What's the replacement for $.browser

Question

The jQuery document tags $.browser as deprecated. So what's the replacement for it?

Answer 1

Based on jQuery migration plugin , I found this.

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"
    };
};
if ( !jQuery.browser ) {
    var 
    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;
}
