This is the jQuery code
success: function (html) {
         var text = $(html).text();
         if (text == '') {
            location.reload();
         } else {
            $("#warning2").html(html);
         }
 }
What I want is to convert $(html).text(); to plain JavaScript
Here is my plain JavaScript code but the page will not reload unlike jQuery code.
xhttp.onreadystatechange = function() 
{
    if (xhttp.readyState == 4 && xhttp.status == 200)
       {
       if (xhttp.responseText == "" || xhttp.responseText.textContent == "")
         location.reload();
       else
         document.getElementById("warning2").innerHTML = xhttp.responseText;
      }
};
