Array To Populate HTML List With Sublist
Aug 14, 2011
I want to use arrays to populate an HTML list. I can populate the main list items but I can't seem to get the sub list items to work.
<HTML>
<Body>
<ul>
<script>
var pages = ["page1", "page2","page3"];
var subPages = ["sub1","sub2"];
for(var i = 0; i < pages.length; i++){
var page = pages[i];
document.write('<li>' + page + '</li>');
if (page == "page2"){
document.write('<ul>');
for(var i = 0; i < subPages.length; i++){
var subPage = subPages[i];
document.write('<li>' + subPage + '</li>');
} document.write('</ul'>);
}}
</script>
</ul>
</body>
</HTML>

How can I add class to a list and the sub-list...? I have tried the code below but it wont work...
Code:
$(document).ready(function(){
$("#menu li:last").addClass('last');
$("#menu li li:last").addClass('sublast');
});
This is the html code which I add the class 'last' and 'sublast' manually... the ideal situation I wish to achieve is to add these classes through jquery. Is it possible??
HTML Code:
<div id="menu">
<ul>
<li><a href="#">NEWS</a>
<ul>
<li><a href="#">News</a></li>
<li><a href="#">Opportunities</a></li>
<li class="sublast"><a href="#">Newsletters</a></li> .....

The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.
Code:
//creates the Project dropdown list
while ($proj = mysql_fetch_array($project)){
$id_proj = $proj['projid'];
$name_proj = htmlspecialchars($proj['projectName']);
[Code]....
I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.

I have 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.

I have several lists each of several hundred selectable items. I send
all lists to the client along with the javascript. When the user types
the first letter of the item in a text box, I know which list to
present- it is likely the user will wish to view several of the lists
concurrently (I am not concerned at the extra load time of a few
thousand items sent via javascript). However, I am trying to do
everything client side- (even if I use ajax to call the list from the
server, there is delay at the client side as the listbox is populated
with appropriate items) - can anyone think of a manner of presenting a
long list dynamically, based on the first letter typed, client side
and with the absolute minimum of delay? (These items then need to be
selectable)

I know that this is very basic to most of you JS Guru's out there, but I am stumped. I have found dozens of tuts on this, but can't seem to find a VERY simple basic version of it. This is what I want, actually my client wants. I want to have a select list that gives the options of countries. Then upon selection this changes the drop down list of the states/provinces listed. So when I click on Europe it shows the different sections of Europe, and US it shows the states (I'm sorry I don't know what Europe calls their equivalent of a state), etc.

I am facing the above problem for a chatroom app that I am making. People will enter and exit the room any time they want, so i need a member list that updates itself to reflect this on the screen of all users that are in the chatroom. What i have thought of, is to have JS call a PHP function on specific intervals, and that PHP function will retrieve user data from a database and pass it to JS to display on the list. Is this method advisable? Are there any more suitable ways of doing this? I am thinking of applying the same theory for displaying and retrieving chat messages, but i get the feeling that something's missing for this, or maybe this method is not right for displaying messages.

I am using Javascript & PHP to populate a select list. The Ajax is working perfectly as I have tested it. However, as you can see from the below code, I have a button which adds more rows (which includes 2 select lists and file input) to a table.
When I click Add Row, the row is added perfectly and both select boxes along with the file field are shown as expected. The problem occurs when I select a value from the "room_name[]" box - there are no values returned inside the "album_title[]" select box. It doesn't seem to be triggering the onChange event.
code JavaScript:
function addRow(tableID) {
var table = document.getElementById(tableID);
[code]...

how to create a somewhat simple form. The form will have text fields for 'Name', 'Phone', etc. What I want is to have a drop down list, which has different insurances to choose from (i.e. Medical Insurance, Dental Insurance, Senior products), and say when I choose 'Senior Products', new text fields pop up within the form to add their 'Address' and click a checkbox that states they authorize to be contacted. These new fields aren't visible unless they choose 'Senior Products' from the drop down list.

Have a WAMP setup with Apache, PHP and Mysql service and I�m working on a HTML form which will have two drop-down controls where information is extracted from two tables in my DB.The first drop-down list called (name="sel_ControlArea") will decide what information the second drop-down list will have.So far I have managed to populate them when the page is loaded using PHP but run into problem when I make a change on the first drop-down list.Question one: What is the best/correct way to solve this problem?Is it to load all information into PHP arrays and then translate these to Javascript arrays, or should I go for AJAX, or XML or are there any other better ways ?I have tried to solve this using the first method, put data in a PHP array but run into problem with this data not properly loaded.This is first time for me to pose a question so please let me know if I have left out some important information or if I should describe this problem in a different way.

