Fetching data from two API to merge them in one table

First of all,
you can see below, my working program to fetch Data from two different APIs in two different tables.
First table contains the data from an API : {Cycle, Delegated Stack, Share, expected payment}
The second one gets the data from another API to get : {the cycle, paid reward}
https://codepen.io/alexand92162579/pen/arJqmv?editors=1010
The second Code pen is the same thing but I want to merge the two tables according to the value of the cycle:
https://codepen.io/alexand92162579/pen/OGdjLJ?editors=1011
According to what I read online, I need to use Promises. I have tried this multiple times but never succeeded to make it work !
To try it, enter the Key KT19www5fiQNAiqTWrugTVLm9FB3th5DzH54 in the inputbox.
I will make a donation of 30xtz if someone helps me on this one.
// Fonction to fetch the data for every cycle on the first API
// Data Recolted (Cycle, Balance, Share, Expected Reward, Fee, Status)

I'm not sure why this isn't XML information isn't printing to the screen

I have written this code which is supposed to print the information from the xml file into a list for each faculty member. I want to eventually place all of these into a table, but need to know how to print them to the screen first.
function init() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function () {
if (this.readyState == 4 && this.status == 200) {
console.log(this.responseXML);
var faculty = this.responseXML.getElementsByTagName("faculty");
var strOut = "<ul>";
for (i = 0; i < faculty.length; i++) {
var name = faculty[i].getElementsByTagName("name")[0].innerHTML;
var title = faculty[i].getElementsByTagName("title")[0].innerHTML;
var office = faculty[i].getElementsByTagName("office")[0].innerHTML;
var phone = faculty[i].getElementsByTagName("phone")[0].innerHTML;
var email = faculty[i].getElementsByTagName("email")[0].innerHTML;
strOut += "<li><a href = " + name + title + "</a></li>";
}
strOut += "<ul>";
document.getElementById("output").innerHTML = strOut;
}
};
xhttp.open("GET", "faculty.xml", true);
xhttp.send();
}
window.onload = init;
Here is the XML file:
<facultyInfo>
<faculty>
<name>Prof A</name>
<title>Professor and Program Coordinator</title>
<office>CI 555</office>
<phone>(999-999-9999</phone>
<email>ProfA#school.edu</email>
</faculty>
<faculty>
<name>Prof B</name>
<title>Visiting Professor</title>
<office>CI 333</office>
<phone>999-999-9999</phone>
<email>ProfB#school.edu</email>
</faculty>
</facultyInfo>

This line:
strOut += "<li><a href = " + name + title + "</a></li>";
... is both malformed and probably not what you intended. Between the missing quotes for the href attribute, missing the ">" to close off the <a> start, and not putting any text in between <a></a>, this results in a link tag where the link destination (href) is set, but the actual text to show to the user is not set. I don't see any links in your XML (maybe that is for the future), so for now you probably want something like this:
strOut += '<li>' + name + ', ' + title + '</li>';
Here is a quick demo with your XML input:
<div id="output"></div>
<script>
var xmlString = '<facultyInfo> <faculty> <name>Prof A</name> <title>Professor and Program Coordinator</title> <office>CI 555</office> <phone>(999-999-9999</phone> <email>ProfA#school.edu</email> </faculty> <faculty> <name>Prof B</name> <title>Visiting Professor</title> <office>CI 333</office> <phone>999-999-9999</phone> <email>ProfB#school.edu</email> </faculty> </facultyInfo>';
var xmlDoc = (new DOMParser()).parseFromString(xmlString,'text/xml');
// var faculty = this.responseXML.getElementsByTagName("faculty");
var faculty = xmlDoc.getElementsByTagName("faculty");
var strOut = "<ul>";
for (i = 0; i < faculty.length; i++){
var name = faculty[i].getElementsByTagName("name")[0].innerHTML;
var title = faculty[i].getElementsByTagName("title")[0].innerHTML;
var office = faculty[i].getElementsByTagName("office")[0].innerHTML;
var phone = faculty[i].getElementsByTagName("phone")[0].innerHTML;
var email = faculty[i].getElementsByTagName("email")[0].innerHTML;
strOut += '<li>' + name + ', ' + title + '</li>';
}
strOut += "<ul>";
document.getElementById("output").innerHTML = strOut;
</script>

Multiple JSON files in one request from Javascript

I have two different codes for two different URL to fetch data. Code is as below :
Code 1 :

Both the codes are in two different html files and as an individual, both runs fine and fetches data.
I want to fetch the data of both the url in one html, i.e. I want to merge both the files and retreive data of both the request in single HTML file.
Can u suggest how can i do it? I have searched on stackoverflow but not able to find the right solution.
Thanks in advance.

