Ajax :: Button Eating My Lunch - And Dynamically Added Button
May 22, 2010
The main page is called Aj.html. In the 'head' I have mostly some functions to support Ajax call to server PHP (to just 'echo' something so I could see Ajax work). In the 'body', there is a little javascript and a form 'button'. When I click the button, an 'onclick' event causes a function to do the last step or two of the Ajax stuff... and the server PHP element is called... and then my ajax message handler back in Aj.html gets control to just send an alert... and that was the initial experiment ... and it was just so I could see how Ajax works.
Well - then I noticed that the 'button' is only clickable ONE time... And I set about to try to learn whatever I needed to learn to make that button be one that could be used to fire off the Ajax stuff multiple times... But I couldn't get that to work. So, I tried some code to remove the onclick event (during the ajax messaging handling logic in Aj.html) - and then add another onclick event to that same button... but that didn't work. Then, I tried to delete my button altogether - and insert a new button with it's own 'onclick' (which also would fire the ajax stuff) - but that didn't work, either....
Anyway... Now, my biggest curiosity (for the moment, at least) is why I can't dynamically add a button that has the needed onclick stuff to also fire the Ajax stuff... So, I guess I'd like to solve that right now.
What's currently happening is this: when I'm in the part of the code that is defining the dynamic button - and just before that button is added to the form, I define the 'onclick' that is supposed to be a part of that new button... BUT - when that assignment is made, it is almost like javascript is thinking that the request is actually in insert another onclick for the in-progress 'click'... because the new onclick is immediately processed at that point (I don't even make it to the next statement...just boom... the new onclick function is executed).
Also - the new dynamically added button DOES get added okay... but when I click that newly added button, it doesn't fire the Ajax stuff it's supposed to fire (via the onclick for this added button) - instead, it just causes what appears to be like a page refresh ... because the regular button reappears at that point (and then the Ajax stuff will again work off of that 'regular' button).
I'm including the whole script here.

I am trying to produce a web form to allow wedding guests to RSVP. The form allows them to enter a name and select from a radio button whether they will be attending or not. If they select the "yes" radio button then a further pair of radio buttons are displayed for their meal preference.
They can then click a submit button or they can click another button to add another line for another guest which operates in exactly the same way. I've almost got this working, but it seems that the checkbox change handler is lost for the current guest when a new guest is added and the checkbox value is reset. I've got a feeling I'm doing something stupid but can't for the life of me figure out what.
Code (source file (renamed to .txt) also attached as I'm not sure the pasted code is too clear):

I have a form, with a submit button. Inside this form i have one input text field, in addition to an add more button to add more of that input field using JQuery .html(val);. Now the issue appears when I submit the form, all inline added input fields are not recognized, they are not set and there is no data for them in the POST.

how to dynamically add another set of rows to a table when a button is clicked. The code below shows what goes into one set. When the button is clicked, it needs to create another three rows with the same format as the code below, but the variable names need to show what row they're on so I can easily call the values that have been inputed in another function that saves the information. Sooo for example the first variable, bhrs1-1 needs to become bhrs4-1 in the next set (because there's already a bhrs2-1 and bhrs3-1 in this set, which would become bhrs5-1 and bhrs6-1 in the new set).

I'm trying to write a Javascript quiz. The idea being that each question has 4 possible answers. The answers being in the form of multiple choice radio button. Instead of having either a long list of radio buttons and questions or loads of pages with tons of duplicated code, I'd like to make the quiz as one page. Pulling the questions, and possible answers from an array. All this I can do, except for changing the text on the radio buttons. In the past I've used.. getElementById with regular text to good effect, but can't manage it with the radio button. Here is part of my test code..

So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...

I have created a page which pulls search results from various sites using PHP. It displays each result in a row in a table upon running.
I wanted to add a button saying "More information" at which point, a div would appear and load the associated link for that search result within an iframe within the newly appeared div. I've been able to get a div appear and disappear on button click but, I couldn't get it to dynamically load an iframe on click with the associated search results link.

I am working on an MLA citation PHP script for books, and I already finished that part. I have the page set up so that the user may add as many authors as needed. However, when I use the back button, I notice that if I have more than one author, the dynamic text fields are gone and all data after the dynamic text fields are not loaded back into the proper fields.I've spent the entire day searching for solutions, and I tried saving the code to a textarea, then using that code to insert it back into the page on loading. However, I couldn't get it to work.[code]

I am building an online survey using a survey creation tool which allows me to incorporate javascript for additional functionality. However, I am new to javascript so would appreciate any help that you could provide me with.
I have question types like agreement scales, where the respondent sees a list of statements and has to rate each one by clicking on a radio button. The source code of the matrix table looks like this:
[Code].....
This code works as intended; however, as you can see, it loops through all the radio buttons when one is clicked. Is there a way to accomplish this without looping through all the radios, and thus make the script run faster?
Also, I have read that the addEventListener function does not work for older versions of IE. Is there a simpler alternative?

I have it set up so that there are three frames (frames and the use of javascript are encourage for practice) "bar" on the left with navigational options, "main" in the center where the body of the drill is presented, and "feedback" along the bottom where the feedback will appear.
My issue is that I have everything working except the form! I'm not sure how to make it so that upon clicking the submit button the feedback is presented in the "feedback" frame. This was suggested to me but isn't working, maybe I have a mistake somewhere? Or is there another way I can do this?

What happens is that when I click on a button, a random string from the RandomString variable appears below the button. e.g I click on the button and it displays 'AAB' and then if I click on the button again it may display 'AAE' and etc.
The problem is that sometimes it displays 'undefined'. I don't wanit 'undefined' to appear but why does it sometimes display 'undefined' rather than a Random string.
Below is the code:

I have a message system that I want to prevent double posting. So when a user sends a message i would like to disable the button. But its done using AJAX and will load without much time. But enough to cause double clicking. So now the button needs to be enabled once Text is put in the Form Field.

my AJAX is working in FF and Opera just fine, As in it repeats the function whenever the button is clicked, but in IE the first click works, but then it doesn't repeat...I've been searching around form some fixes, and found quite a lot but none of it seems to work [as you can see i've tried adding '.live' but still nothing]
Heres' the code:
<script type="text/javascript">
$(document).ready(function(){
[code]....
This is currently at the top of my index.php, but the button to run this function is echoed by php which I feel may have something to do with it?

I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.
Oh and that textbox is part of an array of textboxes, all of whose values i need.

I have a form where the users can add "name" and "id" fields by clicking on the "Add" button.
The input fields look like this (each pair is a row):
The 'name' and 'id' attributes are dynamically named with the integer increasing in value, by 1, for every new field.
As this is client controlled, I do not know how many rows there will be...
