JQuery :: Allow User To Add Data To Dynamically Created Lists
Apr 10, 2010
I want to create a recipe site with similar functionality to a feature on coolspotters. I've only dabbled in jQuery so I'm not sure how complicated it would be to do this. Basically what I want to do is allow a user to add recipes to dynamically created lists. For example if a user searches for Italian food they should be able to create a list called "Italian" and add italian recipes to the list. Or if they do a search for Japanese dishes they will be able to create a list called "Japanese" and add Japanese recipes to it, etc. I know their would be some back-end code involved but I was wondering if jQuery could handle the front-end. I've only dabbled in jQuery so this sounds like a complex thing to do.

I have some code that creates form fields as needed, then the once the user inputs data the values are stored in my action page as an unordered list. The list is then displayed back on my page with an ajax call. All this works fine, but now I wanted and need to have the lists sorted alphabetically. I actually found a thread here and some code someone posted to do this. I thought at first it worked, but it seems to be if'y. Maybe it has to do with the order in which I might add an item to my form. I also wanted to sort by more than the first letter. When I thought, and Im pretty sure it was, working, it seemed it only sorted up to the first letter. Ex:

I have an application that dynamically adds unordered lists forms as needed, then once the user(backroom) enters values in the form fields, the lists are saved to an action page and displayed. The lists are written to a page called vendorProductList.cfm and written as an unordered lists. Then that page pulls the html out and inserts the newly created list(s) into my page. Here is the code that does that written with cf:

I have some forms whose ID's are dynamically created via PHP by including a variable called "invno" as shown here:
<form name="formEditInvoice<?php echo $invno ?>" id="formEditInvoice<?php echo $invno ?>" method="post" action="javascript: SubmitEditedInvoice(<?php echo $invno ?>);" onsubmit="javascript: return ValidateForm(this);">
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) {
$.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(),
function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.

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

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 an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.

and what this function does it count the number of Characters that have been typed in a Textbox. so i am displaying the remaining characters. So that is working fine on my example because the Element is known at Early Binding. Now my question is what if the textbox is created dynamically ?
contentbox
this is the name of the Textbox in my example.

I have recently started exploring the world of jQuery and it looks incredibley rich and powerful! I am stuck on something, though. When I dynamically create a div
var divTag = document.createElement("div");
//Set the parameters
divTag.id = "divMaster";
//Create it and immediately hide it!
[Code].....
This is probably really obvious, but I cannot figure out why? Perhaps jQuery is looking for elements already in the original HTML, and my div tag was added to the DOM after loading the original elements?

The code below creates images based on a json feed, no problem. All images are created and the click function works perfectly, but... I can't access any of the images by their id's so I can't make thefunctionbehave as I wan't.
I first thought jQuery appended my image object as html and didn't insert it as a valid object in the dom, but as the click function is working that can't be it?
I found some other people had the same problem but they were using vanilla js, their solution was using .appendChild() but thatdoesn'twork in jQuery.
$.each(json.hotgames, function(i, item) {
var image = $('<img>')
.attr('id', item.uuid+':'+item.lane)
.attr('src', 'xxx')

I can see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.

Previously when developing my own modal windows I have been creating a "mask" div directly in my markup, in the CSS setting it to be display:none and then setting it to show() by jQuery when a button is clicked.
I'm sure there is a better way to do this but i'm getting a little stuck.
I tried adding the "mask" div and its content to the body using prepend() when my button is clicked but i found i then can't select any of the added elements in jQuery.
How can you select elements you have added to a page by jQuery?? Also if this is the right approach whats the best way to insert a block of html to a page??

I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
