    What you can do in javascript is the following

    //create an empty array
var payload = [];

//push objects into that array
payload.push('--batch_340293023');
payload.push('Content-Type......');
payload.push('');

//create the payload that you can use in the post message
var postdata = payload.join('\r\n');


    This worked for me.

    Hi Alagunellaikumar,

    Please try the following code. This is an example to create multiple task for new account.

    //Create 1 Js web resource method that will handle batch request
function executeBatch (payload, batchId, successCallback, errorCallback, callerId) {
 
var req = new XMLHttpRequest();
req.open(“POST”, “Your Web Api Here” + “$batch”), true);
req.setRequestHeader(“Accept”, “application/json”);
req.setRequestHeader(“Content-Type”, “multipart/mixed;boundary=batch_” + batchId);
req.setRequestHeader(“OData-MaxVersion”, “4.0”);
req.setRequestHeader(“OData-Version”, “4.0”);
 
req.onreadystatechange = function () {
if (this.readyState == 4 /* complete */) {
req.onreadystatechange = null;
if (this.status == 200) {
if (successCallback) {
successCallback(this.response);
}
}
else {
if (errorCallback)
errorCallback(Sdk.WebApiOperation.errorHandler(this));
}
}
};
 
req.send(payload);
}
//Create CreateBatchTaskforAccount method to create task for new account
function CreateBatchTaskforAccount(accountUri )
{
//Generating random id for the payload object
 
var batchId = GetRandomId();
//Define tasks to be created:
var firstTask = {
subject: “new task for new account” + accountUri,
“regardingobjectid_account_task@odata.bind”: accountUri
};
//Note: Imortant here
var secondTask = {
subject: “second task”,
“regardingobjectid_account_task@odata.bind”: accountUri
};
//Start of ChangeSet
payload = [“–batch_” + batchId]
payload.push(“Content-Type: multipart/mixed;boundary=changeset_” + changeSetId);
payload.push(“”);
//First item in ChangeSet
payload.push(“–changeset_” + changeSetId);
payload.push(“Content-Type: application/http”);
payload.push(“Content-Transfer-Encoding:binary”);
payload.push(“Content-ID: 1”);
payload.push(“”);
payload.push(“POST ” + CrmSdk.RBEIApi.getWebApiUrl() + “tasks HTTP/1.1”);
payload.push(“Content-Type: application/json;type=entry”);
payload.push(“”);
payload.push(JSON.stringify(firstTask));
//Second item in ChangeSet
payload.push(“–changeset_” + changeSetId);
payload.push(“Content-Type: application/http”);
payload.push(“Content-Transfer-Encoding:binary”);
payload.push(“Content-ID: 2”);
payload.push(“”);
payload.push(“POST ” +  CrmSdk.RBEIApi.getWebApiUrl() + “tasks TTP/1.1”);
payload.push(“Content-Type: application/json;type=entry”);
payload.push(“”);
payload.push(JSON.stringify(secondTask));
//End of ChangeSet
payload.push(“–changeset_” + changeSetId + “–“);
payload.push(“”);
//Adding a GET request outside of the ChangeSet
payload.push(“–batch_” + batchId);
payload.push(“Content-Type: application/http”);
payload.push(“Content-Transfer-Encoding:binary”);
payload.push(“”);
//Retrieve all the tasks related to the account
payload.push(“GET ” + accountUri + “/Account_Tasks?$select=subject HTTP/1.1”);
payload.push(“Accept: application/json”);
payload.push(“”);
payload.push(“–batch_” + batchId + “–“);
executeBatch(payload.join(“\r\n”), batchId, function (response) {
alert(response);
 
}, function (error) {
alert(error);
});
}
//Generating random id for Payload object
Function GetRandomId (idLength) {
if (this.isNullOrUndefined(idLength))
idLength = 10;
if (this.isNumber(idLength)) {
if (idLength > 30) {
throw new Error(“Length must be less than 30.”);
}
}
else {
throw new Error(“Length must be a number.”);
}
var returnValue = “”;
var characters = “ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789”;
for (var i = 0; i < idLength; i++)
returnValue += characters.charAt(Math.floor(Math.random() * characters.length));
return returnValue;
}

    Should be simple, one block for a POST message to create a record and one for a PATCH message to update the record. My blog shows an example of POST (create) and DELETE.
