Make A Degree Object That Inherits From The Number Object And Uses The Number Constructor
May 20, 2009I'd like to make a Degree object that inherits from the Number object and uses the Number constructor but adds a .rad() method that returns the value in radians.
If I do something like:
It generally works but I don't get Number's methods like toString and toPrecision.
Change Value Of A Number Object
Aug 26, 2005I'm hacking on a LISP interpreter in JS [1], and running into trouble with numbers and Number objects.
This is what I have:
var a = new Number(1);
var b = a;
document.writeln(a == b); // true
b = 2;
document.writeln(a == b); // false
document.writeln(a); // 1
Instead of replacing the *Number object* b with the *number* 2, I'd like to assign 2 to the value of the Number object, which should still be referenced by b *and* a. In other words, the two last lines should output "true" and "2".
Simplifying A Large Number Of Similar Object Definitions?
Mar 24, 2009I am looking for a way to simplify a large series of �object definitions� in the form:
var Img0 ={init:function(){Img0.div = document.getElementById("img0"); Img1.init();}};
var Img1 ={init:function(){Img1.div = document.getElementById("img1"); Img2.init();}};
[Code]....
The program I have developed (for animated greeting cards) works fine but for a large number of images there are an equal number of these object definitions. I am aware of such techniques as using �+i+� in place of the numbers 0, 1, 2, ... and assigning an increasing value to i in a loop. However, I do not see a way to use such a loop here.
Generate Unique ID
Jul 23, 2005I have a page with 641 images in it. Each image can be clicked with as
result that the image source will be changed. For this the images need
to have a unique ID. But to do this manually for 641 is just too much.
Is there a way to give each image his own unique id without setting
them myself?
The image:
<img src="images/hokje.gif" id=""
alt="">

JQuery :: DatePicker - How To Use Non Unique ID
Oct 12, 2011I have been trying to figure this out for a while, and I cant manage to get it working. I have a table for instance the one below:
<tr>
<td><input type='text' id='test_value[]' .... /></td>
<td><input type='text' id='test_value2[]' .... /></td>
<td><input type='text' id='date[]' onclick ="testfunc(this);" .... /></td>
</tr>
Within my function I can grab the index of the onclick no problem, but when I select the date from the date picker, it always select the first column.
testfunc(val)
val.parentNode.parentNode.rowIndex
I am using clone to create multiple instances of a row, but how can I use non-unique id (date[]) which all my X rows have the same name, to unique enter the datepicker value.
JQuery :: Loop Through <ul><li> Using Unique ID?
Apr 28, 2009I am trying to loop through my top level nav i.e <ul> <li> and then apply that class name to teh sub level menu of that particular top level. So essentially the clas name on the top <li> wil be applied to its sub level items. Here is my code, which isn't working at the moment:

Toggle Checkboxes On/off With Unique Id?
Mar 24, 2010I'm using the following code to toggle checkbox checked and disabled attributes.
var f = false;
function tick(group) {
if (!f) {
for (var i=0, len = group.length; i < len; i++) {
[code]......
The checkbox doing the js call uses onclick="tick(country)" and the checkboxes that I want to toggle all have the same id e.g.
<label><input type='checkbox' name='uk[]' id='country' value='England' />England</label><br />
<label><input type='checkbox' name='uk[]' id='country' value='Scotland' />Scotland</label><br />
This all works correctly but does not validate.I need to use unique id's for each name.The easiest way (as each checkbox html is generated by php) is to append the value to the id i.e.
<label><input type='checkbox' name='uk[]' id='countryEngland' value='England' />England</label><br />
<label><input type='checkbox' name='uk[]' id='countryScotland' value='Scotland' />Scotland</label><br />
How can I modify the javascript function factor this in i.e. toggle where id contains country?

Unique Random Numbers II
Aug 22, 2002This script is a slightly modified version of "Unique Random Numbers". In this script it becomes easier to implement more than one instances of "Picking Unique Random Numbers".
This JavaScript picks up a number of unique random elements from an array.
For example; if you have an array myArray consisting of 10 elements and want to pick 5 unique random elements. Suppose initially myArray[3] is picked randomly, then myArray[3] should not be picked again.

