MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

XMLHttpRequest.responseText

Draft
This page is not complete.

The XMLHttpRequest.responseText property returns a DOMString that contains the response to the request as text, or null if the request was unsuccessful or has not yet been sent. The responseText property will have the partial response as it arrives even before the request is complete. If responseType is set to anything other than the empty string or "text", accessing responseText will throw InvalidStateError exception.

Example

var xhr = new XMLHttpRequest();
xhr.open('GET', '/server', true);

// If specified, responseType must be empty string or "text"
xhr.responseType = 'text';

xhr.onload = function () {
    if (xhr.readyState === xhr.DONE) {
        if (xhr.status === 200) {
            console.log(xhr.response);
            console.log(xhr.responseText);
        }
    }
};

xhr.send(null);
