<script>
var siteUrl = 'https://team.abc.com/sites/XYZ/';
function createListItem() {
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('Test Projects');
var itemCreateInfo = new SP.ListItemCreationInformation();
this.oListItem = oList.addItem(itemCreateInfo);
oListItem.set_item("Project_ID_x003a_ID","490"); //lookup
oListItem.set_item("Time_x002d_ProjectType","NA"); //choice
oListItem.set_item("SiteURL","https://team.abc.com/sites/XYZ/490/pages/home.aspx");//text
oListItem.set_item("ProjectManager","shristy.priyadarshi@abc.com");//person and group
oListItem.update();
clientContext.load(oListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}
function onQuerySucceeded() {
alert('Item created: ' + oListItem.get_id());
}
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}
</script>
</head>
