add the test inside the sendRequest as it is a call back else use setTimeOut which will wait for the value to be populated

Inserting an element in a specific id based on a data attribute

I am trying to dynamically insert elements within a loop, in to the corresponding DIVs based on the dataset values. Basically if the two elements have matching dataset value, it should be inserted in to a specific div.
The dataset values are unique, however in some cases the dataset values can appear more than once.
I have used the following code in another part of the project I'm working on, however I can't seem to make it work with the next thing I need to do.
var callingPointsWrapper = document.querySelectorAll(".callingstations");
var currentCallingWrapper = [...callingPointsWrapper].find((wrapper) => wrapper.dataset.callingpointsid === trainUID);
var callingWrapperFragment = document.createRange().createContextualFragment(callingPointsTemplate);
// add to correct element
callingPointsWrapper.appendChild(callingPointsTemplate);
All my code is shown below in context. Thanks in advance.

after calling this function in decument. ready section it is not retrieving any data but there is ine error which i can see in console of browser that is as below

You will click on the correct request in the left hand side panel, then select "Inspectors" in the right hand side top panel. Then choose between the different request and response options.

How can access the data recieved from API outside of this function

I have used node.js and request.js to access form information from our email services API. With the console.log in the function I am able to see all the info that I need. I have tried to access it outside of the function with dot notation(request.missionStatement) which I don't think is right. I want to be able to display this on a page within an express.js app.
var request = require('request');
// Basic Authentication credentials
var username = "user";
var password = "password";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
// Search for Custom Data Objects Affiliate Falculty form
request(
{
url : "url to api",
headers : { "Authorization" : authenticationHeader }
},
function (error, response, body) {
var parsedData = JSON.parse(body);//convert text from API to JSON file
var missionStatement = [];
for (var i = 0; i < parsedData.elements.length ; i++) {
var individualStatement = "";
//Get text submission from form and push into array
individualStatement += (parsedData.elements[i].fieldValues[4].value + ", " + parsedData.elements[i].fieldValues[2].value + " " + parsedData.elements[i].fieldValues[3].value + ", " + parsedData.elements[i].fieldValues[0].value);
missionStatement.push(individualStatement);
};
console.log(missionStatement)
}
);

The variable missionStatement is a local variable declared inside an anonymous function passed as an argument to the request function, and thus it is inaccessible once the anonymous function returns. You must save your result elsewhere. Try something like this:
var request = require('request');
// Basic Authentication credentials
var username = "user";
var password = "password";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
var result;
// Search for Custom Data Objects Affiliate Falculty form
request(
{
url : "url to api",
headers : { "Authorization" : authenticationHeader }
},
function (error, response, body) {
var parsedData = JSON.parse(body);//convert text from API to JSON file
var missionStatement = [];
for (var i = 0; i < parsedData.elements.length ; i++) {
var individualStatement = "";
//Get text submission from form and push into array
individualStatement += (parsedData.elements[i].fieldValues[4].value + ", " + parsedData.elements[i].fieldValues[2].value + " " + parsedData.elements[i].fieldValues[3].value + ", " + parsedData.elements[i].fieldValues[0].value);
missionStatement.push(individualStatement);
};
result = missionStatement;
displayResult();
});
function displayResult() {
console.log(result);
}
Your missionStatement will now be saved in result, but only after the anonymous callback to request() has been called (when the actual request is finished).

XMLHttpRequest calls not finishing before return statement so undefined

I'm attempting to count how many items total are in the database I'm querying. It's third party so it's cross domain XMLHttpRequests but I'm making the method in a Chrome Extension and the permissions bit in the manifest.json let's it work nicely.
The problem I seem to be having is this: I'm looping through a list of categories and counting the amount in each before the XMLHttpRequests are coming back from the external server. The methods are started by the press of a button of id="countButton". Here's the relevant javascript/jQuery:
//simple listener for the button
document.getElementById('countButton').addEventListener('click', function() runTotalCount()}, true);
//loops through a list of categories in a drop down with values 0-36
function runTotalCount(){
var sum = 0;
$('#categorySelect option').each(function(){
var value = $(this).val();
sum += retrieveCategoryCount(value);
alert("New Sum = " + sum);
});
var total = "<p>Total items in Sum is " + sum + "</p>";
document.getElementById('results').innerHTML = total;
}
//actually makes the request and sums the items count for each category
//the server response is a json with an alphabetized "items" per category
function retrieveCategoryCount(num){
var sum = 0;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
if (xhr.readyState == 4 && xhr.status == 200){
var str = xhr.responseText;
alert("str = " + str);
var json = $.parseJSON(str);
alert("JSON = " + json);
for(item in json.alpha){
alert("items count = " + json.alpha[item].items);
sum += json.alpha[item].items;
}
alert("Category Sum = " + sum);
return sum;
}
}
xhr.open(
"GET",
"http://services.runescape.com/m=itemdb_rs/api/catalogue/category.json?category=" + num,
true);
xhr.send(null);
}
As it is the stuff within the onreadystate for retrieveCategoryCount never gets called because the XMLHttpRequests are still pending by the time the function finishes. On synchronous calls the alert("Category Sum = " + sum); returns the right number but then the function return just below it is NaN (I'd rather not hang up the browser though so asynchronous is what I'd prefer for a solution).
What needs to change to properly get the item count? Thanks in advance.
UPDATE:
I've also tried code for retrieveCategoryCount of this:
function retrieveCategoryCount(num){
var sum = 0;
$.getJSON("http://services.runescape.com/m=itemdb_rs/api/catalogue/category.json?category=" + num, function(data){
for(item in data.alpha){
alert("items count = " + data.alpha[item].items);
sum += data.alpha[item].items;
}
alert("Category Sum = " + sum);
return sum;
});
}
The problem here is that the callback never gets run because the request is still pending by the time the value returned from the function is added to "sum".

You can put the code that should happen AFTER the async call completes into a callback function and pass that into your async function, then have it callback.
var sum = 0,
setTotalCount = function(data){
.. stuff to set the dom element based on callback
};
$('#categorySelect option').each(function(){
var value = $(this).val();
retrieveCategoryCount(value, setTotalCount);
});
function retrieveCategoryCount(num, callback){
var sum = 0;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
if (xhr.readyState == 4 && xhr.status == 200){
var str = xhr.responseText;
alert("str = " + str);
var json = $.parseJSON(str);
alert("JSON = " + json);
for(item in json.alpha){
alert("items count = " + json.alpha[item].items);
sum += json.alpha[item].items;
}
alert("Category Sum = " + sum);
callback(sum); // callback the function you passed in
}
}
xhr.open(
"GET",
"http://services.runescape.com/m=itemdb_rs/api/catalogue/category.json?category=" + num,
true);
xhr.send(null);
}

The callback function you pass to onreadystatechange is not retrieveCategoryCount. It's return value is lost because the function is only called in response to the readystatechange event.
Do what you need to do with the data in the callback. Don't try to return the data.
