Posted on by ShubhamJain7

Please can someone help me to make a kind of intermediate function or way by which we can call the function having Xrm.webApi call synchronously in any synchronous function without the use of async or await keywords in the existing functions name(in intermediate function async and await will work) like below :

function show(){

//code

var result=function webapicall(); // result:undefined error as it doesn't wait for api call to finish and move to next statement as the xrm.webApi calls are asynchronous, please help me in writing such code without async or await keywords which will execute this synchronously.

alert();

//synchronous code

//more code

}

function webapicall()

{

xrm.webApi.retrievemultiplerecords().then(successcallback,error function)

return response;

}

That won't work as I mentioned in my first reply.

Put your sync code into success handler. Something like

show().then(function success(result){

//your sync code here

});

Thanks Andrew , it worked but if i want to store the response in the calling variable than is it possible like

var b=show().then(function success(result){});

synchronous code

and rest of the synchronous code...?

The main reason why your code doesn't work the right way is that the show method has to return the Promise instead of the data itself. I refactored the code of the show function:

function show() { var fetchXml= "" " " " " " " " " " " " " " " " " " " " " ""; fetchXml ="?fetchXml=" encodeURIComponent(fetchXml); var account="account"; return new Promise(function(resolve, reject) { parent.Xrm.WebApi.retrieveMultipleRecords(account, fetchXml).then( function (result) { var response=result.entities; resolve(response); }, function (error) { reject(error); }); }); }

Thanks Andrew, Could you please share a sample code to handle this with promises as when i am trying with .then() ..i am getting error :cannot read property than of null....

Below is my code for reference

function getRecord()
{

var b=show().then(function success(result){;
var fetchXml= "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>"+
" <entity name='account'>" +
" <attribute name='name' />" +
" <attribute name='telephone1' />" +
" <attribute name='address1_city' />" +
" <attribute name='primarycontactid' />" +
" <attribute name='statecode' />" +
" <filter type='and'>" +
" <condition attribute='name' operator='like' value='Adventure Works'/>" +
" </filter>" +
" </entity>"+
"</fetch>";
fetchXml ="?fetchXml=" + encodeURIComponent(fetchXml);
var account="account";
var records=parent.Xrm.WebApi.retrieveMultipleRecords(account, fetchXml);
parent.Xrm.WebApi.retrieveMultipleRecords(account, fetchXml).then( function success(response){

alert("getRecord");
alert("namaste"+response.entities[0].name);
},
function (error) {
alert(error.message);
}
);
});

}

function show()
{

var fetchXml= "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>"+
" <entity name='account'>" +
" <attribute name='name' />" +
" <attribute name='telephone1' />" +
" <attribute name='address1_city' />" +
" <attribute name='primarycontactid' />" +
" <attribute name='statecode' />" +
" <filter type='and'>" +
" <condition attribute='name' operator='like' value='Adventure Works'/>" +
" </filter>" +
" </entity>"+
"</fetch>";
fetchXml ="?fetchXml=" + encodeURIComponent(fetchXml);
var account="account";
var response=null;
parent.Xrm.WebApi.retrieveMultipleRecords(account, fetchXml).then(
function first(result) {
alert("show");
response=result.entities;

return response;
},
function (error) {

}
);

return response;
}

Hello,

I'm afraid you won't be able to do that in a direct way. You will have to use either async/await or promises.
