Just put below the $.browser code in your js

var matched, browser;

jQuery.uaMatch = function (ua) {
ua = ua.toLowerCase();

var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
/(webkit)[ \/]([\w.]+)/.exec(ua) ||
/(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
/(msie) ([\w.]+)/.exec(ua) ||
ua.indexOf(“compatible”) < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) ||
[];

return {
browser: match[1] || “”,
version: match[2] || “0”
};
};

matched = jQuery.uaMatch(navigator.userAgent);
browser = {};

if (matched.browser) {
browser[matched.browser] = true;
browser.version = matched.version;
}

// Chrome is Webkit, but Webkit is also Safari.
if (browser.chrome) {
browser.webkit = true;
} else if (browser.webkit) {
browser.safari = true;
}

jQuery.browser = browser;
