如何使用J查詢自動滾動旋轉

Question

數字應自動旋轉。在完成一個循環後，應該從以前週期

$(function() { 
 
     var interval = setInterval(function() { 
 
     if ($("#div1").scrollTop() != $('#div1')[0].scrollHeight) { 
 
      $("#div1").scrollTop($("#div1").scrollTop() + 10); 
 
     } else { 
 
      clearInterval(interval); 
 
     } 
 
     }, 1000); 
 
});

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> 
 
<div id="div1" style="height:60px;width:100%;border:1px solid #ccc;overflow:auto">>

/array to store IDs of our tabs 
     var tabs = []; 
    //index for array 
    var ind = 0; 
    //store setInterval reference 
     var inter; 

    //change tab and highlight current tab title 
    function change(stringref){ 
    //hide the other tabs 
     jQuery('.tab:not(#' + stringref + ')').hide(); 
    //show proper tab, catch IE6 bug 
if (jQuery.browser.msie && jQuery.browser.version.substr(0,3) == "6.0") 
    jQuery('.tab#' + stringref).show(); 
else 
    jQuery('.tab#' + stringref).fadeIn(); 
//clear highlight from previous tab title 
jQuery('.htabs a:not(#' + stringref + 't)').removeClass('active'); 
//highlight currenttab title 
jQuery('.htabs a[href=#' + stringref + ']').addClass('active'); 
} 
    function next(){ 
    //call change to display next tab 
    change(tabs[ind++]); 
//if it's the last tab, clear the index 
if(ind >= tabs.length) 
    ind = 0; 
    } 
    jQuery(document).ready(function(){ 
//store all tabs in array 
jQuery(".tab").map(function(){ 
    tabs[ind++] = jQuery(this).attr("id"); 
}) 
//set index to next element to fade 
ind = 1; 
//initialize tabs, display the current tab 
jQuery(".tab:not(:first)").hide(); 
jQuery(".tab:first").show(); 
//highlight the current tab title 
jQuery('#' + tabs[0] + 't').addClass('active'); 
//handler for clicking on tabs 
jQuery(".htabs a").click(function(){ 

    //if tab is clicked, stop rotating 
    clearInterval(inter); 
    //store reference to clicked tab 
    stringref = jQuery(this).attr("href").split('#')[1]; 
    //display referenced tab 
    change(stringref); 
    return false; 
}); 
//start rotating tabs 
inter = setInterval("next()", 7500);
