The read-only XMLHttpRequest property responseText returns the text received from a server following a request being sent.

Syntax

var resultText = XMLHttpRequest.responseText;

Value

A DOMString which contains either the textual data received using the XMLHttpRequest or null if the request failed or has not yet been sent by calling send().

While handling an asynchronous request, the value of responseText always has the current content received from the server, even if it's incomplete because the data has not been completely received yet.

You know the entire content has been received when the value of readyState becomes XMLHttpRequest.DONE (4), and status becomes 200 ("OK").

Exceptions

InvalidStateError
The XMLHttpRequest.responseType is not set to either the empty string or "text". Since the responseText property is only valid for text content, any other value is an error condition.

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);
