Menu.js. Uncaught Typeerror: Cannot Set Property 'className' Of Null
Nov 15, 2011
I've been using this javascript (menu.js) for a drop down navigation menu for my site. Everything works well on it but in multiple browsers I get this error occurring on line 7 and 16 which is the d.className = "menuHover"; and d.className = "menuNormal";
What i'm trying to accomplish is two things. To select the page i want to load in each tab then select how many of thoughs tabs i wish to open. When the number of tabs is selected i want it to launch. i also have a refresh button that works i just can't get the windows to load. by the way for this project i want it to open the same url that is selected on all of the tabs. Here is what i have:
I have a jQuery script which works fine online, but when it comes to testing locally I get this error on the 2nd line of code: Uncaught TypeError: Cannot call method 'hide' of null So, that means I'm trying to call a method on something that doesn't exist, or is set to null. But I'm trying to call the method on anything with the class menu. And there are divs with the class menu on my page. The script runs fine on several other pages, so it must have something to do with this page in particular, but I have no idea why...
I've put up the page online, but I don't have a direct link to it because it's a live site. You can see the code working here: The Pilot, and the offending page is here: The Gallery.
I have a page which has some content that is generated via an AJAX request and JSON. The content is shown and hidden by clicking on each row using the (Animated Collapsible DIV v2.4 script ). It works fine if I have the page as one static file (which I did for testing) showing the same content the AJAX pulls. But when I display the page with AJAX generated content it comes through and the source code is essentially the same but my show/hide effects are not working. I am getting an error when I troubleshoot using Google Chrome Developer Tools that says: Uncaught TypeError: Cannot read property '$divref' of undefined. I tried switching the order of the Javascript and HTML to see if that was the problem. But I think it has something to do with the way the page is loading in the AJAX based version. I looked into using the JQuery LiveQuery plugin but I could not figure out how to make it work with my code nor do I know if it is the fix I need anyways.
I have the following JQuery code: $("#menu-247 > a, #menu-213 > a, #menu-214 > a, #menu-215 > a, #menu-216 > a, #menu-218 > a, #menu-219 > a").addClass("mainLevel"); /*$(".mainLevel").each(function (i) { $(this).before('<div id="' + $(this).parent().attr("id") + '-behind"> </div>'); $(this).prev().css({ width: $(this).css("width"), height: $(this).css("height"), position: "absolute", top: "0", left: $(this).parent().css("left"), zIndex: "5", display: "none", backgroundColor: "blue" }); $(this).css({ position: "relative", zIndex: "10" }); });*/ $(".mainLevel").hover(function() { alert('test'); });
And I receive the error "Uncaught TypeError: Cannot read property 'guid' of undefined" in Google Chrome. I thought it had to do with the fact that the event handler was trying to be added before the DOM was modified. But then I tried simply this: $("#menu-247 > a, #menu-213 > a, #menu-214 > a, #menu-215 > a, #menu-216 > a, #menu-218 > a, #menu-219 > a").hover(function() { alert('test'); });
And still received the error. I removed all the "> a" so I simply had a list of ids and the error was still there. Even when I only have one id listed, the error comes up! It also seems to be any element. But if I just try the alert part, everything works.
i have a top navigation bar with a clickable down arrow. once clicked a drop-down will appear. there are about 5 to 6 click downs. the content in the click downs are store in an external html file and i use an iframe to display it. so if 1 arrow is clicked content will show and if another is clicked while the 1st stays open, it should replace the 1st one. <snip/> I am getting an error that says TypeError: Cannot read property 'style' of null. the code line it's referring to is the one below with the stars:
I got this simple test page linked here that is suppose to automatically "click" a box at load time. Works in all browsers, except for Chrome and Safari (webkit browsers). I'm getting the error ... Code: Uncaught TypeError: Object #<HTMLDivElement> has no method 'click' Do a "view source" and you will see all the code there as being ...
