Navigator.vendorSub

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

The Navigator.vendorSub read-only property is the substring of the vendor having to do with the vendor version number. The specification allows browsers to always return the empty string, so don't rely on this property to get a reliable answer.

Syntax

venSub = window.navigator.vendorSub

Value

venSub is a DOMString.

Example

window.navigator.vendorSub 
// returns "6.1" where the vendor part of userAgent is 
// Netscape6/6.1

Notes

vendorSub is a component of the full user agent string. It refers to the version number that the vendor themselves have given the current browser (as opposed to the version of the product, which may be different). In Netscape 6.1, the productSub is given as "5.0" and the vendorSub is "6.1." See also navigator.productSub, navigator.userAgent, navigator.vendor
