Adding Onclick Handlers To Items Created From Array?
Feb 3, 2009
I am dynamically creating page elements by looping through an array and adding them to the DOM. Each element has an action that should be performed when it is clicked. This action (or a reference to it) determined by the current array value as well. Because the code called in the onclick handler is not executed until the event fires, the value of the current array item (at the time the onclick handler is attached) is not preserved resulting in the expected behavior not happening.Here is an extremely simplified example of the problem I'm facing:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I am running through a MySQL database using PHP and extracting all of the makes of cars in that database and trying to create a JavaScript array named after each make. Then I am trying to fill each array will all of the models for that make. When I just try to display each Make and Model in an alert box it seems to come up right. And my arrays seem to be getting created but they won't populate with the models (even though my alert msg shows the loops and everything is working).
PHP Code:
while ($row = mysql_fetch_array($result)) {
$i=0;
//Used so each model is added to the array starting at 0 and ++
$make = $row['make'];//PHP var used to extract data from MySQL
[Code]....
Haven't used JavaScript since a college class a couple of years ago and haven't used it in the real world for even longer. Never with PHP like this. But I am working on this marketing site and need to be able to list products by type according to each brand and as they can be added to a MySQL database it needs to be dynamic. I have the whole thing working by stepping through separate pages using PHP to populate select fields with the data but I want to be able to dynamically add the content to select field using JavaScript so it can all be done on one page and thought that if I could create these arrays on page load then the right information could be selected client side.

I have a simple filmstrip that uses getJSON to return data. The data is an array containing two arrays. The first, is the base path to photos. The second is a list of the photo file names. I am trying to loop through the array of photos and set them in divs. Then I need to attach an event to popup a larger view of the image placed in a dynamically generated div containing the image and initially hidden.
So what I am trying to accomplish is:
1. get JSON data from server.
2. get base image path from json data array
3. get list of images from json data array
4. Loop through list of images, prepend base path and assign to hard coded div.
5. create a dynamically generated div with larger version of same image.
6. Attach hover action to cause a mouse-over action on the hard coded div to popup the dynamically generated div containing the larger version of the image.
My issue is that once my code runs, no matter what image in the filmstrip I mouse over I always get a popup with the last image in it. Here is my code:
<script language="javascript">
$(document).ready(
function(){
$.getJSON("<?php echo site_url('filmstrip/index');?>",
function(data){
var dir = data['dir'];
var imgs = data['imgs'];
var i =0; .....

I wanted to add a onclick event handler to an image in a loop cos I have a dynamic number of images. The problem is I also need to pass a parameter. This works in Opera 8, but doesn't work in IE:
document.images[i].onclick = "javscript: ShowDesc(" + i + ");";
What am I missing?

<link rel="stylesheet" href="style1.css" type="text/css" title="style1"/>

Im trying to write a code to draw random numbers, like a lottery generator. It will require the user to input amount of numbers per line & choose the amount of numbers. From the numbers the user inputs it will generate random numbers to that guideline.
I have wrote the random number function, that works fine. Im having problems invoking it with ONCLICK event handlers. I cant seem to get the correct arguments. And all i get in return is "undefined"
This is the form for the onclick button
<INPUT TYPE = "button" NAME = "drawBalls" VALUE ="Draw the Balls!"
ONCLICK = "lotteryForm.drawnNumbersTextBox.value = ">
Now Im not putting up to much code, as its part of an Assignment, I dont want to cheat, i just want to be pointed in the right direction. :(

I am trying to add onclick event handler to many objects but I can't understand why it doesn't work. To assign event handler I use traditional approach as described in [URL]Heres the code (extract.js):
Code JavaScript:
//the class
function extract(){
[code]....
I know that both select tags don't have options, but I generate them with JS because they hold sequential numbers and this part has no impact on the problem at hand.Both functions help select next or previous index in a given select tag for greater comfort

was wondering when you create an input element, i.e.
var someInput = createElement('input');
How do you add an event to an input item?
like a onKeyUp event.

I'm building all my forms dinamically, calling a web service that returns me the field type, description and a set of rules for validation, all in JSON format. No matter how hard I tried, calling rules("add", ...) after adding the control to DOM does not work since I don't get the right format for the rules. Has anyone tried doing that (returning the rules with JSON and adding to a dynamic control)?
The rules come this way:
data.d[0].ItemRules
minlength:2
required:true

So i have a javascript function which clones a Node on my page. That part works fine, as does the renaming of all the controls. The part that i do not understand, and cannot get to work is that several of the controls have an onclick event. On the dynamically created controls this onclick does not fire. Does anyone know why this would be, or possibly how to get around it?

I'm trying to create a list, to which you can:
1. Add and remove items.
2. According to what's in this list, there should be dynamic content loaded on to the page.
I've accomplished 1 with the code below. I'm not sure about how to accomplish 2.
<script language="javascript">
var listItems = new Array();
var currentList = new String();
function listManager(task, id, name) {
//$("#debug").append(" ##### List manager. ("+listItems.length+"
items) #####
");
if(task == "add") {
refreshList(); // refresh the list .....

I would like to have two columns, the left column showing all available items with an add button. The right column showing all of the added items, and then adding these together to provide an order total, but with the ability for users to add to the quantity or remove from their order.I have the add item to order bit working on, and the sub-total is working.I started to try to add on add/remove buttons to the right #your-order column but am getting stuck.Every time a user adds another item to their order, more buttons are added, and I can't get the "remove item" button working.The page is located here:URL...Should I paste the jQuery code I am using here?

