Question

我正在使用D-CRM 2016，我试图在客户端（js）中获得选项集的标签，但出现错误，找不到原因：那就是我的代码：

SDK.Metadata.RetrieveAttribute("myEntity", "myFieldName", null, false,
                function (result) {
                alert(result);
                for (var i = 0; i < result.OptionSet.Options.length; i++) {
                var loopText = result.OptionSet.Options[i].Label.LocalizedLabels[0].Label;
                var loopValue = result.OptionSet.Options[i].Value;

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

我的错误：

Uncaught TypeError: _Context(...).getServerUrl is not a function

无论何时您尝试进行客户端休息呼叫，我总是建议使用Jason Lattimer的CRM Rest Builder（https://github.com/jlattimer/CRMRESTBuilder）。您可以使用“格式化的值”选项访问文本标签。

主要问题是使用的SDK。我真的不能为您调试它。

但是，这里有一个工作示例正在返回标签和值。您可以添加标头（首选），以告诉api也返回标签：

var odataEndPoint = Xrm.Page.context.getClientUrl() + '/api/data/v8.2/';

function GetDomainName(entityId) {
        var result = null;

        var req = new XMLHttpRequest();
        req.open("GET", odataEndPoint + 'systemusers(' + TrimGuid(entityId) + ')/', false);
        req.setRequestHeader("Accept", "application/json");
        req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
        req.setRequestHeader("OData-MaxVersion", "4.0");
        req.setRequestHeader("OData-Version", "4.0");
        req.setRequestHeader("Prefer", "odata.include-annotations=\"OData.Community.Display.V1.FormattedValue\"");
        req.onreadystatechange = function () {
            if (this.readyState == 4) {
                req.onreadystatechange = null;
                if (this.status == 200) {
                    if (this.response) {
                        result = JSON.parse(this.response);
                    }
                }
                else {
                    var parsed = JSON.parse(this.response);
                    console.error(parsed.error.message)
                }
            }
        };

        req.send();
        return result;
    };
