Buttons Recognizing End And Beginning Of Array?
Jun 21, 2010
I'm new to programming so please please bear with me. I found this code, and I saved it as a .js -Everything is working fine but what I would like is for the 'next' button, to recognize when the array has reached the last image, so that 'next' button becomes unclickable and it only allows the user to click on 'previous'. (and same goes for the previous button, when it reaches the first image, then the only option is to click on next)
Here is the code:
(For javascript. Saved as a separate .js file)
var num=0;
[code]....

I've got a table in which I want to have certain elements changeable if the user presses a button. The elements are stored in an array and I want to cycle through them when the button is pressed.
Here's a section of what I'm working with so far:
I've tried using the ++ and -- to change the value of s, but it's not changing the text.

I am starting to learn javascript and have been trying to make a image gallery. I was hoping to take an array of src and create a link for each one which when clicked on changes the src of an already existing img.My question though is how would I make the buttons for the numbers.I feel like a loop would work for this but I just can't seem to figure it out. I don't know how far off I am in thinking that through a loop I could create functions with a name plus the i variable.And in each function there could be something like:
Code:
document.images["destination"].src = images[i]
That would then produce an <a> with the href equal to the function name + "i" with the title being "i" as well.
Am I way off? How would I execute that? A little explanation about my code. I am going to be using a loop to add the images that will vary in amount for each page that is why I have the push function just for this test. And the document.ready is because I've been using some jQuery.
Code:
<script type="text/javascript">
$(document).ready(function(){[code]...............

Within my project, using PHP/HTML/Javascript, I am trying to set up a page where a corresponding submit button is enabled when a given checkbox is checked. What complicates my attempt is that the checkboxes and submit buttons are in the form of arrays. Here is a snippet of my code:
<form name="myform4" id="list_apps" method="post">
<?php
for ($i=0; $i<$num_rows;$i++)

I'm trying to write a cinema seat selection page and I'm hitting a problem with a selector not recognising a 'booked' class that I've just been added via JSON. I wonder if anyone could tell me why it works ok when I hard code the 'booked' class in but not when I do it through jQuery. Should I just do it in PHP??? or is there a way around the problem.

I basically want to have a select element's options change when I add a class to an img element through a jquery UI droppable. For some reason even though I can see the class has been added, the alert will not display when it does change. I can't understand why.

$("#trash").droppable(

I'm encountering errors with a form I have created. I feel confident that the issue is with my JS validation form because when I allow the form to submit without validating any of the fields, my php processor correctly uploads all the content into my database (but, I will need the form validation to prevent the user from skipping fields).
The issue (I believe) is with IE. In IE, both drop-downs seem to populate correctly but when I submit the form, I get a prompt to make a selection for the first drop-down menu.
The form does submit properly in FireFox and Safari but with some testing I noticed that I was getting a prompt to make a selection in the first drop-down in instances where a selection was already made but I just had not yet populated the second country/state drop-down.
Still, in Firefox and Safari, the form does pass validation upon submit.. So, I am hoping it's just IE specific issue.
I'm thinking the issue is with IE not recognizing my selection. The form had a drop-down menu where the user selects a letter, then that selection triggers (in JS using a function to process the selection) another drop-down to populate with all the countries or states that begin with the letter from the first selection.
Here is the code from my form:
<p><span class="title">Sign Up</span></p>
<br />
<form id = "signupForm" action="signup_process.php" method = "post" onsubmit="return validateSignupForm();">
[Code].....
what could be going on in IE that is not allowing the form to pass JS validation..

I have an Ajax script which works fine in IE, Opera, etc, but not in FF 3.6. It appears the data sent is not recognized. My debug alert to display a simple variable sent is blank. In other browsers it displays fine. I'm developing on my PC so shouldn't have the cross domain issue, I don't think?
Here is the code
function ajaxRequest() {
$.ajax({
type: "POST",
url: 'WTE_HTTP_Submit.cfm',

I am implementing Ajax for a new website and I've run into a hurdle.
It seems like Javascript does not 'see' any div elements that are loaded from external file with Ajax.
Is this a common issue, and is there a solution? Or am I overlooking something obvious?
What I'm doing is loading a simple external page via Ajax. The pages loads just fine, and it contains div's with unique id's. If I execute a Javascript function, it seems to not recognize these newly-rendered div's from the Ajax external file. Is this the case? Can Javascript be re-invoked on command, so it can see the new div's?

I have a multiple choice quiz that works fairly well. However, instead of it presenting "End of Quiz" message when last question is completed I need it to take the user back to the beginning (question 1) but with no indication to the user that this has been done. How can I adjust the code to have it do this?
<script language="JavaScript1.1">
var whichone=1
var tempmn=document.quiz.thequestion

I'm in need to be able to create a matching picture game, in which I have rougly 9 images to be able to match, but 18 in total. I have started with a thought of having a button that; when pressed it will disappear and show the image that is within the function.
Progress; I am able to press the button and let the image load, but in this case everything goes fine (image resized, not sure about the id though) but the image doesn't show, it just shows an [X]
yet when I just put
<script language="Javascript" type="text/javascript">
function callImage(){
document.write("<img src="images/truck0.jpg">")
}
</script>
The function works fine when I press the button.
