jQuery error: Uncaught TypeError: Cannot use 'in' operator to search for 'backgroundColor' in undefined
You may be able to use the 'each' function of jQuery: $('.metro_menu_button').each(function() { $(this).data('oldColor', $(this).css('background-color')); }); The 'each' should run this for each matching node; your original would probably not have had the correct value for 'this'.

backbone.localStorage, require.js, "Uncaught TypeError: undefined is not a function"
The problem lies with the fact that the latest Backbone localStorage is AMD compatible, where as the version in that example is not, hence the shim config. The fix Remove the shim config for backbone.localStorage, you won't be needing it: 'backbone.localStorage': { deps: ['backbone'], exports: 'Backbone' } Then, in Todo.js change the define call from: define(['underscore', 'backbone.localStorage'], function(_, Backbone) { to: define(['underscore', 'backbone', 'backbone.localStorage'], function(_, Backbone) { Why? The shim exports config was being used to say 'When I ask for backbone.localStorage, return me Backbone'. This allowed 'backbone.localStorage' to be used simply as Backbone inside the Todo module. But now backbone.localStorage supports AMD and explicitly returns

jquery Uncaught TypeError: Cannot read property 'left' of undefined
Just a guess, but I suspect: currentPageItem = $('#active', nav), should be: currentPageItem = $('.active', nav), # is for selecting by ID, . is for selecting by class. Since IDs are unique, it doesn't make sense to search for a different active ID in each element, this is what classes are used for.

Why am I getting this error: Uncaught TypeError: cannot read property 'john' of undefined
As of the time that you're creating the object you're assigning to the suzie property, employees is undefined. The property initializers are evaluated before the overall expression is complete. Here's the order in which things happen above: The engine creates a variable called employees with the initial value undefined. The engine creates a blank object (which will eventually be assigned to employees). The engine creates another blank object (which will eventually become the john property value). It evaluates "John Smith" and creates a property on the blank object from #3 called name, giving it that value. It repeats that process for age, job, and greet. It assigns that object to the john property on the object from #2 above. It creates another blank object (to become suzie). It evaluat

jQuery Datatables: Uncaught TypeError: Cannot read property 'asSorting' of undefined
You do not call any asynchronous function (such as some AJAX calls) so the $.when function doesn't make sense here. As you use functions which will be called after the last one has completed the following code should work. var tableProgress; tableProgress = "<table id='table-progress'><tr><td></td></tr></table>"; $("#send-one").html('done.

Ember.js + AddThis error "Uncaught TypeError: Cannot read property 'call' of undefined "
I had a deeper look at the addthis widget and IMHO the code loaded from the script does some nasty things like creating a script tag nor an iframe etc. and being inside a handlebars template the DOM manipulations that the widget script does won't work in tandem with ember.js, unless the team behind addthis does something to make there widget more integration friendly. So I had a look at some alternative sharing widgets, and sharethis does basically the same as addthis but with one big difference - I got easily working with ember.js Basically what I've done was to create a view for the widget, and inside the didInsertElement the widget initialization is called: App.WidgetView = Ember.View.extend({ templateName: 'widget', didInsertElement: function() { stLight.options({publisher:

jQuery widget $.ajax() .abort() "Uncaught TypeError: Cannot read property 'length' of undefined"
Based on Kevin B's comments to my question, I used the stack trace in Chrome to get to the problem line of code. Fortunately it has nothing to do with the code that I posted in my question. It is related to a function that I have written to handle errors from the server. Calling xhr.abort() forces the error method of $.ajax() to be called. I have a function assigned to the error method that was looking at the xhr.responseText and I failed to check to see if xhr.responseText was not null and not undefined. I hope this helps someone else!

mercury-rails no editable area js error 'Uncaught TypeError: Cannot read property 'konqueror' of undefined '
I've found the problem and have solved it in the following way! It turns out that mercury is using the jquery method jQuery.browser, which is deprecated in the jquery 1.9 upgrade. I'm using gem 'mercury-rails', git: 'git://github.com/jejacks0n/mercury' so this will probably get fixed and I don't know how else to document if this solution is relevant to you, but this is the latest commit I'm using from the mercury gem, d065b2c31b895af03749254b521f0c0ee18fb25a. Including this gem solved the issue for me. gem 'jquery-migrate-rails' and don't forget //= require jquery-migrate-min in the application.js file, after requiring the other jquery files.

console error when using jquery - Uncaught TypeError: Object # has no method
When you access an item from a collection with a subscript like [i], you're actually unwrapping it from the jQuery object, and accessing a raw DOM node, which doesn't have methods like addClass and css. Use .eq() instead: var i = 0; $(".question").eq(i).addClass("show"); $(".question").eq(i).css("display", "block");

