I want to sort my <ul id="vlist"> li (via onclick)
For example if Unit is selected from the ddmenu ID order the ul vlist ID li list based on that span class.

<div class="widgetbox">
                            <div class="title"><h3> Fleet Vehicles</h3></div>
                            <div class="widgetoptions" style="height:33px; font-weight:bold">
                                <div style=" float:left; display:inline-block;">
                                <ul id="ddmenu" class="photosharing_menu">
                                    <li class="marginleft5 dropdown" id="actions">
                                        <a class="dropdown_label" style=" padding-right:30px" href="#actions">
                                        Sort By
                                        <span class="arrow"></span>

don't need jquery

<script>
function sortUnorderedList(ul, sortDescending) {
  if(typeof ul == "string")
    ul = document.getElementById(ul);

  // Idiot-proof, remove if you want
  if(!ul) {
    alert("The UL object is null!");
    return;
  }

  // Get the list items and setup an array for sorting
  var lis = ul.getElementsByTagName("LI");
  var vals = [];

  // Populate the array
  for(var i = 0, l = lis.length; i < l; i++)
    vals.push(lis[i].innerHTML);

  // Sort it
  vals.sort();

  // Sometimes you gotta DESC
  if(sortDescending)
    vals.reverse();

  // Change the list on the page
  for(var i = 0, l = lis.length; i < l; i++)
    lis[i].innerHTML = vals[i];
}

Open in new window


example :

<ul id="listid">
  <li>two</li>
  <li>one</li>
  <li>bee</li>
  <li>test</li>
  <li>zeta</li>
  <li>five</li>
</ul>
<input type="Button" Text="sort" onClick="javascript:sortUnorderedList('listid')">

Thx for your responce.
However I have seen the example before.

Can you modify that exp to where you click on a link to sort based on a <span id> thats within the <li> tag.

the script works but the sorting criteria is the inner html itself (in this case the sorting order users the thumbs name, because thumbs are the first part of string inside <li> tag).
To choose a different criteria you shoud change code on  vals.sort() including a control function.

vals.sort(sortfunction)

function sortfunction(a, b){
//Compare innert html of "a" and "b" and then return -1, 0, or 1
}

Open in new window


The easiest way is to call thumbs with the same name of the <a href=""> title </a> so you don't have to create a sortfunction but just to assign images the same name of the article


(in this example you sort descending the  vlist accoring to thumb name)

<script>
function sortUnorderedList(ul, sortDescending) {
  if(typeof ul == "string")
    ul = document.getElementById(ul);

  // Idiot-proof, remove if you want
  if(!ul) {
    alert("The UL object is null!");
    return;
  }

  // Get the list items and setup an array for sorting
  var lis = ul.getElementsByTagName("LI");
  var vals = [];

  // Populate the array
  for(var i = 0, l = lis.length; i < l; i++)
    vals.push(lis[i].innerHTML);

  // Sort it
  vals.sort();

  // Sometimes you gotta DESC
  if(sortDescending)
    vals.reverse();

  // Change the list on the page
  for(var i = 0, l = lis.length; i < l; i++)
    lis[i].innerHTML = vals[i];
}
</script>
<div class="widgetbox">
