javascript - 使用 REST API 在主机 Web 列表中插入记录的 SharePoint 应用程序

Question

我编写了以下代码来将记录插入到主机站点中包含的列表中。

var projectItems = [
    { Title: "SharePoint", ProjectDescription: "SharePoint 2013", ProjectManager: "Test0" },
    { Title: "Lync", ProjectDescription: "Lync 2013", ProjectManager: "Test1" },
    { Title: "Exchange", ProjectDescription: "Exchange 2013", ProjectManager: "Test2" }
];

function insertListItems(items) {
    for (var item in items) {

        var inputData = new Object();
        var type = new Object();
        type.type = getListItemType(listName);
        inputData.__metadata = type;
        for (var prop in items[item]) {
            inputData[prop] = items[item][prop];
        }

        console.log(JSON.stringify(inputData));
        console.log(url);

        var obj = {
            url: url,
            type: "POST",
            contentType: "application/json; odata=verbose",
            data: JSON.stringify(inputData),
            headers: { "Accept": "application/json; odata=verbose", "X-RequestDigest": $("#__REQUESTDIGEST").val() },
            success: function (successData) { console.log("insert successful"); },
            error: function (errorData) { console.log("insert failed") }
        };

        if (parent) {
            var exec = new SP.RequestExecutor(appWebUrl);
            exec.executeAsync(obj);

        } else {
            $.ajax(obj);
        }            
    }
}

insertListItems(projectItems);

当我运行它时，它会打印

{"__metadata":{"type":"SP.Data.ProjectsListItem"},"标题":"SharePoint","ProjectDescription":"SharePoint 2013","ProjectManager":"Test0"}

http://app-e9f4c136adfd88.abhiapps.com/SPAppHelper/_api/SP.AppContextSite(@target)/web/lists/getbytitle ('项目')/items?@target=' http://dev.abhi.com '

{"__metadata":{"type":"SP.Data.ProjectsListItem"},"标题":"Lync","ProjectDescription":"Lync 2013","ProjectManager":"Test1"}

http://app-e9f4c136adfd88.abhiapps.com/SPAppHelper/_api/SP.AppContextSite(@target)/web/lists/getbytitle ('项目')/items?@target=' http://dev.abhi.com '

{"__metadata":{"type":"SP.Data.ProjectsListItem"},"标题":"Exchange","ProjectDescription":"Exchange 2013","ProjectManager":"Test2"}

http://app-e9f4c136adfd88.abhiapps.com/SPAppHelper/_api/SP.AppContextSite(@target)/web/lists/getbytitle ('项目')/items?@target=' http://dev.abhi.com '

插入成功 插入成功 插入成功

我对该源代码有多个问题

1. 实际上没有插入任何记录。但不会引发任何错误。

2. 如何确保在我的 main 方法中...仅当所有 3 条记录都已成功插入时才执行 insertListItems 方法之后的代码。目前，由于 JavaScript 的异步特性，即使在插入任何内容之前，流程也会向前推进。

3. 我在 google 上搜索了选项 2，发现 jquery 有一个 promise 和延迟对象模式，但似乎 SP.RequestExecutor.executeAsync 不遵循该模式，并在“done”方法上抛出错误，表示不支持此类方法.

这就是我的列表的样子

将您的 obj 替换为:

        ....
        method: "POST",
        body: JSON.stringify(inputData),
        headers: {
                 "Accept": "application/json;odata=verbose",
                 "content-type": "application/json;odata=verbose",
                 "X-RequestDigest": $("#__REQUESTDIGEST").val()
             }
        ....
        ....
