Question

我一直在阅读在排队多个项目以便在SP列表中处理之后只执行一个查询。

我有以下代码，其中有一个按钮，可以将一堆记录加载到Excel电子表格中的空SP列表中。如果我在每个item.update之后执行executequery就行了......但是我觉得应该有更好的方法..我可以排队数组中的项目并一次发送所有项目。我看到了如何使用exisitng列表项来做到这一点的示例......但我还没有看到使用新项目的方法。我能够删除项目...将它们全部缓存并执行一次执行查询以删除所有项目......这显然比每个项目的eq快1000倍。所以希望通过添加新项目来做同样的事情。谢谢你的任何想法。

            ExcelWorksheet workSheet = package.Workbook.Worksheets[GlobalVars.ssApplicantsTab];

            //Start iterating through ss

                     i <= workSheet.Dimension.End.Row;

                string van = workSheet.Cells[i, 1].Value.ToString();
                string appID = workSheet.Cells[i, 2].Value.ToString();
                string name = workSheet.Cells[i, 3].Value.ToString();
                string email = workSheet.Cells[i, 4].Value.ToString();

                logThis(van + "-" + appID + "-" + name + "-" + email + " queued for processing.");

                //Push an item to the stack:
                oListItem["AppID"] = appID;
                oListItem["ApplicantName"] = name;
                oListItem["VAN"] = van;
                oListItem["ApplicantEmailAddress"] = email;
                oListItem.Update();
                //context.ExecuteQuery();  ***with ExecuteQuery here it works

            }
            //After all items pushed onto stack...call ExQuery to apply            
            logThis("Starting ExecuteQuery to process queued list items...");
            context.ExecuteQuery();   //Here it gives me only last name in spreadsheet         
            logThis("FINISHED ADDING INDIVIDUAL APPLICANTS");
        }

弄清楚了。我把ListItem放在了错误的地方。需要它在我的for循环中而不是在它之外。下面的工作代码：

componentDidMount() {
    dbx.filesListFolder({ path: '/my-photos' })
    .then(res => res.entries.map(file => file.path_display))
    .then(res => {
        let photoArray = res.map(path => dbx.filesGetTemporaryLink({ path: path }));
        console.log(photoArray);
    });
}

SP客户端对象模型 - 仅使用一个ExecuteQuery将多个新项添加到列表中
