javascript - 无法获取未定义或空引用的属性“customXmlParts”

Question

我正在从 Word365 Web 加载项单击自定义功能区栏按钮执行功能。由于此过程涉及多个对话框，因此我ExecuteFunction在清单文件中使用操作类型“”来单击功能区栏按钮。

单击功能区栏按钮“工作流”后，应打开“附加”对话框。该对话框中有一个名为“附加”的按钮。它应该打开一个服务器浏览对话框，并且选择的服务器文件将返回一个 json，我需要将其转换为 xml 并存储在 中document.CustomXmlParts，因为它应该保存为文档特定值。

我还没有开始服务器浏览部分。我正在尝试在其中存储一些示例 xmldocument.CustomXmlParts作为测试尝试。但我无法访问Office.context.document.CustomXmlParts，它给出了错误“ Unable to get property 'customXmlParts' of undefined or null reference”。但是当我尝试Office.context.document.CustomXmlParts在 FunctionFile.js 中访问时，我可以保存 xml 内容并成功检索它。

请帮我弄清楚到底是什么问题。

函数文件.js

// The initialize function must be run each time a new page is loaded.
(function () {
    Office.initialize = function (reason) {
        // If you need to initialize something you can do so here.
    };
})();

var ShowAttachXMLDialog = function (event) {
    try {
        var dialogUrl = 'https://' + location.host + '/App/Dialogs/DlgAttach/DlgAttachXML.html';

        Office.context.ui.displayDialogAsync(dialogUrl, { width: 60, height: 50, requireHTTPS: true }, function (asyncResult) {
            if (asyncResult.status !== Office.AsyncResultStatus.Succeeded) {
        

    showAlert('editDlg', asyncResult.error.message);
        } else {
            _dialog = asyncResult.value;
        }
    });

    } catch (e) {
        showAlert(e.location, e.message);
    }

}

DlgAttachXML.js 文件

(function () {

    Office.initialize = function (reason) {
        // If you need to initialize something you can do so here.
        var doc = Office.context.document;

        $(document).ready(function () {

            thisDocument = document;
            document.getElementById("attach-button").onclick = selectXMLFromServer;
        });
    };

})();

var selectXMLFromServer = function (event) {
    //that sample xml I am trying to insert.
    var xmlString = "<Reviewers xmlns='http://schemas.contoso.com/review/1.0'><Reviewer>Juan</Reviewer><Reviewer>Hong</Reviewer><Reviewer>Sally</Reviewer></Reviewers>";

    //Error occurs in here
    Office.context.document.customXmlParts.addAsync(xmlString,
        (asyncResult) => {
            Office.context.document.settings.set('AttachedXML', asyncResult.value.id);
            Office.context.document.settings.saveAsync();
        }
    );
    event.completed();
}

先感谢您。
