Set up multiple time series request in Web SDK
Hi all,
I am working on a page which requires to send multiple time series requests at one time. However, as the requests are at promise (asynchronous) base. I cannot find a way to distinguish which result corresponds to its request when it is loaded and only result is returned (Without RIC). I wonder if there is a way to do that.
Thanks a lot for your help! I know it should have a trivial solution but i really have no idea how to fix this.
It would be helpful if you can build on the time series example.
//Create snapshot request via request() function.
function snapshot() {
var table = document.getElementById("myTable");
table.innerHTML='';
if (typeof sub !== 'undefined') {
sub.unsubscribe();
delete sub;
}
var intervalType = $("#select_intervalType").val();
var tsPromise = JET.Data.TimeSeries.request({"ric" : $("#RIC").val(),"view" : $("#VIEW").val(),"numberOfPoints": Number($("#numberOfPoints").val()),"timeZone" : "instrument","intervalType" : $("#select_intervalType").val(),"intervalLength" : 1});
tsPromise.then(resolve, reject);
}
function resolve(data){
var status = document.getElementById("status");
status.value = "Success";
data.....
}
//If request is rejected, then update status text area.
function reject(msg) {
var status = document.getElementById("status");
status.value = "Rejected: " + JSON.stringify(msg);
}

You can implement like this:
function snapshot() {
var intervalType = $("#select_intervalType").val();
var ricName = $("#RIC").val();
var tsPromise = JET.Data.TimeSeries.request({ "ric": $("#RIC").val(), "view": $("#VIEW").val(), "numberOfPoints": Number($("#numberOfPoints").val()), "timeZone": "instrument", "intervalType": $("#select_intervalType").val(), "intervalLength": 1 });
tsPromise.then(function (data) {
resolve(data, ricName);
}, function (msg) {
reject(msg, ricName);
});
}
function resolve(data, ricName){
var status = document.getElementById("status");
status.value = "Success";
console.log("### " + ricName + " ###");
if (data.length > 30000) {// too big data
console.log("Total Points:" + args.Data.length);
}
else {
if (data.length > 1) {
console.log(JSON.stringify(data, null, 4));
}
else {
console.log(JSON.stringify(data, null, 4));
}
}
}
//If request is rejected, then update status text area.
function reject(msg, ricName) {
var status = document.getElementById("status");
status.value = "Rejected: " + JSON.stringify(msg);
console.log("Rejected: "+ ricName);
