    <p>I can not seem to find a way of jQuery understanding the current position of an element. I scroll through some markup using the html and css, jQuery below (like a gallery - but I dont want to use any plugins) but need to find the last and first positions so it does not continiually let someone scroll content off the page - currently I am just colouring the parent container when applying an action but will swap this out in live to not show or grey out the pagination/scroll buttons. </p> <p>The scrolling works by adjusting by 209px or -209px just does not understand the position of first and last elements (li's). I am trying to stop the previous button working if there are no more previous li's and vice versa - like I said only colouring the parent for now for visual. There could be any number of li's in this as they get dynamically spat out. Attached fiddle URL too: <a href="http://jsfiddle.net/jambo/zLSUT/" rel="nofollow">http://jsfiddle.net/jambo/zLSUT/</a> Apologies for images not working in this demo. So to recap - need to stop pagination in the direction where there will be no more content to view. Hope that makes sense, thank you in advance.</p> <p>css</p> <pre><code> .smartH{ float: left; position: relative; width:10000px; height: 80px; padding: 5px 0; font-family: arial; background: #fff; } .smartH a{ float: left; text-decoration: none; cursor:pointer; } .smartH img{ float: left; width: 100px; height: 80px; border: none; } .smartH .title{ float: right; margin: 0 5px; width:90px; font-weight: bold; font-size: 13px; color: #000; line-height: 1.4; text-align: left; } .smartH .text{ float: right; margin: 5px 5px 0; width:90px; font-size: 12px; color: #000; line-height: 1.1; text-align: left; } .smartAd{ float:left; width:627px; overflow: hidden; } .smartH li{ position:relative; float:left; display: inline; height:80px; width:200px; padding:0 4px 0 5px; list-style-type: none; } .smartAd .paginate{ float:right } .smartAd i{ cursor:pointer; } </code></pre> <p>jQuery</p> <pre><code> $( function () { var posF = $(".smartH li.first").position(); var posL = $(".smartH li.last").position(); $("a#next").click( function () { $(".smartH li").stop().animate({ left: "-=209px", }, 500 ); if (posL.left == -627){ $(".smartH").css("background", "blue"); } return false; }); $("a#prev").click( function () { $(".smartH li").stop().animate({ left: "+=209px", }, 500 ); if (posF.left == 0){ $(".smartH").css("background", "green"); } return false; }); }); </code></pre> <p>html</p> <pre><code>&lt;div class="smartAd"&gt; &lt;ul class="smartH"&gt;&lt;!-- posit abs? --&gt; &lt;li class="first"&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/blinds.gif" alt="blinds" /&gt; &lt;p class="title"&gt;Call for a free quote today&lt;/p&gt; &lt;p class="text"&gt;Best value blinds in Lincolnshire!&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/coach.gif" alt="coach" /&gt; &lt;p class="title"&gt;Experience great days out&lt;/p&gt; &lt;p class="text"&gt;Great value coach trips&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/coffee.gif" alt="coffee" /&gt; &lt;p class="title"&gt;Need beans?&lt;/p&gt; &lt;p class="text"&gt;We have a great variety of beans at great prices&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/creditcard.gif" alt="credit card" /&gt; &lt;p class="title"&gt;Got bad credit?&lt;/p&gt; &lt;p class="text"&gt;We can help you boost your rating&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;li&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/mobility.gif" alt="mobility" /&gt; &lt;p class="title"&gt;Struggling to get around?&lt;/p&gt; &lt;p class="text"&gt;Great value scooters!&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;li class="last"&gt; &lt;a href="http://www.google.com" target="_blank"&gt; &lt;img src="http://advertising.co.uk/wallpaper/plumber.gif" alt="plumber" /&gt; &lt;p class="title"&gt;Got a leak?&lt;/p&gt; &lt;p class="text"&gt;Ring for reliable and friendly plumbers&lt;/p&gt; &lt;/a&gt; &lt;/li&gt; &lt;/ul&gt;&lt;!-- // ul.smartH --&gt; &lt;span class="paginate"&gt; &lt;a href="" class="icon" id="prev"&gt;Prev 1-&lt;/a&gt; &lt;a href="" class="icon" id="next"&gt;- Next 1&lt;/a&gt; &lt;/span&gt; &lt;/div&gt; </code></pre>

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.
