Hidden Divs And Error Checking
Oct 11, 2005
I have a form that displays various hidden divs if a visitor checks a certain option in my form. For example, if they select Yes in a radio button a few more form fields will appear beneath it. It works fine except when the form is not filled out properly and the form is displayed again (using PHP). When the page reloads it doesn't show the hidden div unless they select No.
how to make it so if they select Yes, it will make the div appear again when the page reloads? Here's the code I'm using: Code:

I have been trying to do some tooltips for a website and desperately wanted to learn something new and do that with jQuery.However, every time a mouse hovers over a tooltip, all hidden divs are shown, not just the one that supposed to. Here's my html:
Code HTML4Strict:
<div class="tip">
<a href="#"></a>[code].....

Sorry this will be an ignorant question I know, but I'm just trying to implement some quick JS in my form to check if the fields were filled in:
function check_form() {
if (survey.form_firstname.value == "") {
firstname_error = "-Please enter your first name
";
}
if (survey.form_lastname.value == "") {
lastname_error = "-Please enter your last name
";
}
if (survey.form_phone.value == "") {
phone_error = "-Please enter your phone number
";
}
if (survey.form_email.value == "") {
email_error = "-Please enter your email
";
}
if (!survey.form_agree.checked) {
agree_error = "-You must be over 18 and provide accurate information
";
}
errors = firstname_error + lastname_error + phone_error + email_error + agree_error;
if(!errors) {
return true;
} else {
alert("There were errors:
" + errors);
delete firstname_error;
delete lastname_error;
delete phone_error;
delete email_error;
delete agree_error;
delete errors;
return false;
}
}
It only seems to work if no values are filled in, if one of the fields is filled in the error checking fails. Again, I'm extremely new to JS, i've only ever copy/pasted and this is the first time i've tried writing a piece.

I'm trying to understand how JS constructors work. In particular, I'm trying to work out how I can call a parameterised constructor and check that the values of the parameters are valid within an object that has private properties. So for test purposes, I construct a data of birth object like this:
HTML Code:
<pre>
function Dob( day, month, year ) {

I posted here a couple days ago and got help from a really nice forum member to get my script working. Now I'm a little embolden by the good experience and am trying to be a little more ambitious. As usual, I ran into a little brick wall on my own and need a shoutout for more help.
Here is what I have so far - a main panel where different image/texts are held in 'panel' div containers within another div container, under which is a nav bar consists of thumbnail images/links. Upon onclick on one of the thumbnail images, the 'panel' div containers are set to display:block or none, effectively 'switching' the panels.
Here is what I am trying to build on top of that - ability to set one of the panel div as 'display:block' at start (right now nothing show until one of the thumbnails is first clicked), and a mechanism to cycle through the different panels via a timer (interruptable via the onclick to show/hide command).
Here is my code so far:

I'm currently learning many web programming languages and figured this would be a good way to learn more and do things better. I have been working on a contact form for my website. I had originally did the error checking in PHP, but I would like to change it to JaveScript since this is the preferred way. I have it all semi working,It seems like I have some unnecessary variables and such.. I would like to clean it all up as best as possible.

I made a contact form for my website originally in PHP. I wanted to change it to JavaScript because that is the preferred way. Originally I had the form in my HTML file using a separate PHP file for error checking. For JavaScript do I have to make a separate page and call to it like the last time? I have put it all on my HTML page and where it was calling for the php page, I also put the JavaScript code. When I go to my site, the error checking is not working at all. There must be something wrong, but I haven't been able to point it out and I am very new to JavaScript. Also, when I go to my page and right click for the source code, the JavaScript I have in there does not show up. Below is my HTML code.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Contact_Form</title>

I am trying to create a basic menu where if you put your mouse over a button you get a bit of descriptive text or an image appearing somewhere else on the page. I have tried to do this with hiding/revealing hidden divs - works fine with IE but no others.

<script language="javascript">
var descriptions = new Array();
descriptions[0] = "<p>See whats been added to the web site recently</p>";

I want to use JavaScript when a button is clicked to show and hide a
SPAN or DIV. This works in both IE and Netscape, but what I'd like to
happen is for there to be no white space where the hidden div is.
I start with two visible divs and in between them are two more hidden
ones...in Firefox this works fine--the two visible ones are right next
to each other, the button fires the script and the other div shows up
in the middle. Another button hides the div and the original two move
back together without space between them.
However on IE the two visible divs are separated by the amount of
whitespace that would be needed if the two hidden divs were actually
visible. They show and hide correctly, but the whitespace remains.
How can I fix this? Code:

I'm trying to add some js automation to a blogging application I've developed for a wysiwig site builder program. This program doesn't allow php or any kind of server scripting, so everything has to be done with js. The basic set up is that a user enters a blog post in the application and the code below appends a comments div (which are already on the page but hidden by css) to the post:
Code:
Instead of using this code for every post instance, I'd like to create a simple loop that will assign an incremental number to the post and comments id's when a new post appears in the page's html, and then append a comments div to the post. I tried a for routine that would add 1 to every post, but couldn't get it to work right.

