      Returns any

onreadystatechange

onreadystatechange: (ev: Event) => any

Type declaration

Readonly readyState

readyState: number

Returns client's state.

Readonly response

response: any

Returns the response's body.

Readonly responseText

responseText: string

Returns the text response.

Throws an "InvalidStateError" DOMException if responseType is not the empty string or "text".

responseType

responseType: XMLHttpRequestResponseType

Returns the response type.

Can be set to change the response type. Values are: the empty string (default), "arraybuffer", "blob", "document", "json", and "text".

When set: setting to "document" is ignored if current global object is not a Window object.

When set: throws an "InvalidStateError" DOMException if state is loading or done.

When set: throws an "InvalidAccessError" DOMException if the synchronous flag is set and current global object is a Window object.

Readonly responseURL

responseURL: string

Readonly responseXML

responseXML: Document

Returns the document response.

Throws an "InvalidStateError" DOMException if responseType is not the empty string or "document".

Readonly status

status: number

Readonly statusText

statusText: string

timeout

timeout: number

Can be set to a time in milliseconds. When set to a non-zero value will cause fetching to terminate after the given time has passed. When the time has passed, the request has not yet completed, and the synchronous flag is unset, a timeout event will then be dispatched, or a "TimeoutError" DOMException will be thrown otherwise (for the send() method).

When set: throws an "InvalidAccessError" DOMException if the synchronous flag is set and current global object is a Window object.

Readonly upload

upload: XMLHttpRequestUpload

Returns the associated XMLHttpRequestUpload object. It can be used to gather transmission information when data is transferred to a server.

withCredentials

withCredentials: boolean

True when credentials are to be included in a cross-origin request. False when they are to be excluded in a cross-origin request and when cookies are to be ignored in its response. Initially false.

When set: throws an "InvalidStateError" DOMException if state is not unsent or opened, or if the send() flag is set.