Generating A Conscutive Unique ID
Oct 14, 2006I need a script that will generate a unique ID consecutive to the previous one when a user submits a form. For example, I submit the form and the confirmation page shows:
JGH100354101
I will need the next user that submits the form to have the confirmation page show:
JGH100354102
and so on and so on...
Is anyone aware of a simple form script that would accomplish this?

Getting Three Unique Random Numbers?
Apr 13, 2009My Name is Tom I am from the UK and I am (for my own entertainment and learning) creating a dvd indexing web application to sort and catagorize my dad's dvd collection. On the homepage for this website I have dynamically (using JS) appended 3 image elements which contain the images of dvd box art at "x by 225" pixel dimensions i.e. when I resize the dvd box art they all have to be 225 pixels in height and constrain to the necessary width in contrast to the height. Now that the images are working, I now want them to be randomized so 3 unique box art images are displayed everytime the page is refreshed. So far my script is:
Code:
// Image Rotation Javascript
function imageRotation()
{
// Preload images
[Code].....
Problem with this is that sometimes I get results from the random number generation that are non-unique i.e. sometimes random_number1, random_number2 and random_number3 yield: 3,3 and 11 etc. I need to make it so that you never get such clashes or it will show 2 or more identical images on the homepage. How can I change the random number generators to achieve this?
how to plug the imgObj into the image elements as to use the preloaded images instead (at the moment their just hard coded.)

JQuery :: Select Two Unique Elements By ID
Jan 30, 2010Let's say you have two elements, and you know their IDs; is there a way to select them both at the same time; something like $('#test #test2')?I realize I could just select them both on two different lines and apply the same function, or use class or something to track them down; but sometimes I just want to grab two elements by ID and do the same thing to them. I assume I'm just missing the syntax.

View 2 Replies View RelatedToggle Expand / Collapse - Unique DIV ID
Aug 11, 2007I realize that expanding/collapsing DIV scripts are common but I can't find one suitable for my code. Most of them seem to rely on a unique DIV ID. I have the following XHTML code on my page.
Code:
<div id="container">
<h1>List of Events Happening:</h1>
<div class="event">
<div class="eventtitle">
<h1>Event 1</h1>
<p><a href="#">[ expand++ ]</a></p>
</div>
<div class="eventbody">
<!-- stuff -->
</div>
</div>
<div class="event">
<div class="eventtitle">
<h1>Event 2</h1>
<p><a href="#">[ expand++ ]</a></p>
</div>
<div class="eventbody">
<!-- stuff -->
</div>
</div>
<div class="event">
<div class="eventtitle">
<h1>Event 3</h1>
<p><a href="#">[ expand++ ]</a></p>
</div>
<div class="eventbody">
<!-- stuff -->
</div>
</div>
<!-- etc. -->
Basically I want my link to expand the .eventbody for the particular .event and there could be an unlimited number of .events. I'm not sure how to go about achieving this. I've already got a script that toggles the display(block or none) for a DIV, but it relies on a specific DIV ID.
Generate And Add An Unique Identifier To The Email
May 5, 2011I am developing a html ordering system that does not use a database but sends the data via email. To differentiate between two orders I would like to generate and add an unique identifier to the email. One approach I have seen is using data object to generate an unique id:
function uniqid()
{
var newDate = new Date;
return newDate.getTime();
}
This is not guaranteed to be unique as two people can send their request at the exact same time. One question pops up, the data being generated, is this local or utc time? Also, the number being generated in this situation is quite big and not so easy to differentiate two orders for a human. Ideally I would like to generate a global sequence starting at 1 and incrementing by one for each user that clicks on the order button regardless of timing, timezone etc. Is this possible given the constraints given at the start of the post?
Loop Through All Unique Names On A Form?
Sep 13, 2011I've got about 40 check-boxes on my 1 form. These check-boxes all have names (obviously) but they are NOT all unique names. The number of UNIQUE names on my form is probably around 8 or 9 (the actual number is NOT important). Because some check-boxes use the same names as other. It's set up this way, please don't ask me to change it, I can't change it.What's the syntax/method for looping through all the names? I was thinking I should do maybe a "for" loop;
for (var i = 0; i < fieldName.length; i++)
But I don't know how to hold a variable of the unique names to start with.