AJAX works when in debug mode but not in real time

My code works when i'm slowly stepping through in debug mode, but when i try it in real time, it doesn't seem to want to update the page.
Here is the javascript:
searchButton = document.getElementById("searchButton");
var searchBox = document.getElementById('searchBox');
searchButton.addEventListener("click", searchItem);
function searchItem(){
searchString = searchBox.value;
article = document.getElementById("homeSection");
var xmlhttp = getXmlHttpRequestObject();
var string = '';
if(xmlhttp){
xmlhttp.onreadystatechange = function(){
if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
var response = JSON.parse(xmlhttp.responseText);
for(var i=0; i<response.length; i++){
string += '<section class="searchResult">';
string += '<h1>' + response[i].Name + '</h1>';
string += '<p class="photo"></p>';
string += '<p class="price">£' + response[i].Price + '</p>';
string += '<p class="productID">ID: ' + response[i].ID + '</p>';
string += '<p class="description">' + response[i].Description + '</p>';
string += '<p class="quantity">Quantity: ' + response[i].Quantity + '</p>';
string += '</section>';
}
article.innerHTML = '<h1>Search</h1><section><h1 class="bottomBorder">You searched for: "' + searchString + '"</h1></section>';
article.innerHTML += string;
}
};
xmlhttp.open("GET", "search.php?search=" + searchString, true);
xmlhttp.send(null);
}
}

Two things you need to do
Cancel the click action that is triggering the function
Second encode the content you are sending to the server
Updated code:
function searchItem (event){
event.preventDefault();
var searchStringEnc = encodeURIComponent(searchBox.value);
...
xmlhttp.open("GET", "search.php?search=" + searchStringEnc, true);

It's not working on IE, rest of the responses and suggestions here are correct. Why IE only? because you have undefined vars:
searchString = searchBox.value;
correct
var searchString = searchBox.value;
To check if your script is truly working just alert the formatted string.
article.innerHTML += string;
alert(string);
then you will know what is wrong.

If you're using a button in a form to post with AJAX, make sure the button type="button" or it will act as a submit button and submit the form. This little feature cost me days of frustration!!!

Converting firefox javascript to IE javascript

I've been trying to get some AJAX code that runs fine in FireFox to run in IE.
I'm running into some trouble with updating some tables in the script though. I've seen numerous other people have similar issues, but none of the solutions they've found have worked for me. The problem occurs first on the line
qe3Table.innerHTML =
"<tr>\n" +
" <th>Name</th>\n" +
" <th>Status</th>\n" +
" <th>View Status</th>\n" +
"</tr>\n";
Where I'm getting the error "'null' is null or not an object"
I'm pretty sure that all of my other errors are of the same type as this one, my AJAX script and some accompanying javascript is below.
<script type="text/javascript">
<!--
//obtains the box address for a QE3 on the system for the given index
function getQE3BoxAddressHash(index)
{
var retVal = 0x00000100; //initial value for QE3 boxes
retVal |= (index & 0x000000FF);
return retVal;
}
//obtains the box address for a QED on the system for the given index
function getQEDBoxAddressHash(index)
{
var retVal = 0x00001300; //initial value for QED boxes
retVal |= ((index & 0x0000000F) << 4);
retVal |= ((index & 0x000000F0) >> 4);
return retVal;
}
-->

</script>

The problem is probably with:
var qe3Table = document.getElementById("QE3_TABLE");
If you're running this script before the body is loaded, that won't exist. Check to see if that variable has anything in it.

I Tried both of your guys' fixes but they didn't seem to help. In the end, I converted all calls of the form:
qe3TableNew.innerHTML = ("<tr>\n" +" <th>Name</th>\n" +" <th>Status</th>\n" +" <th>View Status</th>\n" +"</tr>\n");
to
var row;
var cell;
var text;
var font;
row = document.createElement("tr");
qe3TableNew.appendChild(row);
cell = document.createElement("th");
row.appendChild(cell);
text = document.createTextNode("Name");
cell.appendChild(text);
cell = document.createElement("th");
row.appendChild(cell);
text = document.createTextNode("Status");
cell.appendChild(text);
cell = document.createElement("th");
row.appendChild(cell);
text = document.createTextNode("View Status");
cell.appendChild(text);
This seemed to solve it, so I believe it has to do with IE's inability to handle changes to innerHTML.
Thanks for the help guys.

At least one issue (which could produce the above symptoms) is the line:
window.onload=init();
Hint: the () operator executes the function immediately and evaluates to the return value. This in turn may allow the XHR handler (in certain situations) to fire at a time when the DOM may not be ready.
Happy coding.
