Radio Element.type Undefined
Aug 25, 2006
I am using the JS and HTML code below to check that required fields are
completed for attributes of a product. The first attribute is a select
menu and the second is a radio set. My JS goes through fine and detects
if the select menu isn't selected with a value, but I keep getting
'undefined' for the radio element type. I've almost pulled out half a
head of hair wondering why. Any experienced eyes see something I don't?

I am trying to setup a form with radio buttons. Each radio button has an OnClick event. When a radiobutton is clicked the current set of radio buttons will be replaced with a new set using document.createElement("input"). Each new radio button needs the same onclick event addedas in the initial set of radio buttons. I first tried:
element.setAttribute('onclick', MyFunction(value));
This, however, will somehow automatically trigger the onclick event! I searched on the internet and found this as the solution:
var new_onclick = function() { alert("this works!"); };
element.setAttribute('onclick', new_onclick);
This will give a "Object" is undefined error!

I have a function which looks like
function mainLeftElements(){
var containerDiv = document.getElementById('mainLeft');
var elems = containerDiv.childNodes;
alert(elems.length);
}
Which for a div declared like so:
<div id = 'mainLeft'></div>
Alerts me it has a length of 1, trying to work out what the element is (thinking it might be a blank text element or something, maybe the id attribute also??) by using
elems[0].tagName
and
elems[0].id
I get confused as they both return 'undefined', so what is it?

I'm trying to find a way to change the CSS class for all my many input type elements with an onclick. Is this possible? The scenario I'm trying to fit it into is below (and condensed).
Ideally I'm looking to change the style for background-color onclick, black and white in particular (hoping that the solution would mean adding more colours later).

I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:
var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')
I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..

So 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.

What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1);
var s=r.concat([0,"",null,undefined]);
alert (s.toSource()) //==="[, 0, "", null, (void 0)]"
typeof s[0] //==="undefined"
typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()...
Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ...
I guess the question is actually, "can you tell the difference between uninitialized and undefined"?

I've coded in Java before but I'm still having some trouble. I am trying to draw a ribbon type shape on an <canvas> element and for some reason, when I turned it into a function, it seemed not to work. Here is what I have for drawing the ribbon with a function:
function drawRibbon(height,width,Canvas){
var c=document.getElementById(Canvas);
var cxt=c.getContext("2d");
cxt.fillStyle="#bb0044";
cxt.beginPath();
cxt.moveTo(0,0);
cxt.lineTo(0,height-50);
cxt.lineTo((width-20)/2,height-100);
cxt.lineTo((width-20),height-50);
cxt.lineTo(width-20,0);
cxt.shadowOffsetX = 5;
cxt.shadowOffsetY = 10;
cxt.shadowBlur=10;
cxt.shadowColor = "black";
cxt.fill();
cxt.shadowOffsetX = 0;
cxt.shadowOffsetY = 0;
cxt.shadowBlur=0;
cxt.closePath();
cxt.beginPath();
cxt.strokeStyle = "#ffcc22";
for (i=5;i <= 135; i=i+15){
cxt.moveTo(5,i);
cxt.lineTo(5,i+5);
cxt.stroke();
}}
drawRibbon(200,120,navCanvas);
I feel like it has something either to do with the function definition, or the call. Before this script is executed, i create a canvas in the following way:
<canvas id="navCanvas" height="200" width="120">
Why it is not displaying.

When I add radio buttons dynamically in IE6 they appear disabled.
Bascially the "checked" status is never visible.
I can set the checked status using the non-standard defaultChecked attribute, or after the element has been appended. But the radios still don't work - the "check" never changes when you click on a different radio input. Also the labels don't work (the radio is only selected if I click on the radio input itself).
The onclick functions I have applied to each radio input work fine.
I've tried several ways of creating the radios - jQuery, vanilla Javascript, etc. but can't get them to work.

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.

As recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.
Is this a bug or an intended refactor to be more standards compliant?
FYI - this is the selector I now have to use: $('input:text,input:not([type])')

I have a set of radio buttons that are wrapped in divs and I want to highlight the wrapping div (by adding a class) of a radio button that is clicked while removing the highlight from any previously selected radio button (by removing the class).
I've got it working to the point where it only works on one set of radio buttons but I need to be able to do this on multiple sets. I did find this but was not able to figure out how I'd apply this to my requirement as it is working the other way around here:
jquery-tip-how-to-select-radiocheckbox-input-on-click
why its working only on the last set?
$(document).ready(function(){
function radioHighlight(radioName, className) {
radioNameSelector = "input[name='" + radioName + "']";
$(radioNameSelector).click(function() {

I'm trying to make a form element only appear if a radio button has been selected.I have two buttons (yes and no).If Yes is selected I'd like a text input field to appear.I have the following:
Code JavaScript:
<script>
$('input:radio[name:scheme]').click(function() {[code]....
my group of radio buttons are named "scheme". I have tried this from a few angles but can't crack it. Ideally I'd like to use input:radio[value:yes]. It's already a required value due to the JQuery validation plugin, and I simply need it to make the other field visible when yes is clicked on.
