Javascript RetreiveMultpleRecords:
Following is detail sample code to retrieve a record using Web API in Dynamics CRM.
/*
entityName: entityName is the plural entity logical name of entity e.g for account it is accounts. for opportunity it is opportunities
query: the odata query
return:-Entity records
*/
function retrieveMultiple(entityName , query) {
var data = null;
var req = new XMLHttpRequest();
req.open('GET', Xrm.Page.context.getClientUrl() + "/api/data/v8.2/" + entityPlurarName + query, 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.send();
if (req.readyState == 4) {
if (req.status == 200) {
data = JSON.parse(req.response);
}
else {
var error = JSON.parse(req.response).error;
console.log(error.message);
}
}
return data
}
You can call the above retrieveMultiple method as:var data = retrieveMultiple('roles', "?$select=roleid&$filter=name eq 'Project Manager'");
if (data != null && data.value.length > 0)
{
var PMRoleID= data.value[0].roleid;
}
