[Solved] How do I convert jQuery AJAX code to vanilla JavaScript? [duplicate]

by


Using XMLHttpRequest

var r = new XMLHttpRequest();
r.open('GET', 'csv_data.csv');
r.onreadystatechange = function () {
    if (r.readyState != 4 || r.status != 200) return;
    successFunction(r.responseText);
};
r.send();

Haven’t tested it.
