Javascript 无法使用JS OM将自定义web部件添加到页面

我正在尝试使用SharePoint 2010提供的新Javascipt OM添加一个自定义web部件（这是我自己编写的）。我的解决方案也在沙箱中运行

我已将其正确用于Content Editor Web部件（基于示例代码），但是，当我将Content Editor Web部件定义替换为用于我自己的Web部件的定义时，会出现以下错误：

---------------------------
Message from webpage
---------------------------
Request failed. The operation could not be completed because the Web Part is not on this page.
undefined
---------------------------
OK   
---------------------------

我测试过的东西：

我可以成功地将我的.webpart定义上载到web部件库，并且web部件可以正常工作

我可以成功地将web部件添加到我正在使用“上载web部件”功能以编程方式尝试添加它的页面中 这是我用来添加web部件的代码：

function addWebPart(serverRelativeUrl) {
//var webPartXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
//webPartXml = webPartXml + "<WebPart xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns=\"http://schemas.microsoft.com/WebPart/v2\">  <Title>Content Editor</Title>  <FrameType>Default</FrameType>  <Description>Allows authors to enter rich text content.</Description>  <IsIncluded>true</IsIncluded>  <ZoneID>Main</ZoneID>  <PartOrder>0</PartOrder>  <FrameState>Normal</FrameState>  <Height />  <Width />  <AllowRemove>true</AllowRemove>  <AllowZoneChange>true</AllowZoneChange>  <AllowMinimize>true</AllowMinimize>  <AllowConnect>true</AllowConnect>  <AllowEdit>true</AllowEdit>  <AllowHide>true</AllowHide>  <IsVisible>true</IsVisible>  <DetailLink />  <HelpLink />  <HelpMode>Modeless</HelpMode>  <Dir>Default</Dir>  <PartImageSmall />  <MissingAssembly>Cannot import this Web Part.</MissingAssembly>  <PartImageLarge>/_layouts/images/mscontl.gif</PartImageLarge>  <IsIncludedFilter />  <Assembly>Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>  <TypeName>Microsoft.SharePoint.WebPartPages.ContentEditorWebPart</TypeName>  <ContentLink xmlns=\"http://schemas.microsoft.com/WebPart/v2/ContentEditor\" />  <Content xmlns=\"http://schemas.microsoft.com/WebPart/v2/ContentEditor\" />  <PartStorage xmlns=\"http://schemas.microsoft.com/WebPart/v2/ContentEditor\" /></WebPart>";

clientContext = new SP.ClientContext.get_current();
var oFile = clientContext.get_web().getFileByServerRelativeUrl(serverRelativeUrl);

var limitedWebPartManager = oFile.getLimitedWebPartManager(SP.WebParts.PersonalizationScope.shared);

我不确定你是否修过这个，但我认为你有一个不必要的问题

clientContext.load（oWebPart）

就在executeQueryAsync之前

如果您使用的是Firebug/Fiddler/IE9工具栏，请查看网络流量，ClientQuery的发布结果中会显示一些有用的错误消息。

您是否曾经使用过该工具？我遇到了相同的错误消息。

limitedWebPartManager.addWebPart(oWebPart, 'Main', 0);

clientContext.load(oWebPart);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));}

function onQuerySucceeded() {

    alert('Web Part added: ' + oWebPart.get_title());
}
function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}