I have a div what will contain a various number on images and I need to put all their src's into an array. Is this doable? Heres the code:
<div id="imageHolder">
<!-- ONLY CHANGE THE SRC, NOTHING ELSE -->
<div style="width:770px;height:400px;overflow-y:auto;margin-bottom:5px;">
<img src="[URL]" alt="" width="750" id="mainImage"/>
<br /><br /></div>
<img src="[URL]" alt="" width="240" height="120" onmouseover="Images = this.src;alert(Images)" />
<img src="[URL]" alt="" width="240" height="120" onmouseover="Images = this.src;alert(Images)"/>
<img src="[URL]" alt="" width="240" height="120" onmouseover="Images = this.src;alert(Images)"/>
</div>
Ignore the onmouseover code I was attempting to do this but so far no luck.

I am not sure this is possible but it seems like it should be. I want to populate a javascript array with all the image files in a dorectory. I want this to be dynamic so that when I add an image to the directory it get included in the array.
Any ideas? I am sure there are many javascript wizards out there who can point me in the right direction.

I'm having some issues with my code. I'm trying to pull data from one array and use it to populate a new array. With my initial array I can get the results of certain properties using 'servos[i].application'. Any servos that share their value with that of my filter box should be put into a new array called matches and allow me to referance them in a similar way 'matches[i].application'. At the minute I've got my code to populate the new matches array, i'm pretty sure, but when I try to get data out of the second array using the 'matches[i].application' style of query it says its undefined. I already have an array called servos which is full of 49 different servo objects. I've added the function containing this code and commented it too.
PHP Code:
function dataPull(){
//create servoStore to build page for display
//var servoStore="";
// search and get servos meeting application filter settings
// create new array called matches with set properties
var matches = new Array("application", "sclass", "type", "motor", "bearings", "gears", "modelno", "name", "speed", "v3_3", "v4_8", "v6_0", "v7_2", "weight", "dimensions", "opvoltage", "image", "description"); .....

I'm implementing the Sortable future from MooTools, currently, I'm tweaking it so I'll be able to use nested lists, just in the way I want it.
[Code]...
In this Sortables object, I need to retreive some elements from this CURRENT sublist. As you can see, for the moment I've placed a % sign, where normally an integer or another key would fit. In PHP, we know the function "current()" for this. But how do I fix this in JavaScript?

I have set up my website quite some time ago that has served its purpose very well, however I will now be adding an order form functionality. So far, by reading books and traversing forums, I have been able to develop a page where the user
1.Enters data into the required fields, that is then submitted to a MYSQL database via PHP,
2.Can retrieve orders that are stored in the database,
3.Delete orders that are stored in the database.
I have wamp installed on my computer as the webserver. I have also incorporated two drop down lists that both retrieve their values from tables within the database. The first drop down list retrieves the Australian States that I have stored in a table, and once the submit button is pressed, it stores the State that is selected to a separate table. This drop down list functions as it should. An extract from "From Place an order.php"
<?php
$dbcnx = @mysql_connect('localhost', 'root', 'tingling');
if (!$dbcnx) {
exit('<p>Unable to connect to the ' .
'database server at this time.</p>');
} .....
The second drop down list retrieves product names from a table that contains products and their prices. What I would like to happen, is that when the product is selected from this drop down list, a text box is automatically filled with its corresponding price. I had this drop down list working as per the "States" drop down list, but could not get it to auto populate the text field. I got some assistance from a friend and was able to get the text box to auto populate with its corresponding price, however when the page was submitted to the database, the "id" number of the product name from the drop down list was stored, and not the product name.
<select name="productSelection" onchange = "getProductDetails(this)">
<option selected value="1product">Select Product</option>
<?php
$products1 = @mysql_query('SELECT * FROM products');
if (!$products1) {
exit('<p>Unable to obtain author list from the database.</p>'); .....

I have broken this problem down to its most basic element, though my real task is a bit more difficult. My situation is that I have a html page with javascript, and a javascript function that I want to populate an html div tag with (see the example below). What is happening is that the div tag is getting populated and displayed ever so quickly, then erased and replaced with the original html ouput. So, in my example below, I get the first div tag (div1) to display as the page loads (a form with a simple button). When the button is pushed, I populate the 2nd div tag (div2) with a simple text statement. It displays quickly then gets erased and the original display (from div1) is redisplayed by itself. I have zero clue why this is happening and I have tried many variations.

I am developing a web application in java (jsp's and servlets). For the project I am working on I will need to develop an html data entry screen and the code to load data into the screen, and then save the data back to the back-end database.
How to do the following:
Read the data out of the database (JDBC, no problem) in a servlet.
Put the data into the appropriate form for returning to the data entry screen, which will be a jsp. (Is JSON the right choice for passing the data from the servlet to the jsp?)
In the jsp, parse the returned data and populate the HTML form elements (text fields and combo boxes). When a button is clicked, pull the data out of the form elements and return to a servlet for saving back in the database.
