    <p>I need to make a slider.</p> <p>I have content (which should shift horizontally) and two buttons - "right" and "left". </p> <p>If you press the button and hold it, the content starts to move (in the appropriate direction). If you not hold the button, then the movement stops. This behavior copies the behavior of a usual window scrollbar.</p> <p>I wrote some code:</p> <pre><code>var animateTime = 1, offsetStep = 5; //event handling for buttons "left", "right" $('.bttR, .bttL') .mousedown(function() { scrollContent.data('loop', true).loopingAnimation($(this)); }) .bind("mouseup mouseout", function(){ scrollContent.data('loop', false); }); $.fn.loopingAnimation = function(el){ if(this.data('loop') == true){ var leftOffsetStr; leftOffsetInt = parseInt(this.css('marginLeft').slice(0, -2)); if(el.attr('class') == 'bttR') leftOffsetStr = (leftOffsetInt - offsetStep).toString() + 'px'; else if(el.attr('class') == 'bttL') leftOffsetStr = (leftOffsetInt + offsetStep).toString() + 'px'; this.animate({marginLeft: leftOffsetStr}, animateTime, function(){ $(this).loopingAnimation(el); }) } return this; } </code></pre> <p>But it does have a few things that I do not like:</p> <ol> <li>It always calls the function animation (<code>loopingAnimation</code>) - I think that this is an extra load (not good).</li> <li>When moving content he "twitches and trembling" - (it's not pretty).</li> </ol> <p>How can I solve this problem more <strong>elegantly</strong> and without the drawbacks of my code?</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.
