Xmlhttprequest Readystate Always Undefined

I'm following the PHP/AJAX tutorials at w3schools, and I've hit a bit of a roadblock at square one. Every time I call this function, the readystate is always undefined. function sh

Solution 1:

JS is case sensitive. You need to check the readyState property, not the readystate property.

    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        console.log(xmlhttp.status);
        document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
    }
