XMLHttpRequest
property
responseText
returns the text received from a server following a request being sent.
var resultText = XMLHttpRequest.responseText;
A
DOMString
which contains either the textual data received using the
XMLHttpRequest
or
null
if the request failed or
""
if the request 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
)，和
status
becomes 200 (
"OK"
).
InvalidStateError
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.
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);
