我有一个包含2个自定义字段的表单：“选项集”和“多行文本”。我将JavaScript文件作为WebResource上传，并将该函数添加到Form的Onload事件中。 我想知道如何使用JavaScript将所有选项集项复制到多行文本框。
答案 0 :(得分：0)
尝试使用此代码段：此请求获取选项集的元数据，并以XML格式返回CRM中的所有数据。
if (typeof (SDK) == "undefined") { SDK = { __namespace: true }; }
//This will establish a more unique namespace for functions in this library. This will reduce the
// potential for functions to be overwritten due to a duplicate name when the library is loaded.
SDK.OptionSet = {
_getServerUrl: function () {
///<summary>
/// Returns the URL for the SOAP endpoint using the context information available in the form
/// or HTML Web resource.
///</summary>
var ServicePath = "/XRMServices/2011/Organization.svc/web";
var serverUrl = "";
if (typeof GetGlobalContext == "function") {
var context = GetGlobalContext();
serverUrl = context.getServerUrl();
}
else {
if (typeof Xrm.Page.context == "object") {
serverUrl = Xrm.Page.context.getServerUrl();
}
else
{ throw new Error("Unable to access the server URL"); }
}
if (serverUrl.match(/\/$/)) {
serverUrl = serverUrl.substring(0, serverUrl.length - 1);
}
return serverUrl + ServicePath;
},
GetOptionSetValuesRequest: function () {
var requestMain = ""
requestMain += "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";

var req = new XMLHttpRequest();
req.open("POST", SDK.OptionSet._getServerUrl(), false)
req.setRequestHeader("Accept", "application/xml, text/xml, */*");
req.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
req.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute");

//work with the response here
var strResponse = req.responseXML.xml;

响应将在strResponse中。你需要解析它。这是一个非常大的反应，所以我只提供其中的一部分：

接下来，您需要解析此XML并使用CRM表单JavaScript将标签放置在您想要的位置。您可以在// c中找到选项名称：OptionSet / c：Options / c：OptionMetadata / c：Label / a：LocalizedLabels / a：Label tags。