I have been trying to figure this out all day/night. And I have exhausted all my ideas....
so heres whats happening:
Ajax.js: varrequest = new XMLHttpRequest(); var response; var currentHeadLineItem = 0; iterator for which <li> node we select from our xml document response var lengthOfHeadLineList = 0; Review the offsett for this!!!!
I am having a problem with my jQuery. I am trying to get a plug-in called SlideDeck to work but the accordion will notslide. I found that jQuery is getting this Uncaught TypeError: Object #<an Object> has no method 'swing' on line 155. Everytime I click a slide to slide the repeat count goes up. Why I would be getting this error? I am using the enque script from wordpress and I am using jQueryopposedto the $ sign. Every other jquery code works fine.
This seems like a noob error, but I really googled it out, with not much results. Got stuck on just grabbing the XML. I validated the code with the w3.org validator and it's only missing a doctype. I've checked that the file is saved with no bom. It's served from my local Apache installation.
The error I get is:
With Firebug I got:
The jQuery code:
The headers look ok to me.Response Headers
I simplified the XML and just put it in a file, but the same error comes up even when the XML is generated with PHP. I did try to change the MIME type in the request and the response, but it's all the same.
Also, if I serve a file I get a 206, and a 200 response code for the same XML generated through PHP (using header("Content-type: text/xml")).
It should not be a cross-domain issue, as it's loaded and served from my localhost?
I did implement my script first for IE8 (sidebar gadget) without jQuery and works nicely with my PHP generated XML. Then I decided to pick up jQuery and hit the first wall head on.
I just got this script for a countdown on a website and I got it to work locally but when I upload it to the server i get the error "index.html:22 Uncaught TypeError: Object [object Object] has no method 'fancycountdown'".
I have checked to make sure all other javascript files are loading and they are and I can't figure out whats wrong. You can see it [URL]
I have a script that slideshows 5 images. Below the images is a numbered list; 1-5. I'd like to set the style of the number buttons based on the image being displayed as the images scroll from one to the next. Code:
the error goes like this:Cannot read property 'events' of null.I would like to be able to provide more details, but I'm truly lost here, the calling function is this one:[code]This code is using the GeoExt Library plus open layers, but the error seems to be related to another reason non-related to the libraries.
I am using a script called ajax_load.js that defines a function, ajaxpage(), that allows a person to load the contents of an external page into a div item. I have it setup so I may use ajaxpage() to load pages with other div items in it. The problem is that I cannot reference the div items loaded by ajaxpage(). I have provided an example below to illustrate this. It was working fine in the prior version of Google Chrome and is still working fine in IE 8, IE 7, and Firefox. The version of Chrome I am currently using is 4.0.249.78
Here is the example; All the files used in this example are listed below:
This code was working just fine in the prior stable version of chrome, and still works properly in IE 8, IE 7, and Firefox without any errors (The version of chrome giving me problems is 4.0.249.78). Does anyone know how to go about fixing this? Is this something wrong with the latest version of chrome, or is this on my end? The site I am currently working on relies heavily on this working, and having to change things means altering several thousand lines of code.
Lots of submenus and such, and just can't get this going. Works fine if I remove the submenu aspects of the script, however with these, it returns the error: uncaught exception: Syntax error, unrecognized expression: #
I'm trying to get rid of some javascript errors related to fadein/fade out. If you go to my test site here [url]... you will see the green ticks and red warning boxes working fine when entering information, but I get 92 (!) errors when checking the error console. [code]...
I have added some style="opacity:1; background: white;" properties to my HTML thinking that was the problem, but it makes no difference. Still getting the error related to line 124.
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines
I'm trying to usethisplugin (I've also tried the derivative bsmSelect) and can't seem to get it working.I have jQuery, the plugin .js, and my page .js all included, but on my page .js I get the error
"TypeError: Result of expression '$kuj("select[multiple]").bsmSelect' [undefined] is not a function."
This is while doing var $kuj = noConflict(); earlier, and here is my page .js.
