Is there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.
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 am trying to read all the navigator object elements
1. Using the navigator.length returns undefined, cant use for loop;
2.Using and array of known elements like var a = Array("appCodeName","appName","appVersion"); I seem to miss something to get it combined like navigator.a[i]
I have something that's called with AJAX when the user enters some text [url]. What I want is to execute some javascript within this "frame". If the frame calls something, with say <script type="text/javascript"> document.write('h'); </script> in it, then "h" doesn't appear, and neither does anything besides what would normally be shown if I didn't add that.
I'm creating a popup to display a loading message, inside this popup i placed an animated gif...the problem is that the gif is not being animated (it is an animated gif...) , its is being shown but without the animation...
This is the code:
oPopupLoading = window.createPopup(); var oPopupBody = oPopupLoading.document.body; oPopupBody.style.cssText = "margin:0px;border:1px outset;background:#97baea;FONT-FAMILY: verdena, Arial, sans-serif;overflow:hidden" var hStr = "";
I have a complex JS object. It manipulates the page DOM. Inside it I have many repetitive selections spread across functions. I would like to cache the selectors to enhance performance. How do other people do this? I can cache on the function level but not the object. When I try to cache on the object level I seemingly end up with stale selectors that while defined don't actually work.
My gut is that I can only cache on the function level?
what I have read does not deal with caching inside a JS object.
function JGallery(){ this.name="defaultGallery"; this.images=[{//some JSON here}] this.render=function(){

I've tried to debug it in firebug, but I guess there is a problem with the scope of the 'this'. The 'this' in
//i want append div with id of the name property of jgallery class $("<div></div>").appendTo("#container").attr("id",this.name); seems to refer to the iterator in the $.each().
I've tried to do this.this.name but it still doesn't work. Is there any way to allow me access the property of the Jgallery class?
I'm trying to use jQuery to get the two-letter country abbreviation from a URL that does exactly this. You give the URL your IP address, and it spits you back the string. Try it: [URL] When I try to get this to display on my page using jQuery, however, all I am getting back as the "data" is "[object XMLHtttpRequest]". I am thinking this has something to do with the fact that it's not coming back as HTML? It's just "US" as a plain text string. Does this make a difference? Here's my code:
I am trying to implement the PowerZoom script inside of FancyZoom. The scripts work fine when called separately, but if I try to call PowerZoom inside of the FancyZoom object nothing happens. I get no errors from the pages and the console is clean.Is it possible to call a function from a dynamic object? Here is a test page to see what I'm trying to do.
How do I store an object reference inside a variable when I want the object reference to to reference the first "ul" html element nested inside the current object (as referenced by this keyword)?
jQuery.fn.checkBoxTableHighlighter = function(){ return this.each(function() { var $obj = $(this);[code]....
When the check box is checked (onload, click or keyup), if the table has a specified selector then i want to change the background color. I already have a working sample that i am converting to plugin. Since, my selector is at the table level, how can i find the checkboxes that are inside tr and td?
I know I can use the functions like parseFromString() to access and modify an existing XML documents, but is it possible to use JavaScript to create a blank xml document?
I want to take data entered into the client, package it up as XML and use ajax to transmit it to the server. So far I've written my own class to create a simple xml document, but I'd like to do it properly with the inbuilt functions.
Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work: var arguments=new Object(); arguments['ticket']=ticket; arguments['email']=email; arguments['module']=module; arguments['epoch']=new Date().getTime();
var total=0; $('select.category').each(function(){ var name=$(this).attr('id'); var option=$(this).find('option:selected').val(); total+=parseInt(option); arguments[name]=option; });
The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like a variable scope issue or something. If I put some extra debug code to print out all the property/value pairs, outside each loop I only see original four, and inside each loop only the new one just set and none of the original four.?
Is it possible to test whether two objects are equal using the data they contain inside and not comparing their pointers with ==?
Well actually of course there is but...
Is there a way to do it without actually looping through the object, instead maybe something that came with JS? (something like a .equals() method from other programming languages.)
Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).
The code is like so: Code: function myobject(params){ //public this.initialize = function(){...} //private some variables... //problem variable var mouse = new Object() mouse.x = 0; mouse.y = 0;
//this function is in an interval function moveslides() { /* this is where I have the problem
It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it? */if(mouse.x) { code... }}} The page is at [URL] and works on every browser, including finnicky opera, except for ie. The full code is availabe when you right click and view the source on the page.
Can anyone suggest how to create an arbitrary object at runtime WITHOUT using the deprecated eval() function. The eval() method works ok (see below), but is not ideal.
function Client() { } Client.prototype.fullname = "John Smith"; var s = "Client"; eval("var o = new " + s + "();"); alert(o.fullname);
Note: I want the type name of the object to be represented as a string (in this case "Client" -- this is a non-negotiable requirement).
I also tried the following (which appears to fail):
function Client() { } Client.prototype.fullname = "John Smith"; var s = "Client"; var o = new Object(); o.construct = s; alert(o.fullname);
eval() is handy but not future-proof, so any suggestions would be welcome.
