Why doesn't slide show jquery work?

Question

JavaScript

Hello.

Is there a code for the slideshow?

function slideSwitch() {<br/>
 var $active = $('#slideshow DIV.active');<br/>
<br/>
if ( $active.length == 0 ) $active = $('#slideshow DIV:last');<br/>
<br/>
var $next = $active.next().length ? $active.next()<br/>
 : $('#slideshow DIV:first');<br/>
<br/>
$active.addClass('last-active');<br/>
<br/>
$next.css({opacity: 0.0})<br/>
 .addClass('active')<br/>
 .animate({opacity: 1.0}, 1000, function() {<br/>
 $active.removeClass('active last-active');<br/>
 });<br/>
}<br/>
<br/>
$(function() {<br/>
 setInterval( &quot;slideSwitch()&quot;, 5000 );<br/>
});<br/>

And inserting the slideshow itself

&lt;-div id=&quot;slideshow&quot; align=&quot;center&quot;&gt;<br/>
 &lt;-div class=&quot;active&quot;&gt;<br/>
 &lt;-a href=&quot;/test1.html&quot;&gt;&lt;-img src=&quot;/images/images1.jpg&quot; alt=&quot;&quot; class=&quot;active&quot; /&gt;&lt;-/a&gt;<br/>
 &lt;-/div&gt;<br/>
 &lt;-div&gt;<br/>
 &lt;-a href=&quot;/test2.html&quot;&gt;&lt;-img src=&quot;/images/images2.jpg&quot; alt=&quot;&quot; /&gt;&lt;-/a&gt;<br/>
 &lt;-/div&gt;<br/>
&lt;-/div&gt;<br/>

The problem is that the jquery-1.6.2.min.js engine itself (but the file is simply called jquery.js) is already included. But the code doesn't work that way. But if you insert before the script code of the slideshow

<-script type="text/javascript" src="/js/jquery-1.6.2.min.js"><-/script>"

The slideshow starts working.

The question is why the slideshow does not work if you do not insert a jquery connection before the slideshow script?

PS I checked that the jquery file in the engine and the jquery-1.6.2.min.js file downloaded from the jquery site are identical

Answer 1

Is this jquery.js connected by any chance after the Slide Show?
Give an example page or copy errors from the console if any.
PS cache the elements

setInterval( "slideSwitch()", 5000 ); // и никогда так не делайте 
setInterval(slideSwitch, 5000 ); // вот так намного лучше

Answer 2

jquery connects after, error in Web Console
$active is null

Answer 3

In general, I localized the problem to the point that jquery and mootools are not compatible
