    <p>I'm currently fighting a fierce battle with an interface I'm trying to put together. I'm pretty decent at CSS &amp; XHTML, but my jQuery/JavaScript skills are not too impressive. What I'm looking for is not so much a strict answer, but some hints on how to go about these kinds of tasks. </p> <p>What I am trying to achieve is a layout with some boxes in the main-content area that can be expanded and collapsed when the user press either a link in the sidebar or on a header on the box itself. </p> <p><a href="http://www.timkjaerlange.com/foobar/example-dashboard-v01.gif" rel="nofollow noreferrer">dashboard http://www.timkjaerlange.com/foobar/example-dashboard-v01.gif</a></p> <p>Furthermore I want the browser to remember what box was expanded last by setting a cookie. If that wasn't enough I also want to be able to add a "limited"-class to each box and thereby disabling it, and it's corresponding sidebar-list-item.</p> <p>Also I want the box to have a class based on it's state (expanded, collapsed, limited).</p> <p>This is my markup:</p> <pre><code>&lt;!-- S I D E B A R - L E F T --&gt; &lt;div id="sidebar-left"&gt; &lt;ul class="sidebar-menu-1"&gt; &lt;li&gt;&lt;strong&gt;List headline&lt;/strong&gt; &lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Open module 1&lt;/a&gt; &lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Open module 2&lt;/a&gt; &lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Open module 3&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/div&gt;&lt;!--/sidebar-left--&gt; &lt;!-- M A I N - C O N T E N T --&gt; &lt;div id="main-content"&gt; &lt;!-- dashboard-module --&gt; &lt;div class="dashboard-module"&gt; &lt;div class="dashboard-module-content limited"&gt; &lt;h2&gt;Headline 1&lt;/h2&gt; &lt;p class="teaser"&gt;Teaser-text 1&lt;/p&gt; &lt;div class="expand-collapse"&gt; [some content] ´ &lt;/div&gt; &lt;/div&gt; &lt;/div&gt;&lt;!--/dashboard-module--&gt; &lt;!-- dashboard-module --&gt; &lt;div class="dashboard-module"&gt; &lt;div class="dashboard-module-content limited"&gt; &lt;h2&gt;Headline 2&lt;/h2&gt; &lt;p class="teaser"&gt;Teaser-text 2&lt;/p&gt; &lt;div class="expand-collapse"&gt; [some content] ´ &lt;/div&gt; &lt;/div&gt; &lt;/div&gt;&lt;!--/dashboard-module--&gt; &lt;!-- dashboard-module --&gt; &lt;div class="dashboard-module"&gt; &lt;div class="dashboard-module-content limited"&gt; &lt;h2&gt;Headline 3&lt;/h2&gt; &lt;p class="teaser"&gt;Teaser-text 3&lt;/p&gt; &lt;div class="expand-collapse"&gt; [some content] ´ &lt;/div&gt; &lt;/div&gt; &lt;/div&gt;&lt;!--/dashboard-module--&gt; &lt;/div&gt;&lt;!--/main-content--&gt; </code></pre> <p>And this is my jQuery: </p> <pre><code>// If the dashboard-module is "limited" do this: $('div[class*=limited]').each( function(index) { var countFix = $('div.dashboard-module-content').index(this); var countFixPlusTwo = countFix + 2; $( 'ul.sidebar-menu-1 li:nth-child(' + countFixPlusTwo + ')' ).unbind('click').removeClass('selected').addClass('sidebar-menu-locked'); $(this).parent('.dashboard-module').find('h2').unbind('click'); $(this).find('.expand-collapse').remove(); $(this).find('.dashboard-module p:hidden').show(); $(this).addClass('limited-btn'); }); // Check for cookies and do stuff accordingly: var cookieTest = $.cookie("cookie"); if(cookieTest == null){ $('.js-hidden').hide(); $('ul.sidebar-menu-1 li:not(.sidebar-menu-locked):eq(1)').addClass('selected'); $('.dashboard-module-content:not(.limited):eq(0)' ).toggleClass('hide-btn'); $('.dashboard-module-content:not(.limited):not(:eq(0))' ).removeClass('hide-btn'); $('.expand-collapse:eq(0)' ).show(); }; if(cookieTest != null){ var cookieTestPlusTwo = parseInt(cookieTest, 