XMLHttpRequestResponseType type is an enumerated set of strings which are used to specify the type of data contained in the response of an XMLHttpRequest . These values are used when getting or setting the responseType on the request.

值

""

空 responseType string is treated the same as "text" , the default type.

arraybuffer

response is a JavaScript ArrayBuffer containing binary data.

blob

response 是 Blob object containing the binary data.

document

response 是 HTML Document or XML XMLDocument , as appropriate based on the MIME type of the received data. See HTML 在 XMLHttpRequest to learn more about using XHR to fetch HTML content.

json

response is a JavaScript object created by parsing the contents of received data as JSON .

text

response is a text in a DOMString 对象。

ms-stream

response is part of a streaming download; this response type is only allowed for download requests, and is only supported by Internet Explorer.

Deprecated values

moz-chunked-arraybuffer

A Firefox-only value which instructs XMLHttpRequest to deliver ArrayBuffer objects containing chunks of the incoming data. Accessing response during a progress event returns the data received so far. Outside the progress event handler, the value of response is always null . You shouldn't use this non-standard (and, as of Firefox 68, entirely removed) API; instead, consider using the Fetch API with readable streams , which offers a standard alternative to accessing the response in a streaming fashion.
