> <p>Edit: Updated example to deal with the issue raised in Christophe's comment.</p>
