jQuery.browser: Javascript Uncaught TypeError

Question

I'm experiencing an error which wont let my page load.

Uncaught TypeError: Cannot read property 'msie' of undefined

The error in the console refer to this code:

if (jQuery.browser.msie)
    extra_px += 3;
                                                   // Fix Link Clicking on IE 7 and below versions
if (jQuery.browser.msie && Number($.browser.version) < 8) {
    span_text.css('cursor', 'pointer');
    span_text.click(function() {
        window.location = menu_item.parent().attr("href");
    });
}

The weird thing is that it suddenly happened, I didn't change a thing. For reference, I'm using Wordpress.

Solution 1

jQuery.browser was deprecated in version 1.3, and finally removed in 1.9.

_source

As you can see in current version of jQuery, there is no $.browser property anymore.

Most probably it was moved to plugin as was stated in docs.

So if you use the very last version of jQuery, the undefined error is understandable.

Solution 2

Yes, jQuery.browser was deprecated in older version and removed in 1.9.So Now In old version if code written like this

isIE6 = jQuery.browser.msie && jQuery.browser.version < 7 && !window.XMLHttpRequest,

will be replaced it by

isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,

Cheers!!!

Solution 3

As VisioN's answer mentions, this was removed in jQuery 1.9 and isn't coming back anytime soon, it seems.

If you would like working Plugin to reAdd $.browser to your jQuery library, simply copy & paste the code below to a file and link the script in anywhere after jQuery:

;;(function($){if(!$.browser&&1.9<=parseFloat($.fn.jquery)){var a={browser:void 0,version:void 0,mobile:!1};navigator&&navigator.userAgent&&(a.ua=navigator.userAgent,a.webkit=/WebKit/i.test(a.ua),a.browserArray="MSIE Chrome Opera Kindle Silk BlackBerry PlayBook Android Safari Mozilla Nokia".split(" "),/Sony[^ ]*/i.test(a.ua)?a.mobile="Sony":/RIM Tablet/i.test(a.ua)?a.mobile="RIM Tablet":/BlackBerry/i.test(a.ua)?a.mobile="BlackBerry":/iPhone/i.test(a.ua)?a.mobile="iPhone":/iPad/i.test(a.ua)?a.mobile="iPad":/iPod/i.test(a.ua)?a.mobile="iPod":/Opera Mini/i.test(a.ua)?a.mobile="Opera Mini":/IEMobile/i.test(a.ua)?a.mobile="IEMobile":/BB[0-9]{1,}; Touch/i.test(a.ua)?a.mobile="BlackBerry":/Nokia/i.test(a.ua)?a.mobile="Nokia":/Android/i.test(a.ua)&&(a.mobile="Android"),/MSIE|Trident/i.test(a.ua)?(a.browser="MSIE",a.version=/MSIE/i.test(navigator.userAgent)&&0<parseFloat(a.ua.split("MSIE")[1].replace(/[^0-9\.]/g,""))?parseFloat(a.ua.split("MSIE")[1].replace(/[^0-9\.]/g,"")):"Edge",/Trident/i.test(a.ua)&&/rv:([0-9]{1,}[\.0-9]{0,})/.test(a.ua)&&(a.version=parseFloat(a.ua.match(/rv:([0-9]{1,}[\.0-9]{0,})/)[1].replace(/[^0-9\.]/g,"")))):/Chrome/.test(a.ua)?(a.browser="Chrome",a.version=parseFloat(a.ua.split("Chrome/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/Opera/.test(a.ua)?(a.browser="Opera",a.version=parseFloat(a.ua.split("Version/")[1].replace(/[^0-9\.]/g,""))):/Kindle|Silk|KFTT|KFOT|KFJWA|KFJWI|KFSOWI|KFTHWA|KFTHWI|KFAPWA|KFAPWI/i.test(a.ua)?(a.mobile="Kindle",/Silk/i.test(a.ua)?(a.browser="Silk",a.version=parseFloat(a.ua.split("Silk/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/Kindle/i.test(a.ua)&&/Version/i.test(a.ua)&&(a.browser="Kindle",a.version=parseFloat(a.ua.split("Version/")[1].split("Safari")[0].replace(/[^0-9\.]/g,"")))):/BlackBerry/.test(a.ua)?(a.browser="BlackBerry",a.version=parseFloat(a.ua.split("/")[1].replace(/[^0-9\.]/g,""))):/PlayBook/.test(a.ua)?(a.browser="PlayBook",a.version=parseFloat(a.ua.split("Version/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/BB[0-9]{1,}; Touch/.test(a.ua)?(a.browser="Blackberry",a.version=parseFloat(a.ua.split("Version/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/Android/.test(a.ua)?(a.browser="Android",a.version=parseFloat(a.ua.split("Version/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/Safari/.test(a.ua)?(a.browser="Safari",a.version=parseFloat(a.ua.split("Version/")[1].split("Safari")[0].replace(/[^0-9\.]/g,""))):/Firefox/.test(a.ua)?(a.browser="Mozilla",a.version=parseFloat(a.ua.split("Firefox/")[1].replace(/[^0-9\.]/g,""))):/Nokia/.test(a.ua)&&(a.browser="Nokia",a.version=parseFloat(a.ua.split("Browser")[1].replace(/[^0-9\.]/g,""))));if(a.browser)for(var b in a.browserArray)a[a.browserArray[b].toLowerCase()]=a.browser==a.browserArray[b];$.extend(!0,$.browser={},a)}})(jQuery);

Use traditionally like: if ($.browser.msie) { doWork }

OP shouldn't include the latest version but a specific version

[John Dvorak]

@ExplosionPills and yet he likely does

[Explosion Pills]

@JanDvorak he does; I looked at his website's code. He includes 1.8.3 via wordpress, but then he also includes a link to the jQuery cdn for the latest version

[TonalDev]

The 1.8.3 file breaks thing so i had to include the latest for things to work..i still havent found the location from which the devloper loaded the file.

[John Dvorak]

1.8.3 is the latest version

[TonalDev]

VisioN answer was correct...i referred to the 1.8.3 Ver'...and it worked.

[Explosion Pills]

@JanDvorak for whatever reason they updated the CDN to point to 1.9, but the other jQuery websites aren't updated (the documentation isn't and jquery.com still says the "current release" is 1.8.3).

[Charles Robertson]

a.browserArray[b].toLowerCase() throws an undefined error. If I take the .toLowerCase() out, it works!

[Charles Robertson]

Thanks anyway. Good job!