I have created an array that holds three textmessages, how can I
remove the created textNode and feed the next message in line? Is
there also an issue with cleaning any whitespace too?
A code snippet:
----------------------
var altTextBanners = new Array(
"myText1",
"myText2",
"myText3");
altTextBanners.currentIndex = -1;
function initRotate() {
if (!document.getElementById) return;
altTextBanners.currentIndex++;
var text = document.createTextNode(altTextBanners[altTextBanners.currentIndex]);
var message = document.getElementById("message");
message.appendChild(text);
// how to remove the created TextNode and get the next one in the array
// ... ??
}
HTML
<span id="message"></span>

I have a site that uses bullet points. I am able to add and delete these bullets as needed. The problem i face is every time I add a new bullet and update the page all the bullets that are already there are saved again. for example lets say I have in my list:
[Code]...
So I was thinking that I could get an array of all the existing bullets and then say if the new bullet is not part of the array update it. If anyone else has any other ideas of how i could make this work I am glad to hear them. If you need code just let me know.

I want to build a dynamic list of items with jquery but am unsure how to add an index number to each of the items i create so that i can reference them to edit or delete them for example. So far, I have the following which just creates the items and appends or prepends them to the element depending on whether one item exists already. I just need a way of adding an attribute so I can then reference the current item when clicked and remove it. What would be the simplest method to use?
//create list items
if ($('.mylistitem').length) {
$('.myList-box').prepend('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');
} else {
$('.myList-box').append('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]' + titleid + '"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');
}

I seem to be stuck on one part of my code. A quick background, this is a website to showcase various photography services. First, I will layout what I have:
The Javascript for my menu (in the head section):
<script type="text/javascript">
<!--
var timeout = 200;
var closetimer = 1;
var items = 0;
function dropit(id){
canclcls();
if(items) items.style.visibility = 'hidden';
items = document.getElementById(id);
items.style.visibility = 'visible';
}function mclose()
{
if(items) items.style.visibility = 'hidden';
} .....
Now, here is what I have in the body section
<div id="menu">
<ul id="control">
<li><a href="#" onmouseover="dropit('dropone')" onmouseout="mcls()">Wedding Portfolio</a>
<div id="dropone" onmouseover="canclcls()" onmouseout="mcls()">
<a href="jamaicawed.html">Wedding in Jamaica</a>
<a href="indianwed.html">Indian Wedding</a>
</div>
</li> .....
So the only thing I can't figure out how to do is create an onclick event for one of the menu items (boudoir) that confirms that the user is comfortable being exposed to a specific (topless) type of image.

I'm not entirely familiar with the norms and standard libraries of
JavaScript so if the answer to this is yesterday's news, please ignore.
I'm trying to write a simple text formatting function to make headings
proper case -- i.e. first letter of words capitalized.
I first tried this...
function inProperCase(s)
{
var result, i, k;
i = 0; result = s.toLowerCase();
while ((k = result.indexOf(' ', i)) -1) {
if (k - i 0) {
result[i] = result[i].toUpperCase();
}
i = k + 1;
}
if (result.length - i 1) {
result[i] = result[i].toUpperCase();
}
return result;
}
...but it didn't work. To my amazement, you cannot set a character in a
string by accessing that character with an index, like so:
s[i] = ch;
Must be because JavaScript strings are "Immutable" or "EtchedInStone" or
something. (Just kidding, no flames, please. I'm sure it is more
efficient.)
The only thing I could come up with was this (with some details, like the
"compound" while predicate, modified into a more readable form after being
called a "C-bigot" by a friend :)) which seems pretty heavy-handed with all
the string slicing and concatting:
function inProperCase(s)
{
var result = s.toLowerCase(),
i = 0, k = result.indexOf(' ', i);
while (k -1) {
if (k - i 0) {
result = result.substring(0, i) +
result[i].toUpperCase() +
result.substring(i+1, result.length);
}
i = k + 1;
k = result.indexOf(' ', i);
}
if (result.length - i 1) {
result = result.substring(0, i) +
result[i].toUpperCase() +
result.substring(i+1, result.length);
}
return result;
}
You call this as...
inProperCase(" madam i'm adam ");
...and you get...
" Madam I'm Adam "
Any suggestions for making this a bit more elegant?
BTW You may point me to a "library" with a super-efficient implementation
of this function, but that is not the point. My issue is, how do we update
single characters in a string (or single items in an array) in JavaScript?
Is it something like...
s.wouldYouCareToUpdateThisChar(i, ch); // :D (just kidding, calm
down...)
-or-
s.setCharAt(i, ch); ...

Right now, the array items print out without spaces like "Jane,John,Mary,Sue". I need to be able to work with the items individually so I can format them so they read "Jane, John, Mary and Sue". I thought I'd be able to do something like v[i] + ", " but I get an "undefined" when I try to alert for v[i]. Can someone point me in the right direction? Code:

I have a list of buttons in a javascript hangman game: (studying javascript with a hangman game someone else made)
Code:
<body bgcolor="f4a460">
<form name="board">
<font face=courier>
[code]....
What I'm wondering is if the '.elements[i]' part of the above function automatically refers to the array created by the form. I didn't know that forms could automatically be referred by the elements dom without having a name or an id assigned to it. Does a form, when created, automatically assign its values/buttons into an array that can be referred by DOM?
