获取查找值的属性 - javascript / CRM 2011

Question

我想用所选主题的描述填充 CRM 案例的描述（在选择主题之前，案例描述将被禁用）。 我将使用它来根据主题自动填充一些问题。 如何检索主题描述？我可以获得 ID 和主题名称，但似乎无法在网络上找到比这 2 个属性更多的东西。

非常感谢！

如果您要退回一件商品，那么我建议您使用“Retrieve”而不是“RetrieveMultiple”。正如您在上面所做的那样，您可以通过在列列表中包含“描述”来获取描述字段。

var xml = "" + 
      "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + 
      "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" + 
      GenerateAuthenticationHeader() +
      "<soap:Body>" +
        "<Retrieve xmlns='http://schemas.microsoft.com/crm/2007/WebServices'>" +
        "<entityName>subject</entityName>" +
        "<id>" + Xrm.Page.getAttribute("subjectid").getValue()[0].id + "</id>" +
        "<columnSet xmlns:q1='http://schemas.microsoft.com/crm/2006/Query' xsi:type='q1:ColumnSet'>" +
            "<q1:Attributes>" +
                "<q1:Attribute>description</q1:Attribute>" +
            "</q1:Attributes>" +
        "</columnSet>" +
        "</Retrieve>" +
        "</soap:Body>" +
        "</soap:Envelope>";

var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");

xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xmlHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/Retrieve");
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.setRequestHeader("Content-Length", xml.length);
xmlHttpRequest.send(xml);

var resultXml = xmlHttpRequest.responseXML;

if (resultXml.selectSingleNode("//q1:description") != null)
{
    Xrm.Page.getAttribute("description").setValue(resultXml.selectSingleNode("//q1:description").nodeTypedValue);
}
