Hi,
I have added a button on home page grid which will be visible only when a single record is selected. On click of this button, I want to retrieve value from another entity's record using javascript code.
Any help would be appreciated !
Thanks,
Shreya
Hi Shreya,
We can add following modifications to make the function be a synchronous call.
1. set the last parameter to "false": req.open("GET", Xrm.Page.context.getClientUrl() "/api/data/v9.1/contacts" query, false);
2. remove the req.onreadystatechange function.

var query = "?$filter=contains(lastname,'mao')"
var list = [];
list = synchronousCall(query);
console.log(list[0]);
function synchronousCall(queryStr) {
var arr = [];
// Native XMLHttpRequest
var req = new XMLHttpRequest();
req.open("GET", Xrm.Page.context.getClientUrl() "/api/data/v9.1/contacts" queryStr, false);
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.send();
if (req.readyState === 4) {
//req.onreadystatechange = null;
if (req.status === 200) {
var result = JSON.parse(req.response);
for (var i = 0; i < result.value.length; i ) {
arr.push(result.value[i]);
}
} else {
Xrm.Utility.alertDialog((JSON.parse(req.response).error).message);
}
return arr;
};
}
Result:
In Chrome, it will notify us that we sent Synchronous XHR.

Hi,
Thanks for your help!!.
I was looking for a synchronous call but I have managed to get the desired result using Asynchronous Client Web Api.
Hi Shreya,
How do you want to retrieve records? For example by Web API?
We can use Client API(Xrm.Page or Xrm.Utility) in JavaScript web resource(command of button) directly, as what we do in form.
Sample code below will retrieve contacts whose lastname field contains 'mao'.
var query = "?$filter=contains(lastname,'mao')"
// Native XMLHttpRequest
var req = new XMLHttpRequest();
req.open("GET", Xrm.Page.context.getClientUrl() "/api/data/v9.1/contacts" query, 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 ) {
// console.log(result.value[i]);
}
} else {
Xrm.Utility.alertDialog(this.statusText);
}
}
};
req.send();
// Client API SDK
Xrm.WebApi.retrieveMultipleRecords("contact", query).then(
function success(result) {
if (result.entities.length > 0) {
for (var i = 0; i < result.entities.length; i ) {
console.log(result.entities[i]);
}
} else {
console.log("No data");
}
},
function (error) {
console.log(error.message);
}
);

Hi Clofly,
Thanks for your response.
I want to retrieve records from an entity on button click irrespective of the selected record.
Hi Shreya,
Do you want to pass id of selected record to your JavaScript function when clicking the button?
If so, you can pass "SelectedControlSelectedItemIds" parameter(Crm Parameter) to the function.
Result:
Please take articles below as reference to understand how to use other parameters.
