Headers.values

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

The Headers.values() method returns an iterator allowing to go through all values contained in this object. The values are ByteString objects.

Note: This method is available in Web Workers.

Syntax

headers.values();

Return value

Returns an iterator.

Example

// Create a test Headers object
var myHeaders = new Headers();
myHeaders.append('Content-Type', 'text/xml');
myHeaders.append('Vary', 'Accept-Language');

// Display the values
for (var value of myHeaders.values()) {
   console.log(value); 
}

The result is:

text/xml
Accept-Language
