如何使用javascript更新所选的SharePoint项目列表项目，

嗨，这工作正常按钮点击;它循环视图中选定的项目，提醒&调用updateListItem功能如何使用javascript更新所选的SharePoint项目列表项目，

function ViewSelectedItems(){ 
var selectedItems = SP.ListOperation.Selection.getSelectedItems();for (var i = 0; i < selectedItems.length; i++) { alert("Item with Id = " + selectedItems[i].id+ " is selected"); updateListItem(selectedItems[i].id)} 
       window.location.href = window.location.href; 
}

的updateListItem报告onQuerySucceeded但该字段值没有被设置为新的id的值。请有任何想法吗？

function updateListItem(passedid) { 

var siteUrl = '/supportdepts/hr/'; 

var newval = 999; 

    var clientContext = new SP.ClientContext(siteUrl); 
    var oList = clientContext.get_web().get_lists().getByTitle('Staffing Control Panel Request'); 
    this.oListItem = oList.getItemById(passedid); 
    oListItem.set_item("RefNumber", newval); 
    oListItem.update(); 
    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), 


    Function.createDelegate(this, this.onQueryFailed)); 
} 

function onQuerySucceeded() { 
    alert('Item updated!'); 
} 

function onQueryFailed(sender, args) { 
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace()); 
}
