    <p>I need to start, stop and restart a lateral animation with Javascript, with some search i found that Jquery <code>animate()</code> needs a plugin to do start-stop-restart, but i won't to use a plugin for do this (not waist your time to ask "why not?").</p> <p>So, I asked me: "why you not use <code>setInterval()</code> to do this lateral animation and stop it with <code>clearInterval()</code>?</p> <p>This is my code, is correct or is a crazy work for browser? I need to build a "efficent" (in terms of browser works) script but, I'm not the best about this. Have mercy plz.</p> <pre><code>window.newsflash.interval = setInterval(function() { if(liWidthTot + $('.fn_container ul').css("left") &lt;= 0) $('.fn_container ul').css('left', containerWidth); $('.fn_container ul').css("left", "-=1px"); },10); //handler $("#xml").on({ mouseenter: function(){ clearInterval(window.newsflash.interval); }, mouseleave: function(){ window.newsflash.interval = setInterval(function() { if($('.fn_container ul').css("left") - liWidthTot &lt;= 0) $('.fn_container ul').css('left', containerWidth); $('.fn_container ul').css("left", "-=1px"); },10); } }); </code></pre> <p>its only a peace of my Js code... I not need to know how to... but if use setInterval() is a bad idea.</p> <p>----- edit ----</p> <p>Now:</p> <pre><code>var newsList = document.getElementById("newsList"); window.newsflash.interval = setInterval(function() { if(liWidthTot + parseInt(newsList.style.left) &lt;= 0) newsList.style.left = containerWidth +"px"; ewsList.style.left = (parseInt(newsList.style.left) -1) + "px"; },10); //handler $("#xml").on({ mouseenter: function(){ clearInterval(window.newsflash.interval); }, mouseleave: function(){ window.newsflash.interval = setInterval(function() { if(liWidthTot + parseInt(newsList.style.left) &lt;= 0) newsList.style.left = containerWidth +"px"; newsList.style.left = (parseInt(newsList.style.left) -1) + "px"; },10); } }) </code></pre> <p>Thx mates.</p>

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.
