To retrieve meta data of global optionSet in Web API, first you will need to retrieve meta data id of option Set.
So i create two functions ,
RetrieveGlobalOptionSetMetaDataId("OptionSetSchemaName") function
will retrieve meta data id of optionSet by passing schema name of option , then pass meta data id to
RetrieveGlobalOptionSetOptionsMetaData(optionSetMetaDataId)
it will retrieve meta data of optionSet.
I am binding options of global optionSet to Select element in Html Page ,
var globalOptionSetMetaDataId = RetrieveGlobalOptionSetMetaDataId("OptionSetSchemaName");
RetrieveGlobalOptionSetOptionsMetaData(globalOptionSetMetaDataId );
function RetrieveGlobalOptionSetMetaDataId(OptionSetSchemaName) {
var globalOptionSetMetaDataId = null;
var context = parent.Xrm.Page.context;
var webapiQuery = context.getClientUrl() + "/api/data/v8.0/GlobalOptionSetDefinitions?$select=Name";
var service = new XMLHttpRequest();
service.open("GET", webapiQuery, false);
service.setRequestHeader("Accept", "application/json");
service.setRequestHeader("Content-Type", "application/json; charset=utf-8");
service.setRequestHeader("OData-MaxVersion", "4.0");
service.setRequestHeader("OData-Version", "4.0");
service.send();
if (service.readyState == 4 /* complete */) {
if (service.status == 201 || service.status == 200) {
var RetrieveService = eval('(' + service.responseText + ')');
if (RetrieveService.value.length > 0) {
for (var i = 0; i < RetrieveService.value.length; i++) {
if (RetrieveService.value[i].Name == OptionSetSchemaName) {
globalOptionSetMetaDataId = RetrieveService.value[i].MetadataId;
break;
}
}
}
}
}
return globalOptionSetMetaDataId ;
}
function RetrieveGlobalOptionSetOptionsMetaData(optionSetMetaDataId) {
var context = parent.Xrm.Page.context;
var webapiQuery = context.getClientUrl() + "/api/data/v8.0/GlobalOptionSetDefinitions(" + optionSetMetaDataId + ")";
var service = new XMLHttpRequest();
service.open("GET", webapiQuery, false);
service.setRequestHeader("Accept", "application/json");
service.setRequestHeader("Content-Type", "application/json; charset=utf-8");
service.setRequestHeader("OData-MaxVersion", "4.0");
service.setRequestHeader("OData-Version", "4.0");
service.send();
if (service.readyState == 4 /* complete */) {
if (service.status == 201 || service.status == 200) {
var RetrieveService = eval('(' + service.responseText + ')');
if (RetrieveService.Options.length > 0) {
var options = "";
for (var i = 0; i < RetrieveService.Options.length; i++) {
var optionLabel = RetrieveService.Options[i].Label.UserLocalizedLabel.Label;
var optionValue = RetrieveService.Options[i].Value;
options += "<option value='" + optionValue + "'>" + optionLabel + "</option>";
}
$("#dropdownReason").html(options);
}
}
}
}
