Hi NB,
As per my understanding, retrieving lookup fields data could be regarded as retrieving records of a specific entity,
so we could run code below to achieve your requirement:(initialize a variable, then append retrieved name value to that variable in for loop)
// var entity_type = formContext.getAttribute("lookupfield_name").getValue()[0].entityType;
var list = "";
var req = new XMLHttpRequest();
req.open("GET", formContext.context.getClientUrl() "/api/data/v9.1/accounts?$select=name", true);
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
req.onreadystatechange = function () {
if (this.readyState === 4) {
req.onreadystatechange = null;
if (this.status === 200) {
var result = JSON.parse(this.response);
for (var i = 0; i < result.value.length; i ) {
if (i < result.value.length - 1) {
list = result.value[i]["name"] ", ";
} else {
list = result.value[i]["name"];
}
}
formContext.getAttribute("new_introduction").setValue(list);
console.log(list);
} else {
var result = JSON.parse(this.response);
var alertStrings = { confirmButtonLabel: "Ok", text: result.error.message, title: "Error" };
var alertOptions = { width: 200, height: 150 };
Xrm.Navigation.openAlertDialog(alertStrings, alertOptions).then(
function success(result) {
console.log("Alert dialog closed");
},
function (error) {
console.log(error.message);
}
);
}
}
};
req.send();
e.g: Populate a custom single line of text field with all retrieved account records.