10) + 2; $('.dashboard-module-content:eq(' + cookieTest + ')' ).toggleClass('hide-btn'); $('.dashboard-module-content:not(:eq(' + cookieTest + '))' ).removeClass('hide-btn'); $('ul.sidebar-menu-1 li:nth-child(' + cookieTestPlusTwo + '):not(.sidebar-menu-locked)').addClass('selected'); $('ul.sidebar-menu-1 li:not(:nth-child(' + cookieTestPlusTwo + '))').removeClass('selected'); $('.expand-collapse:eq(' + cookieTest + ')' ).show(); $('.expand-collapse:not(:eq(' + cookieTest + '))').hide(); }; // When clicking dashboard-module headers do stuff: $('.dashboard-module h2:not(.limited h2):not(.tooltip h2)').click(function(index) { var indexFoo = $('.dashboard-module h2:not(.tooltip h2)').index(this); var indexPlusTwo = indexFoo + 2; var indexCookie = indexFoo; $.cookie("cookie", indexCookie, { expires: 7 }); $('.dashboard-module-content:eq(' + indexFoo + ')').toggleClass('hide-btn'); $('.dashboard-module-content:not(:eq(' + indexFoo + '))' ).removeClass('hide-btn'); $('ul.sidebar-menu-1 li:nth-child(' + indexPlusTwo + ')').addClass('selected'); $('ul.sidebar-menu-1 li:not(:nth-child(' + indexPlusTwo + '))').removeClass('selected'); $('.dashboard-module-content:eq(' + indexFoo + ') .expand-collapse').toggle('fast'); $('.dashboard-module-content:not(:eq(' + indexFoo + ')) .expand-collapse').hide('fast'); $('.dashboard-module-content:not(.limited)').each( function(){ if($(this).parent('.dashboard-module').find('.hide-btn').length == 0){ $(this).find('p.teaser').show(); } else { $(this).find('p.teaser').hide(); } }); }); // When clicking sidebar list-items do stuff: $('.sidebar-menu-1 li:not(.sidebar-menu-locked)').click(function(index) { var indexFoo = ($('.sidebar-menu-1 li').index(this) - 1); var indexPlusTwo = indexFoo + 2; var indexCookie = indexFoo; $.cookie("cookie", indexCookie, { expires: 7 }); $('.dashboard-module-content:eq(' + indexFoo + ')').toggleClass('hide-btn'); $('.dashboard-module-content:not(:eq(' + indexFoo + '))' ).removeClass('hide-btn'); $('ul.sidebar-menu-1 li:nth-child(' + indexPlusTwo + ')').addClass('selected'); $('ul.sidebar-menu-1 li:not(:nth-child(' + indexPlusTwo + '))').removeClass('selected'); $('.dashboard-module-content:eq(' + indexFoo + ') .expand-collapse').toggle('fast'); $('.dashboard-module-content:not(:eq(' + indexFoo + ')) .expand-collapse').hide('fast'); $('.dashboard-module-content:not(.limited)').each( function(){ if($(this).parent('.dashboard-module:not(.limited)').find('.hide-btn').length == 0){ $(this).find('p.teaser').show(); } else { $(this).find('p.teaser').hide(); } }); }); </code></pre> <p>As for now it all works in FF, but in IE7+8 it doesn't. But my question is not so much about how to make it work in IE, but more on how you would go about this kind of task? I suspect that my jQuery is not exactly DRY, but how do I condense it?</p> <p>How would you write and organize your code? Sorry if this is a too broad and long-winded question, but I'm really interested in how experienced jQuery designers go about challenges like this one.</p> <p><strong>Update:</strong> Thanks to Tatu Ulmanen's help I've managed to put together this: <a href="http://timkjaerlange.com/foobar/jquery-test/index.html" rel="nofollow noreferrer">http://timkjaerlange.com/foobar/jquery-test/index.html</a></p>

    1. COYour question is overwhelming. At least to me. I suggest you cut your bundle into small questions. For instance leaving out the cookie sub-question.

    2. COSorry but this comes across as a "do my work for me" kind of question. You should break it down into the three or so questions that are here and reduce those to the minimal code necessary.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
