I would like to expand upon the typeof operator.
Using 'typeof' I can distinguish between string and
array for instance, because typeof returns "object" for
array.
How can I programmatically distinguish between an Array and an Option,
for instance?
how to get the type/tagname of an object using its tabindex in jquery.

I have a image gallery that gives very nice popup windows when you click the thumbnail for the larger picture. The problem is that when you hover over the thumbnail(link) it doesn't change the cursor type to a hand which makes it hard to know that it's a link....
View 1 Replies View RelatedSo I've got a nested object that has this structure:
{"big_s":
{"s1":{"params":{"p1":"stuff","p2":stuff2"","p3":"stuff3"}},
"s2":{"params":{"p1":"stuff","p2":"stuff2","p3":"stuff3"}}
}
}
how would I go about removing one of the inner objects - s1 or s2? I've tried all sorts of ways but can't seem to get anything to remove an item from a jQuery object.
How can I avoid type-conversion (object variable --> string) when
passing an object variable to a function?
Example:
-->
catch(myerrorobject)
alert(myerrorobject.filename);
{
my_function('bla: ',myerrorobject);
}
<---
I get the "myerrorobject.filename" in the alert-Box, but I get an
"undefined"-error, if I try to access myerrorobject.filename (or other
properties) in the function "my_function". Why?
I'm apparently misunderstanding what I'm reading on prototyping. My main task is to squeeze some performance out of an app that's a bit slow on IE, and it looks like large Arrays and their overhead may be part of the problem. I'm trying to replace those with my own array type based on Object and extend it with helper functions like .length. Here's a munged sample of what I've tried:

Is there any way to find a string representing an object's class,
which will work in Internet Explorer 6?
"typeof" doesn't work -- it returns "object" for all objects:
x = window.open('http://www.yahoo.com/');
alert(typeof x);
And I found this page:
http://www.mozilla.org/js/language/...xpressions.html
which claims: "To get the type of an object x, use x.class".
However, that doesn't work in IE 6 so it must be Mozilla-only.
I need to add an event for all elements that are not text entry.I have tried this
$(':not(input:text, input:textarea)')
$(':not(:text, :textarea)')
I tried to get it to work for just not type=text
$(':not(:text)')
$(':not(input:text)')
I can't seem to figure it out.
I have to change text input type to password input type and i am using jquery script. This script work for FF, Chrome and Safari browser but not worked on ie7, ie8.

The javascript function addRowToTable() is called by a button, and replies a set of elements (select, input, checkbox) of the form.In this function, the creation of select calls another function CliK(sel.id)The problem is that this function tells me error "object required" as if the select Id was not "type" or the checkbox id was not "key"Where I go wrong?Posting the complete code
function addRowToTable()
{
var tbl = document.getElementById('tblSample');

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 the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
13 line causes this exception. Function is called insied of ready() handler. function renderGridSystemRecursively(scheme, container){

I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId)
{
alert(typeof document.getElementById(formId)); // object always
alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken

Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?
every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
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 am using a Photo Gallery script called Galleria which uses jQuery/JavaScript to display photos. On my index page load (only in Internet Explorer), a message box pops up saying "Message from Web Page [object Object]". After clicking OK the photo gallery loads and there is no problem.No idea how to fix this, or really what the error means. You can view the error from my site here
View 3 Replies View RelatedI am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
I created a method for displaying an object's properties:
As long as renderfunction = false, the object is fine coming out of this function.
However, if I change renderfunction to true, all my properties become undefined. Why isn't this working as I expect it to?
How would I go about copying all the prototype functions AND the constructor from one object into another object, and then call them?
I know I can use this.example.call(this), but that's not an acceptable solution. I want to deploy this style over dozens, potentially hundreds of objects.
I am trying to alert the ID of a particular menu that I have clicked on and I am getting object,object. Instead of the name of the ID.

I have two result. SelectableChildren: groupHead.nextAll(".SimpleButton") and SelectableChildren: groupHead.nextAll(".SimpleButton").next().children(".SimpleButton")
I would like to combine them into one object so that I can bind a handle to them in one loop. $.each(combineResult, function(index, object){ ... })
I have to make them in one, so that I can pass it around.
I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.
<script>
//This is an example of a problem im having in my own code...
//I want to access the name of the object within the links array wintin the object...

I've been trying to create a 'loading page' for a from. When a user submitts a form, a loading animation is displayed on the page. Then I have javascript connecting to a url on my server that generates a dynamic file and returns it from memory. My problem is that I can display the text from this new file, but what I want to do is prompt the user to save the file locally. Is there a way to make this sort of conversion in javascript?
