Office Javascript API:MS Project标识父任务ID和子任务ID [英] Office Javascript API: MS Project identify parent task id and sub task id

问题描述

我正在构建MS Project Web加载项.使用下面的函数作为其他函数的基础，我可以检索task, id and resource name.

// Get the maximum task index, and then get the task GUIDs.
async getTasks(guids: string[]): Promise<any[]> {
    return await Promise.all(
        guids.map(async guid => await this.getTask(guid))
    );
}

async getTaskGuids(maxIndex: number): Promise<string[]> {
    const guids = [];
    for (let i = 0; i <= maxIndex; i++) {
        guids.push(await this.getTaskGuid(i));
    }
    return guids;
}

请参见下面的屏幕截图，其中包含缩进/子任务.

现在，我需要确定任务是子任务还是缩进任务.识别此问题的最佳方法是什么.任何示例代码都非常有帮助.请帮助

解决方案

使用getTaskFieldAsync方法获取任务的特定字段值.例如，它返回概述级别任务(例如1、2、3等):

_projDoc.getTaskFieldAsync(taskGuid, Office.ProjectTaskFields.OutlineLevel,
    function (asyncResult) {
        if (asyncResult.status == Office.AsyncResultStatus.Succeeded) {
            text.value = text.value + "Outline Level: "
                + asyncResult.value.fieldValue + "\n";
        }
        else {
            logMethodError("getTaskFieldAsync", asyncResult.error.name,
                           asyncResult.error.message);
        }
    }
);

另请参阅任务摘要属性，用于确定任务是否为摘要. OutlineChildren 集合也可能有用以及 OutlineParent 属性.

有关参考，请参见 解决方案

Use the getTaskFieldAsync method to get specific field values for a task. For example this returns the Outline Level of a task (e.g. 1, 2, 3, etc.):

_projDoc.getTaskFieldAsync(taskGuid, Office.ProjectTaskFields.OutlineLevel,
    function (asyncResult) {
        if (asyncResult.status == Office.AsyncResultStatus.Succeeded) {
            text.value = text.value + "Outline Level: "
                + asyncResult.value.fieldValue + "\n";
        }
        else {
            logMethodError("getTaskFieldAsync", asyncResult.error.name,
                           asyncResult.error.message);
        }
    }
);

Also see the task Summary property to determine if a task is a summary or not. The OutlineChildren collection might also be useful as well as the OutlineParent property.