I am trying to create a tell a friend script and add the ability for the users to send the email to more recipients than what is hard coded into the form. I have come up with this so far but is wont allow me to let the user 'show more email fields' a second time. I dont know how to write the javascript to allow this? When I tried duplicating the divs and adding a 'show more' link inside the first hidden div it just showed both sets when I clicked.
PHP Code:
<html><head><title>Example</title>
<script type="text/javascript">
function showDivs(){
var arr = document.getElementsByTagName('div')
for(var i=0; i<arr.length;i++){
arr[i].style.display = (arr[i].style.display == 'none')? 'block':'none';
}}
</script> .....

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.

I am new to ajax, meaning I know nothing what so ever of programing ajax. I want to do a simple login interface with email and password (with php), but i also want that when I press submit button it show a box with "please wait..." message (this box must slide, from the top of the page). Also this box will display errors messages such as, "invalid email or password" and so on.

Trying to learn the basics... Here is a script for three toggle buttons that each when clicked open their corresponding divs. Fine. Now how does one go about automatically closing an open div when clicking on a new 'toggler' that opens it's div? I see other posts about this very question, but I'm just not grasping the logic.
jQuery(document).ready(function($) {
$("#toggle1").click(function () {
$("#toggle1div").toggle("drop", {direction:"right"}, 500);
});
$("#toggle2").click(function () {

I am using javascript to switch between a series of divs, on clicking a navigation tab the divs display property is set to 'block' and all other divs have their display property set to 'none'. That works fine, the problem I have is when I redirect to another page (e.g. a PHP script) on return to the index the divs have reset and only the default div is shown, rather than the div that was showing when the user left the page. The solution, as I see it, is two stages: Write a function to display the relevant div based on the variable passed to it, then work out how to pass this variable around various pages (post/get). I am very inexperienced with javascript and it drives me mad that the script literally does nothing rather than throwing up an error (as in PHP) but this is what I have so far in terms of a function:

I'm looking for some javascript to work with wordpress (jQuery preferrably) that will show/hide multiple divs on one click.
I had one working but it was kinda janky because it was causing me to have two divs with the same ID on one page. No good.
Since I updated to wp2.8.3 prior to launch, it's not working. So I've decided to just try and do it right.
Here's a page: [URL]
So, what I want to happen: On page load, the first tab: "general" and it's corresponding div beneath should be showing. And the first image should be showing. The other content divs and images should be hidden. I've given the text content divs a dashed border to show their borders. When a visitor clicks "dine at home" the general div and image hide, the second content div shows, as does the second image (it's currently the identical image, but the client may change later.) Etc.
I'll be using this function on a few other pages as well.
how to adjust this javascript to work on two different IDs at once?
current code:
Code:
<script type="text/javascript" charset="utf-8">
$(function () {
var tabContainers = $('div.imgswap > div');
[Code]....

I am trying to get a simple set of Javascript tabs to work properly. I have just two tabs and I want to set up the script to have the second tab automatically hidden prior to reading the javascript code because right now it shows the contents of both tabs when the page is loading and then the second tab disappears after all the script has loaded.
I have the jquery script linked to on the page and here is the way my script looks to run the tabs:
Code:
I want to add something like style="visibility:hidden;" to the DIV that isn't shown on page load and have it added and removed as necessary when users click on the tabs. So basically I would like the generated code to look like this:

Specifically, assume I have a div tag of absolute dimensions. I need
to figure out, first, whether or not the text inside the div tag is
partially hidden by the overflow setting, and if so, what the hidden
text is.
Is this even possible? Obviously, the rendering engine in the browser
"knows" this information, but is it accessible through Javascript?

I am developing a web page . For this i am using Javascript embedded in html. In the application ,the user can input data via interfaces in the page which is chosen and read from a master xml file , the chosen data then needs to be stored and saved in a xml file.I have designed the web page in FrontPage.
Now the problem i face is while trying to save the output xml file i get error Permission Denied , error code 0 . This happens when i try to open the page in browser IE 6.0 SP2.I am using DOM parser methods for doing the xml manipulations/savings etc.urprisingly this works in another machine.Also can i use the all of the same javascript code if i want to run it in an IIS. Do i have to do some changes to make it server side javascript code.
