How do I get the childelements of a div, but only the child elements that are "ahref" tags?
for example:
<div id="someDivID">
<a href="somepath.html">link 1</a>
<a href="somepath.html">link 2</a>
[code]...
I want all the childElements under someDivID that are "a href" types...I am using prototype: I figured the following would work, but didn't.
$('someDivID').childElements.getElementByTagName('a')
JavaScript hides its memory structure.
I know that numbers, booleans, null and undefined are value types
(value is directed saved in a variable).
I want to know:
- How JavaScript distinguishes value types from reference types by
seeing the variable content?
- How many bytes are allocated in memory when I declare the following?
var i;
I can program in JavaScript without understanding them.
But I'm curious.
OK, simple script that currently takes an array of ID values (hard coded) and then iterates through them to fade in and out creating a slideshow.
The obvious problem is I have to hard code the number of DIVs in the slideshow. What I really want is the code to get the child elements of the container I pass it and then iterate through them dynamically.
[Code]...
function aa() {};
var bb = new aa();
var dd = new function cc() {};
aa.prototype.rr = 100;
cc.prototype.rr = 100;
---------------------------------------------------------------
i wrote the code above that makes two functions and two object for
those.
bb(object)<-aa(function),
cc(object)<-dd(function).
i think it's all the same way to make an object for a function.
but if u try to debug,
bb object has rr right after "aa.prototype.rr = 100" statement
but cc deosn't have rr variable.
can anyone explain it why?

This pice of code is dynamically created by my shopping carts admin section which is an attribute for a certain product.
The problem I have is that all the attributes are displayed in an array and positioning each is not possible (well, I have posted a query in another forum with regards to that). I have taken the code, as viewed in the source code, and added it in where I please e.g. radio buttons, checkboxes etc, which function perfectly.
This does make 'duplicate' field but I have used display:none on the generated code which hides it. I have found a snippet of code which fixes issues will type=text fields....
But this can not be done when it comes to type=file.
Once you browse and select your image, i need the directory to be entered into the 'real' field for uploading when submitted.
How do i restrict files types that can be accessed when using the input element type file...like the one used when uploading..how do i restrict it to certain files with given file extensions?

Since IE 6 doesn't recognize type selectors in css (input[type=xxx] {}) I'm adding classes to elements dynamically so I have handles for the different types of <input/> elements.Here's what I'm using, but it feels sloppy (maybe not the most efficient approach?). Is there a better/less verbose/more efficient way to do this?
$('input')
.filter('[type=text]').addClass('input_text').end()
.filter('[type=radio]').addClass('input_radio').end()

Can I find multiple objects in one call? For example, I have ahold of a TD object that has in it input and select objects. I want to addClass to both the input and select objects therein? Something like ".find('input || select')"? Otherwise I guess I could just do multiple calls similar to:
//First find all of the required elements indicated by the red *

Basically I have an text field with an id of s_username As the user types I want to append this to a var so I can display what the user has entered at the side of the screen, I have been using this for select boxes:
var ramCost = $("#ram").val();
what I want to do is have an auto suggest of words as a user types, the code that I have works only once.For example: if you type.. hel, it will suggest hello but once you press space and type hel, again it doesn't suggest hello, I need it to suggest words even after you press space.

I need help with javascript regular expressions.I have a text box in which user can enter only 4 types of values.
1) Varchar(n) where 0 < n <=80. Ex: Varchar(20)
2) Char(n) where 0 < n <=80. Ex: Char(20)
3) numeric(x,y) where x>y and 1<= x <=35 and 0<= y <=15. Ex: numeric(20,6)
If the text box value doesnot match this pattern, we should throw him alert message.
I am trying to add radio buttons in this quiz script that i'm using, but when i change the drop down box to radio buttons the quiz script stops working, i.e it will not calculate the correct answers / percentage.
I dont think i am correctly adding the input type "radio" and the script cannot recognise the value properly as i'am trying to make custom radio buttons from javascript / css.
Here is the script thats stopped working but how do i make the radio buttons send the correct value to the quiz script?

I'm trying to change what the user types in a text field if they hit a certain key combination. For example, "cx".
This code checks for the letter "x" to be pressed, then checks to see if the second to last letter is the letter "c". If it is, then it deletes the letter "x" and replaces the "c" with the letter "ĉ".
Code:
// This code checks for a certain keypress combo. For example cx, Cx, gx, Gx, etc...
// The hard to type esperanto characters we aim to insert.
var esperanto_c = "ĉ";

I have a form that has a bunch of text inputs, and I would like to select all that don't already have a class "errorClass" assigned to them. My JQuery currently is:
$('input[type="text"]').addClass("idleField");
But that adds the class "idleField" to ALL text fields, overriding the ones that already had the class "errorClass" assigned to it. What is the proper syntax to add the "idleField" class to all text inputs that don't have the "errorClass" assigned?
I'm adding a sub menu to my portfolio page that will allow a user to filter the types of projects they want to see, but I'm not really sure how to approach this. I have a variety of web design and motion graphics projects all on the same page, and I want the user to be able to "uncheck" one category or the other, and when they do, all the divs for the unchecked category will fade out. This is the page: [URL] Does that make sense? What I'm thinking of doing is applying a unique ID to the different categories, then build a little JS that will change the opacity of those specific IDs somehow. I am not a JS ninja though, and I'm thinking there is probably a more efficient way.

Parts of it would be VERY convenient if it could be automatically filled when page is loaded. Autofilling text boxes is easy enough.

I'm making a quick and dirty Google Calendar displayer with help from Full Calendar and am struggling to display the details of each Google event correctly. As you may know, if you're not logged into Google Calendar, if you're given an event link or invitation you will be taken to a dynamically generated page displaying the basic details of that event. It includes a <link> ed stylesheet and inline style="..." for each element. I have attached a screenshot of a typical event page.
I'm trying to strip out all the style and just display the content:
eventClick: function(event) {
if (event.url) {

How can I use jQuery to submit multiple forms with different types, values, and actions? For example:
Code:
<form name="form1" method="get" action="submit1.php">
<input name="value1" type="text" value="">

Can I start the jQuery process from within a function when clicking on the submit button?
So I have a function, and in that function there are two paramaters: index and newLocation. Each of these parameters can initially either be an integer or a string: The string can only be the values of "first" or "last". I can do a long set of code for both parameters, but I was wondering if there was a way to iterate through the parameters to make the code more compact and reusable.
if(parseInt(index, 10) == "NaN")
{
if(index == "first")
{
//The first index of the array
index = 0;
