$.browser is undefined - jquery type error

This browser function removed from jquery version 1.9. you need to write code for this or include jquery migrate plugin to restore depreciated functions

Method 1:
Write code to support this function and attach to jquery like this:

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;
