i am trying below

where the html table data coming from

i am not clear on what below code doing either

<!DOCTYPE html>

<h2>Make a table based on JSON data.</h2>

<p id="demo"></p>

var obj, dbParam, xmlhttp, myObj, x, txt = "";
obj = { "table":"customers", "limit":20 };
dbParam = JSON.stringify(obj);
xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        myObj = JSON.parse(this.responseText);
        txt += "<table border='1'>"
        for (x in myObj) {
            txt += "<tr><td>" + myObj[x].name + "</td></tr>";
        txt += "</table>"        
        document.getElementById("demo").innerHTML = txt;
};"POST", "json_demo_db_post.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("x=" + dbParam);



what is dbparam why we need to stringify json and send that

dbParam = JSON.stringify(obj);

please advise
