When I look at the url at a given announcement list on e.g. a fresh team site, it is something like:


What I am trying is to link to a specific item in the list. Via SPServices I get the ID of the item easily - what I can't find is the ListId. I tried the GetList - operation but the "ID" which is given in that url is not the one I am looking for.

At which place is this ListId exposed?

EDIT: To make it more clear what I am coping with: The items in the announcement list all open with the URL I have provided above. What I can't find so far is the "ListId" value, in my actual case it is "{B3352...}". I already tried to get this ListId via SPServices GetList-operation but the value of the attribute "ID" from the returning XML shows a different ID {622C14...}. I looked at all the XML output and there is no value like the one I am looking for "{B3352...}" though I used the same code as already mentioned by yaron.

I found an error on my first approach and finally got the solution:

Unfortunately I didn't pass the webURL parameter on the GetListId function. So my result was nonesense.

The actual solution where to get the ListId from, I used the GetList-operation and parse for the Name-attribute:

var listId = $(xData.responseXML).find("List").attr("Name");

To add more detail to my overall topic, here is my final approach:

Final link structure


  • ListId - as mentioned above
  • ID - ID of the announcement item, got it through GetListItems $(this).attr("ows_ID")

Open Announcement in modal window

As users expect announcements to open in modal windows I added the following click event to my link element

onclick='NewItem2(event,this.href);return false;'

You can get List GUID by following this link


<script type="text/javascript" src="../ICTLibrary/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="../ICTLibrary/jquery.SPServices-0.5.4.min.js"></script> 

<script type="text/javascript">
$("document").ready(function() { 

function GetListId(listName) {
var id = "";
operation: "GetList",
listName: listName,
async: false,
completefunc: function (xData, Status) {
id = $(xData.responseXML).find("List").attr("ID");
return id;

var listid = GetListId("Plastic");
$("#listid").append("list not found");

<div id="listid" >Plastic list guid: </div>
  • I followed this example before, but neither the attribute "ID" nor any other one has the "ListId" value I am looking for.
