XMLHttpRequest.overrideMimeType

The XMLHttpRequest.overrideMimeType() method overrides the MIME type returned by the server. This may be used, for example, to force a stream to be treated and parsed as text/xml, even if the server does not report it as such. This method must be called before send().

Syntax

XMLHttpRequest.overrideMimeType(DOMString mimetype)

Parameters

mimetype - a string of the file type

Return value

Nothing. It doesn't return anything.

Example

// if the server doesn't specify, the returned text gets treated like xml
// and when you receive plain text or something instead of xml 
// you get an error: XML Parsing Error: not well-formed

// this shows how to receive plain text
req = new XMLHttpRequest()
req.overrideMimeType("text/plain")
req.addEventListener("load", callback)
req.open("get", url)
req.send()
