无法在Sharepoint 2013列表中创建新项目

我正尝试使用淘汰赛js和REST将项目保存到SharePoint列表中。在我的Ajax POST中，我使用了ko.toJSON。我尝试使用JSON.stringify，但我无法看到SharePoint列表中的条目。我可能传递了错误的参数值。在此先感谢。无法在Sharepoint 2013列表中创建新项目

我的HTML：

<link rel="Stylesheet" href="/css/default.css" /> 

<script type="text/javascript" src="/js/knockout-3.4.2.js"></script> 
<script type="text/javascript" src="/js/jquery-3.2.1.min.js"></script> 

<script type="text/javascript" src="/js/o.min.js"></script> 

<form id="form1" runat="server"> 
<div class="style1"> 
<div class="codeRunner"><br/> 


<h3>Tasks</h3> 


<form data-bind="submit: addTask"> 
    Add task: <input data-bind="value: newTaskText" placeholder="What needs to be done?" /> 
    <button type="submit">Add</button> 
</form> 

<ul data-bind="foreach: tasks, visible: tasks().length > 0"> 
    <li> 
     <input type="checkbox" data-bind="checked: isDone" /> 
     <input data-bind="value: title, disable: isDone" /> 
     <a href="#" data-bind="click: $parent.removeTask">Delete</a> 
    </li> 
</ul> 

You have <b data-bind="text: incompleteTasks().length">&nbsp;</b> incomplete task(s) 
<span data-bind="visible: incompleteTasks().length == 0"> - it's water time!</span> 

<br/> 
<button data-bind="click: save">Save</button> 

</div> 
</div> 
</form>

我的JS：

<script type="text/javascript"> 

var sharepointBaseUrl = "/trp/"; 
var sharepointTaskListUrl = sharepointBaseUrl + "_api/lists/getbytitle('Test2')"; 



function Task(sharepointItem) { 
    var self = this; 

    self.id = sharepointItem.ID; 

    self.title = ko.observable(sharepointItem.Title); 
    self.isDone = ko.observable(sharepointItem.IsDone); 
} 



function TaskListViewModel() { 
    // Data 
    var self = this; 
    self.tasks = ko.observableArray([]); 
    self.newTaskText = ko.observable(); 
    self.incompleteTasks = ko.computed(function() { return ko.utils.arrayFilter(self.tasks(), function(task) { return !task.isDone() }); }); 

    // Operations 
    self.addTask = function() { 
     self.tasks.push(new Task({ Title: this.newTaskText() })); 
     self.newTaskText(""); 
     var itemType="SP.Data.Test2ListItem"; 
     var addedItems=ko.toJSON({ 
      __metadata: itemType, 
      'Title': self.newTaskText() 
     }); 

     $.ajax({ 
      url: sharepointTaskListUrl + "/items", 
      type: "POST", 
      headers: { 
       "accept": "application/json;odata=verbose", 
       "X-RequestDigest": $("#__REQUESTDIGEST").val(), 
       "content-Type": "application/json;odata=verbose" 
      }, 
      data: addedItems, 
      success: function (data) { 
       console.log(data); 
      }, 
      error: function (error) { 
       alert(JSON.stringify(error)); 
      } 
     }); 


    }; 
    self.removeTask = function(task) { self.tasks.remove(task) }; 



    //load from SP List 
    $.ajax({ 
      url: sharepointTaskListUrl + "/items", 
      method: "GET", 
      headers: { "Accept": "application/json; odata=verbose" }, 
      success: function (data) 
        { 
         var items = data.d.results; 
         items.forEach(function(item) { self.tasks.push(new Task(item)); }); 
        }, 
      error: function (data) { alert("ERROR: " + data) } 
    }); 




} 

ko.applyBindings(new TaskListViewModel()); 


</script>

在你的源代码：

self.addTask = function() { 
     self.tasks.push(new Task({ Title: this.newTaskText() })); 
     self.newTaskText(""); (1) 
     var itemType="SP.Data.Test2ListItem"; 
     var addedItems=ko.toJSON({ 
      __metadata: itemType, 
      'Title': self.newTaskText() (2)

在（1）你正在清理newTaskText()。在（2）中，你将它添加到你的json中。

你可以改变这种解决方案：

self.addTask = function() { 
     var task = new Task({ Title: this.newTaskText() }); 
     self.tasks.push(task); 
     self.newTaskText(""); 
     var itemType="SP.Data.Test2ListItem"; 
     var addedItems=ko.toJSON({ 
      __metadata: itemType, 
      'Title': task.title()

这里我定义了一个task变量，并从中获得冠军。
