Display tweets retrieved from database after onclick function

I am using JavaScript, PHP and HTML for my application. I have a SQL database that contains tweets. I need to query from database and display tweets after the keyword (connecting to a hyper tree) is clicked. I have researched and tried to include an external php file (generatetweets.php) inside myFunction() at index.php. However it's not working. Anyone can enlighten me or any reference for me to guide? Thank you in advance.

Extracted example2.js, where child.name refers to the keyword from hyper tree

JavaScript

onComplete: function() {
            //Log.write("done");

            //Make the relations list shown in the right column.
			//ONCLICK FUNCTION FOR KEYWORDS TO LOAD RELATED TWEETS
            var node = ht.graph.getClosestNodeToOrigin("current");
            var html = "<div><b>Keyword: " + node.name + "</b></div>";
            html += "<ul>";
            node.eachAdjacency(function(adj){
                var child = adj.nodeTo;
				var childName=child.name;
				html += '<a önclick="myFunction('+'''+child.name+'''+')">'+child.name + '</a>;
				
            });
            html += "br />";
            $jit.id('inner-details').innerHTML = html;
}

generatetweets.php

PHP

<?php
// connect to the database
include "mysqli.connect.php";

// create your SQL statment to retrieve everything from
// the users table
$sql = "SELECT * FROM post WHERE content LIKE '%school%' ORDER BY date DESC";

// run the query
$result = $mysqli->query($sql);

// check for error
if ($mysqli->errno)
{
  error_log($mysqli->error);
  echo "<br />Something's wrong";
  exit();
}

There's a missclick on line 13 of your first code-box:
onclick="myFunction(...)..." instead of "önclick=..."

As far as I know, this method will be easy and efficient to implement.
Inside the myFunction(), send a XMLHTTPREQUEST to that php page. And in that php page, where you are retrieving from DB, echo the HTML code that you want to display(this will contain the tweets and infos). Get this response in the Javascript function and add it to an empty HTML element in that page where you want to display.
