Question

在$ scope中，我有一个名为 thisProject 的对象，它在控制台中记录如下：

[    0: {
       [functions]: ,
       __metadata: { },
       AttachmentFiles: { },
       Attachments: false,
       AuthorId: 9,
       CloseDate: null,
       ContentType: { },
       ContentTypeId: "0x010087886FAC81322548A66F903FF786897C",
       Created: "2014-05-06T21:24:35Z",
       Division: "Information Technology",
       Division_ID: "21",
       Due_Date: "2014-05-12T07:00:00Z",
       EditorId: 9,
       FieldValuesAsHtml: { },
       FieldValuesAsText: { },
       FieldValuesForEdit: { },
       File: { },
       FileSystemObjectType: 0,
       FirstUniqueAncestorSecurableObject: { },
       Folder: { },
       GUID: "291f7307-b134-47e6-b13e-09fd86fe31ce",
       ID: 6,
       Id: 6,
       Imported_From_Project: false,
       Modified: "2014-05-06T21:24:35Z",
       OData__UIVersionString: "1.0",
       ParentList: { },
       Project_Lead: "Eyre, Jane",
       Priority: "High: Time Sensitive",
       Priority_Group: "High",
       Priority_ID: "3",
       Project_GUID: "1069",
       Requestor: "Plath, Sylvia",
       RoleAssignments: { },
       **Site_ID: "8",**
       Status: "In Progress",
       Status_ID: "2",
       Title: "Design Website Graphics",
       Website: "SharePoint"    },
    length: 1 ]

我在$ scope中还有一个名为网站的对象，目前有13个节点，其中相关的对象记录为：

{
   [functions]: ,
   __metadata: { },
   ID: 8,
   Id: 8,
   Title: "SharePoint"
}

所以我想显示网站的名称（在SharePoint中称为标题）而不是ID，所以我将此功能添加到控制器：

$scope.getWebsite = function(id){
    for(w=0; w<$scope.websites.length; w++){
        if($scope.website[w].ID == id){
        return $scope.website[w].Title;
        } // end if
    } // end for
};

对于AgularJS来说还是一个新手，对我来说非常有意义，我会找到匹配并将网站的名称分配给$ scope.getWebsite，这意味着当我把它放在模板中时它会正确显示：

<p>{{getWebsite(thisProject[0].Site_ID)}}</p>

控制台充满了

的13条错误消息（每个网站一条）

无法插值{{getWebsite(thisProject[0].Site_ID}}。

Answer 1

看起来你在getWebsite内有一些拼写错误。在......

if($scope.website[w].ID == id){
return $scope.website[w].Title;

website属性应为复数。

Can＆＃39; t Interpolate {{getWebsite（thisProject [0] .Site_ID}}是什么意思？
