browser msie error after update to jQuery 1 9 1

0 votes

I use the following snip of a script:

if ($.browser.msie && $.browser.version < 9) {
   extra = "?" + Math.floor(Math.random() * 3000);
}

It works fine with jQuery 1.8.3.

Now I updated jQuery to the new version 1.9.1 to use a new script.
Now I get the following error:

TypeError: Cannot read property 'msie' of undefined

I read the change log of the new jQuery version, but nothing should have changed
with msie

Any known bugs, tips or proposals?

Since $.browser is deprecated, here is an alternative solution:

/**
 * Returns the version of Internet Explorer or a -1
 * (indicating the use of another browser).
 */
function getInternetExplorerVersion()
{
    var rv = -1; // Return value assumes failure.

    if (navigator.appName == 'Microsoft Internet Explorer')
    {
        var ua = navigator.userAgent;
        var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
            rv = parseFloat( RegExp.$1 );
    }

    return rv;
}

function checkVersion()
{
    var msg = "You're not using Internet Explorer.";
    var ver = getInternetExplorerVersion();

    if ( ver > -1 )
    {
        if ( ver >= 8.0 ) 
            msg = "You're using a recent copy of Internet Explorer."
        else
            msg = "You should upgrade your copy of Internet Explorer.";
    }

    alert( msg );
}
