NodeJS XMLHttpRequest response

Question

I'm making and app and I need do get the number of verses of a chapter of the bible.

I'm getting the info from http://www.kingjamesbibleonline.org/

In order to do that I am making an XMLHttpRequest to send to the server from the function

getVerses()

from the site.

The problem that I am facing is that I'm not getting a .responseText from the XMLHttpRequest. When I use firebug and call that function, in the Network tab > Response tab I get nothing but on Network tab > Preview I get the answer.

Where is this answer coming from and what is the variable that has this value?

My node code is as follows:

let XMLHttpRequest2 = require("xmlhttprequest").XMLHttpRequest;



function getVerses() {

    let xmlhttp = new XMLHttpRequest2(); //: new ActiveXObject("Microsoft.XMLHTTP");

    xmlhttp.onreadystatechange = function() {

        if (xmlhttp.readyState == xmlhttp.DONE ) {

            if(xmlhttp.status == 200){

                console.log(xmlhttp.responseText);

            }

            else if(xmlhttp.status == 400) { }

            else { }

            }

    }

    xmlhttp.open("POST", "http://www.kingjamesbibleonline.org/ajax.php", true);

    xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");

    xmlhttp.send('callFunc=getMaxVerseForChapter&book='+'"Genesis"'+'&chapter='+'"2"');

}



getVerses();

Apparently the server is very strict and it expects the header to be called Content-Type and not Content-type. Some kind of poorly written stuff obviously (in PHP). Also get rid of the double quotes around the values you are sending.

Here you go:

let XMLHttpRequest2 = require("xmlhttprequest").XMLHttpRequest;

function getVerses() {
    let xmlhttp = new XMLHttpRequest2(); //: new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == xmlhttp.DONE ) {
            if(xmlhttp.status == 200){
                console.log(xmlhttp.responseText);
            }
            else if(xmlhttp.status == 400) { }
            else { }
        }
    }
    xmlhttp.open("POST", "http://www.kingjamesbibleonline.org/ajax.php", true);
    xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
    xmlhttp.send('callFunc=getMaxVerseForChapter&book=' + 'Genesis' + '&chapter=' + '2');
}

getVerses();

and since you are hardcoding the values, you don't really need string concatenation:

xmlhttp.send('callFunc=getMaxVerseForChapter&book=Genesis&chapter=2);