Preload images in jquery/canvas "Uncaught TypeError: Type error"
First of all, you need to pass an actual image element to the drawImage method. Now you're passing a deferred in. Next, there's a bug with Chrome and native elements constructor (new Image()). So, simply use document.createElement("img") which will do exactly the same thing - without the bug. See the related bugs: About Canvas: https://code.google.com/p/chromium/issues/detail?id=238071 The root cause: https://code.google.com/p/chromium/issues/detail?id=245296 I created a reduced example here: http://jsfiddle.net/YVDpD/

Uncaught TypeError: Cannot set property '0' of undefined
You have albumThumbnails and albumPhotos as empty arrays, and in the loop you are trying to add values into the array. let us take the case where i = 0 your array albumThumbnails has a length of 0 that means albumThumbnails[0] is undefined, then you are trying to set albumThumbnails[0][0] which is giving the error. The solution here is to first create an empty object at the index i if required then set its property Looks like you are trying to create the object here for(var k=0; k<numberOfPhotos && k < response.data.length; k++){ albumThumbnails[i] = albumThumbnails[i]||{}; albumThumbnails[i][k] = response.data[k].picture; albumPhotos[i] = albumPhotos[i] || {}; albumPhotos[i][k] = response.data[k].source; }

Uncaught TypeError with undefined in javascript
You are attempting to take the length of undefined (i.e., undefined.length), which is what is throwing the 'Uncaught TypeError' error. Clearly, $("#someInputId") is undefined or returns no results. Most likely, $("#someInputId") returned no results, and the value of an empty set is undefined. Your conditional check reaches the second clause because $() will always instantiate a jQuery object. But if the jQuery object is empty, its value will be undefined. To avoid this error, you need to check that your query returns a result: var varId = $("#someInputId"); if (varId.length > 0 && varId.val().length === 0) { That conditional will be true if #someInputId exists and has a value of 0.

jQuery Bootstrap: "TypeError: 'undefined' is not a function (evaluating 'jQuery('#myModal').modal('hide')')
it's late but i hope this helps. Make sure you're including the jQuery library before your custom script, and that there are no errors in the Net tab of Firebug (make sure jQuery actually gets loaded). Test your javascript code in firebug and when ready to add to your actual code you can call it as anounymous function: (function ($) { $(document).ready(function(){ //your code ('# id of the modal element to close ').modal('hide') }); //your code }(jQuery)); You can check this video link to tutorial, i think they have a good expose of debugging process.

Uncaught TypeError: Cannot read property 'r' of undefined
Your changed values in split() are not propagating back to your calling function comaprison() because the parameter varHolder is pass by value, not pass by reference. This means that any changes to the variable within the function are local to that function only. To get around this, you have to return the new variable to the outer function. varHolder = { r: colorArr[0], g: colorArr[1], b: colorArr[2], a: colorArr[3] } //The below log works. console.log('-----------Split-------') console.log(varHolder.r); return varHolder; } function comparision(){ lineObj = split(colorL,lineObj); console.log('---------get-------'); //This log doesn't work console.log(lineObj.r); } If this is your entire code, this can be simplified further by rem

This type of error mean that your container variable fileis not defined. You should use console.log at different places to see what is defined and what is not (your files array, etc.) Also : for(x=0;x<=this.files.length;x++) Will be undefined for the last x value, because the last element of an array is at array.length - 1and not array.length, that gives you an undefined value at the end of your loop, probably the source of your error. In your case, x goes to the value this.files.length Also, always use var, otherwise your xwill be a global variable, which can be another source of problems. A correct loop should be : for (var x = 0; x < this.files.length; x++)

Uncaught TypeError: Cannot set property 'unobtrusive' of undefined
In your bundle, you set it to include jquery.validate* and jquery.unobtrusive*, which would normally work. But if you look at your output, not all files that should be there are there. The point is that jquery.unobtrusive.validate requires jquery.validate to be included (which, as you can see, is not, by your output). Apparently, the files aren't actually available in your project, and therefore aren't found by the bundler. Make sure to have all necessary files in your project so your bundler can find them and output them.

A couple of things... You have not included the Admin store in your controller. store is required for a Tree, so if that reference is failing then that could be the issue. You are adding items to your tree in initComponent, which doesn't make sense. Your config for the tree is already in Ext.define, so setting this.items = ... is adding a new, nested item inside the tree panel. This is not what you want. As mentioned in my comment, don't use both alias and xtype in Ext.define. If you don't need any specific extra functionality added to your tree (which your current code suggests), and you are only using it once (not sure if this is the case), you could also just use a single instance of a tree without defining a separate class for it: { xtype: 'treepanel', store: 'Admin',
