$browser not defined

I am trying to use jquery for browser detection but it says

Uncaught ReferenceError: $开发者_如何学JAVAbrowser is not defined

the code is like

if(!$browser.msie){
   condition
 }

$.browser was removed in jquery 1.9. See http://jquery.com/upgrade-guide/1.9/#jquery-browser-removed

browser is a property on the main jQuery object: if(!$.browser.msie){ ... }

Please note that since the time of posting, this property has been removed in jQuery 1.9.

$browser is not defined because the browser property is defined as a part of the jQuery (or $) object.

In other words, use $.browser or jQuery.browser, not $browser.

Try

$.browser.msie

or

jQuery.browser.msie

You are missing a dot:

$.browser

Check out the documentation.

It's $.browser, not $browser

if($.browser.msie) ...
