browser.msie error after update to jQuery 1.9.1
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?
Solution 1:
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 );
}

However, the reason that its deprecated is because jQuery wants you to use feature detection instead.
An example:
$("p").html("This frame uses the W3C box model: <span>" +
jQuery.support.boxModel + "</span>");
And last but not least, the most reliable way to check IE versions:
// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}
// And to detect the version:
// ie === 6 // IE6
// ie > 7 // IE8, IE9 ...
// ie < 9 // Anything less than IE9
// ----------------------------------------------------------
// UPDATE: Now using Live NodeList idea from @jdalton
var ie = (function(){
var undef,
v = 3,
div = document.createElement('div'),
all = div.getElementsByTagName('i');
while (
div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',
all[0]
);
return v > 4 ? v : undef;
}());
Solution 2:
$.browser was deprecated in version 1.3 and removed in 1.9
You can verify this by viewing the documentation.
Solution 3:
For simple IE detection I tend to use:
(/msie|trident/i).test(navigator.userAgent)
Visit the Microsoft Developer Network to learn about the IE useragent: http://msdn.microsoft.com/library/ms537503.aspx
Solution 4:
The jQuery.browser options was deprecated earlier and removed in 1.9 release along with a lot of other deprecated items like .live.
For projects and external libraries which want to upgrade to 1.9 but still want to support these features jQuery have release a migration plugin for the time being.
If you need backward compatibility you can use migration plugin.
Solution 5:
Update! Complete answer overhaul for new plugin!
The following plugin has been tested in all major browsers. It makes traditional use of userAgent string to re-equip jQuery.browser only if you're using jQuery version 1.9 or Greater!
It has the traditional jQuery.browser.msie type properties as well as a few new ones, including a .mobile property to help decide if user is on a mobile device.
Note: This is not a suitable replacement for feature testing. If you expect to support a specific feature on a specific device, it's still best to use traditional feature testing
