    Reset increments for each list

    Greetings,

    So i have this code which is doing what i sorta want but not really. Right now it just looks for all li elements of a ordered list inside a div with id content. it prepends a span tag with a number that increments from 1 yadda yadda. Ok, now the problem. When there are additional ordered lists, it should reset, right now it just continues off where the last list ends. See example below:

    JS:
    $('#content ol li').each(function(j){
    var bulletNum = j+1;
    $(this).prepend('<span class="bullet-'+bulletNum+'"></span>');
    });


    Outputted html:
    <div id="content">
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    <ol>
    <li><span class="bullet-4">what am</span</li>
    <li><span class="bullet-5">i doing</span</li>
    <li><span class="bullet-6">wrong?</span</li>
    </ol>
    </div>

    What should happen:
    <div id="content">
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    </div>

    I know this is probably easy but what am I doing wrong here?

    Strange code, what language is that?
    Here's all I could decipher, the code you may be looking for is at end

    HTML Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <HTML>
    <HEAD><TITLE>Th5-59pm50</TITLE>
    <META http-equiv=Content-Type content="text/html; charset=UTF-8">
    <STYLE type=text/CSS>
    * {margin:20; padding:0;}
    
    </STYLE>
    
    
    <META content="MSHTML 6.00.2900.2963" name=GENERATOR></HEAD>
    <BODY scroll="auto">
    JS:
    $('#content ol li').each(function(j){
    var bulletNum = j+1;
    $(this).prepend('<span class="bullet-'+bulletNum+'"></span>');
    });
    
    
    Outputted html:
    <div id="xcontent">
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    <ol>
    <li><span class="bullet-4">what am</span</li>
    <li><span class="bullet-5">i doing</span</li>
    <li><span class="bullet-6">wrong?</span</li>
    </ol>
    </div>
    
    What should happen:
    <div id="content">
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    <ol>
    <li><span class="bullet-1">what am</span</li>
    <li><span class="bullet-2">i doing</span</li>
    <li><span class="bullet-3">wrong?</span</li>
    </ol>
    </div>
    <SCRIPT type="text/javascript">
    var co=document.getElementById('content').getElementsByTagName('ol');
     for(i=0;i<co.length;i++){   var l=co[i].getElementsByTagName('li');
                      for(j=0;j<l.length;j++){l[j].innerHTML='<span class="bullet-'+(j+1)+'" title="class=bullet-'+(j+1)+'">'+(j+1)+'</span>'}
     }
    </SCRIPT>
    
    
    </BODY></HTML>

    one things though. innerHTML is replacing all the content inside the li element. I just want the span tags to be prepended to the li element.

    <li><span class="bullet-1"></span> lorem ipsum dolor sit</li>

    and not

    <li><span class="bullet-1"></span></li>

    Here's another way if you already have spans inside the <li>

    HTML Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <HTML>
    <HEAD><TITLE>Th5-59pm50</TITLE>
    <META http-equiv=Content-Type content="text/html; charset=UTF-8">
    <STYLE type=text/CSS>
    * {margin:20; padding:0;}
    .bullet-1{color:green}
    .bullet-2{color:red}
    .bullet-3{color:blue}
    .bullet-4{color:#FF9900}
    
    </STYLE>
    
    
    <META content="MSHTML 6.00.2900.2963" name=GENERATOR></HEAD>
    <BODY scroll="auto">
    <div id="content">
    <ol>
    <li><span>how</span></li>
    <li><span>about</span></li>
    <li><span>this</span></li>
    </ol>
    <ol>
    <li><span>then?</span></li>
    <li><span>yes</span></li>
    <li><span>no?</span></li>
    </ol>
    <ol>
    <li><span>I knew</span></li>
    <li><span class="bullet-4">you'd be</span></li>
    <li><span>back</span></li>
    <li><span>for this</span></li>
    </ol>
    </div>
    <SCRIPT type="text/javascript">
    var co=document.getElementById('content').getElementsByTagName('ol');
     for(i=0;i<co.length;i++){   var l=co[i].getElementsByTagName('li');
                      for(j=0;j<l.length;j++){ l[j].getElementsByTagName('span')[0].className='bullet-'+(j+1)+'';
    
    	}
     }
    </SCRIPT>
    
    
    </BODY></HTML>
