I have a list with a lot of items in it I need to know the list item count the following is my code:

var sListId = SP.ListOperation.Selection.getSelectedList();
var oWeb = item_clientContext.get_web();
var oList = oWeb.get_lists().getById(sListId);
var count = ???

How can I determine the count of items I have? I tried get_count() but did not work.

Since you're using the JavaScript CSOM you need to fetch the properties asynchronously. Your code should look something like this:

var oList;
function theFunction() {
    var sListId = SP.ListOperation.Selection.getSelectedList();
    var oWeb = item_clientContext.get_web();
    oList = oWeb.get_lists().getById(sListId);

    // .load() tells CSOM to load the properties of this object
    // multiple .load()s can be stacked

    // now start the asynchronous call and perform all commands
    item_clientContext.executeQueryAsync(onSuccess, onFail);
    // method will exit here and onSuccess or OnFail will be called asynchronously
function onSuccess(sender, args) {
    alert('No of rows: ' + oList.get_itemCount());
function onFail(sender, args) {
    alert('Request failed.\n' + args.get_message() + '\n' + args.get_stackTrace());

oList.ItemCount has your property.

  • The error is that it is telling me that the list is not initialized. so i tried the following before executing var oList = oWeb.get_lists().getById(sListId); item_clientContext.load(oList); item_clientContext.executeQueryAsync(); var count = oList.get_itemCount();

  • @IanCian: So oList is null? Did you try var count = oList.ItemCount;?
