Question

attempting to call a method for creating a display container for the

xmlhttp.responseText;//createDisplayElement()

In the following:
JS BIN Document

No Errors to the Error console in FF, but the behavior is off, not refreshing the page properly.

Answer 1

I see 2 issues in the code.

1. obj is not defined properly.
2. plain text (xmlhttp.responseText) is appended to a p element.

Both of them are corrected below.

Try this,

function makerequest(serverPage, objID)
{

    xmlhttp.open("GET", serverPage);
    xmlhttp.onreadystatechange = function(){

        if(xmlhttp.status == 200 || xmlhttp.readyState == 4){

            createDisplayElement(objID);
        }
    };

    xmlhttp.send(null);
}

function createDisplayElement(objID){
    var obj = document.getElementById(objID);
    var para = document.createElement("p");
    obj.appendChild(para);
    var txtNode = document.createTextNode(xmlhttp.responseText);
    para.appendChild(txtNode);

}
