Question

i try to add dynamic content to tabs and hide content if tab is empty

html code

<ul id="tabs">
    <li><a href="#" name="#tab1">One</a></li>
    <li><a href="#" name="#tab2">Two</a></li>
    <li><a href="#" name="#tab3">Three</a></li>
    <li><a href="#" name="#tab4">Four</a></li>
</ul>

<div id="content_tabs">
    <div id="tab1">content 1</div>
    <div id="tab2">content 2</div>
    <div id="tab3">content 3</div>
    <div id="tab4">content 4</div>
</div>

js code

function resetTabs(){
    jQuery("#content_tabs > div").hide(); //Hide all content
    jQuery("#tabs a").attr("id",""); //Reset id's      
}

var myUrl = window.location.href; //get URL
var myUrlTab = myUrl.substring(myUrl.indexOf("#")); // For mywebsite. com/tabs.html#tab2, myUrlTab = #tab2     
var myUrlTabName = myUrlTab.substring(0,4); // For the above example, myUrlTabName = #tab

jQuery(function(){
    jQuery("#content_tabs > div").hide(); // Initially hide all content
    jQuery("#tabs li:first a").attr("id","current"); // Activate first tab
    jQuery("#content_tabs > div:first").fadeIn(); // Show first tab content

    jQuery("#tabs a").on("click",function(e) {
        e.preventDefault();
        if (jQuery(this).attr("id") == "current"){ //detection for current tab
         return       
        }
        else{             
        resetTabs();
        jQuery(this).attr("id","current"); // Activate this
        jQuery(jQuery(this).attr('name')).fadeIn(); // Show content for current tab
        }
    });

    for (i = 1; i <= $("#tabs li").length; i++) {
      if (myUrlTab == myUrlTabName + i) {
          resetTabs();
          jQuery("a[name='"+myUrlTab+"']").attr("id","current"); // Activate url tab
          jQuery(myUrlTab).fadeIn(); // Show url tab content        
      }
    }
});

beauty css

#tabs {
  overflow: hidden;
  width: 100%;
  margin: 0;
  padding: 0;
  list-style: none;
}

#tabs li {
  float: left;
  margin: 0 -15px 0 0;
}

#tabs a {
  float: left;
  position: relative;
  padding: 0 40px;
  height: 0; 
  line-height: 30px;
  text-transform: uppercase;
  text-decoration: none;
  color: #fff;
  border-right: 30px solid transparent;
  border-bottom: 30px solid #3D3D3D;
  border-bottom-color: #777\9;
  opacity: .3;
  filter: alpha(opacity=30);      
}

#tabs a:hover,
#tabs a:focus {
  border-bottom-color: #2ac7e1;
  opacity: 1;
  filter: alpha(opacity=100);
}

#tabs a:focus {
  outline: 0;
}

#tabs #current {
  z-index: 3;
  border-bottom-color: #3d3d3d;
  opacity: 1;
  filter: alpha(opacity=100);     
}

Changes from your original fiddle:

• Removed contents of <div id="tab2">.
• Added the following.

$("#content_tabs > div:empty").each(function() {
    $("#tabs > li").eq($(this).index()).hide();
});

EDIT:

In response to your comment about blank space, I created this fiddle:
http://jsfiddle.net/tdf22/3/

In this one, I:

• added the following jQuery custom expression

$.expr[":"].emptyOrWhiteSpace = function(obj){
  var $this = $(obj);
  return ($.trim($this.html()) === "");
};

• and changed this line

  $(“#content_tabs > div:empty”).each(function() {

• to this

  $(“#content_tabs > div:emptyOrWhiteSpace”).each(function() {
