In this blog, I would like to add a code snippet for adding a new item in SharePoint Announcement list, using JavaScript Object Model. The Client Object Model must conclude with a call to ExecuteQuery() or ExecuteQueryAsync (ClientRequestSucceededEventHandler, ClientRequestFailedEventHandler).
Steps
  1. Open your SharePoint Site.
  2. Edit the SharePoint page and add a Content Editor WebPart .
  3. Add the following JavaScript code into CEWP.
  4. Save the page and hit F5.
Code snippet
  1. $(document).ready(function{
  3. createListItem();
  4. });
  6. function createListItem() {
  8. var clientContext = new SP.ClientContext(https://gowtham.sharepoint.com/tutorials");
  9. var oList = clientContext.get_web().get_lists().getByTitle('Announcements');
  10. this.oListItem = oList.getItemById(7);
  12. oListItem.deleteObject();
  14. clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
  15. }
  18. function onQuerySucceeded() {
  20. alert('Item created sucessfully: ' + oListItem.get_id());
  21. }
  23. function onQueryFailed(sender, args) {
  25. alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
  26. }
Thanks for reading my blog.
