更新多 select 查找列 REST

Question

短版： 我需要帮助或更新多 select 查找列 REST 的示例。我一直无法添加或更新 multi-select 查找列。

详情

我想做什么： 使用 SPA 中更新的多个查找 ID 更新列表项。我想了解我应该寻找什么以及如何应用它。而且我假设添加一行是相同的。

我施加的限制： 这必须通过客户端代码来完成。我无法部署 wsp/binary 代码。 :( SP2010 我陷入了 jQuery 1.8.3 的黑暗时代，在 IE11 上以文档模式 IE=8 运行呈现站点。

什么有效： 所有不涉及多重查找的 CRUD。使用 ...ListName(ID)/MultiLookupCol 形状在单独的调用中使用多重查找进行读取。

我尝试或研究过的： 我相信我得到的最接近的是这个。但是， 错误请求错误仍然失败：处理请求流时出错。负载必须代表集合的有效数组格式。

所以我认为我的 multi 属性构建与 Charles Manson 一样不稳定。假设那是我的罪魁祸首，我不知道该如何解决。

使用

var itemProperties = {
    "__metadata": { "type": 'Microsoft.SharePoint.DataService.GroupsOfNumbersItem' },

停止了我得到的类型名称错误。更近了，但还没有。

var aIDs = [1, 3];
var itemProperties = {
    "__metadata": { "type": 'Microsoft.SharePoint.DataService.MyNumbersItem' },
    "ReferenceLookup": { "results": aIDs }
};
updateListItem(myWebUrl(), 
               "GroupsOfNumbers", 
               1, 
               itemProperties,
    function () {
        console.log('Success');
    },
    function (error) {
        console.log(JSON.stringify(error));
    }
);

我已阅读并尝试应用来自多个页面的信息，最相关的似乎是以下内容。

为了完整性，这里是我的更新函数。

function getListItemById(webUrl, listName, itemId, success, failure) {
    var url = webUrl + "/_vti_bin/Listdata.svc/" + listName + "(" + itemId + ") ";

    $.ajax({
        url: url,
        method: "GET",
        headers: { "Accept": "application/json; odata=verbose" },
        success: function (data) {
            success(data.d);
        },
        error: function (data) {
            if (debug == true) {
                console.log("getListItemById ID:" + itemId);
                if (data.responseJSON) {
                    console.dir("Data: " + data);
                }
            }
            if (data.responseJSON) {
                failure(data.responseJSON.error);
            } else {
                console.log("getListItemById No data returned for ID: " + itemId);
            }

        }
    });
}

function updateListItem(webUrl, listName, itemId, itemProperties, success, failure) {
    getListItemById(webUrl, listName, itemId, function (item) {

        $.ajax({
            type: 'POST',
            url: item.__metadata.uri,
            contentType: 'application/json',
            processData: false,
            headers: {
                "Accept": "application/json;odata=verbose",
                "X-HTTP-Method": "MERGE",
                "If-Match": item.__metadata.etag
            },
            data: Sys.Serialization.JavaScriptSerializer.serialize(itemProperties),
            success: function (data) {
                success(data);
            },
            error: function (data) {
                failure(data);
            }
        });

    },
    function (error) {
        failure(error);
    });

}

Answer 1

使用 REST 将选择添加到多值查找字段

这是您的数据负载的必要格式：

var data = JSON.stringify({
    MultiLookupColumnName:[
        { 
            __metadata: { 
                uri: "http://yoursiteurl/_vti_bin/ListData.svc/LookupListName(1)"
            }
        },
         { 
            __metadata: { 
                uri: "http://yoursiteurl/_vti_bin/ListData.svc/LookupListName(2)"
            }
        }
    ]
});

此示例假定您的查阅列名为 MultiLookupColumnName，您的查阅列所查找的列表标题为 LookupListName，并且您要设置 multi-lookup 字段以查找 ID 为 1 和 2 的项目。

在您的代码中，您将使用 data 变量代替 itemProperties 变量。

为了完整起见，这里有一个没有 jQuery 的完整示例：

var idOfItemToUpdate = 1;
var url = "/serverRelativeUrl/_vti_bin/ListData.svc/YourListName("+idOfItemToUpdate+")"
var data = JSON.stringify({
    MultiLookupColumnName:[
        {__metadata:{uri:"http://yoursiteurl/_vti_bin/ListData.svc/LookupListName(1)"}},
        {__metadata:{uri:"http://yoursiteurl/_vti_bin/ListData.svc/LookupListName(2)"}}
    ]
});
var xhr = new XMLHttpRequest();
xhr.open("POST",url,true);
xhr.setRequestHeader("X-HTTP-Method", "MERGE");
xhr.setRequestHeader("If-Match", "*");
xhr.setRequestHeader("Content-Type","application/json");
xhr.send(data);

使用 REST 从多值查找字段中删除选择

请注意，要从 multi-selection 查找字段中删除值，您需要使用不同的操作。上面的操作只增加了选择的值。

要从字段中删除选定的值，请使用 DELETE 操作，如下所示：

var xhr = new XMLHttpRequest();
xhr.open("DELETE",
    "/serverRelativeUrl/_vti_bin/ListData.svc/YourListName(1)/$links/MultiLookupColumnName(2)",
    true);
xhr.send();

该代码将从名为 YourListName 的列表中 ID 为 1 的项目的名为 MultiLookupColumnName 的字段中删除项目 ID 为 2 的查找值。

（你能画出那句话吗？）

脚注：没有 jQuery

的回调函数

我在上面的示例中使用了 XMLHttpRequest，但我不希望这给您带来任何麻烦。

如果您决定使用 built-in XMLHttpRequest 而不是 jQuery/AJAX 包装器，您可以使用其 onreadystatechange 事件并向其传递回调函数，如下所示：

xhr.onreadystatechange = function(){
    if(xhr.readyState == 4){
        myCallbackFunction(xhr.status, xhr.responseText);
    }
};

function myCallbackFunction(status, text){
    // decide what to do based on the status
}
