XMLHttpRequest: responseText property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers, except for Service Workers.
The read-only XMLHttpRequest property
responseText returns the text received from a server
following a request being sent.
Value
A string which contains either the textual data received using the
XMLHttpRequest or "" if the request failed or if no content has been received yet.
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
InvalidStateErrorDOMException-
Thrown if the
XMLHttpRequest.responseTypeis not set to either the empty string or"text". Since theresponseTextproperty is only valid for text content, any other value is an error condition.
Examples
const xhr = new XMLHttpRequest();
xhr.open("GET", "/server", true);
// If specified, responseType must be empty string or "text"
xhr.responseType = "text";
xhr.onload = () => {
if (xhr.readyState === xhr.DONE) {
if (xhr.status === 200) {
console.log(xhr.response);
console.log(xhr.responseText);
}
}
};
xhr.send(null);
