Display:block And Sending Form Elements
Feb 8, 2006
I have a feature similar to 'folding', where the user can hide parts of the page if they dont want to use these features.. some of this is done automatically, if a user chooses one type of template on the page, the settings for that one are displayed (and the other settings invisibleised).
Originally I did this with php, reloading the page with a variable to switch the sections on or off. This was proving to be a pain re speed and also cos there were a lot of form elements that needed to be saved each time it was reloaded.
So I decided to do this with javascript, using the following function:
function toggleDisplay(divId) {
var div = document.getElementById(divId);
div.style.display = (div.style.display=="block" ? "none" : "block");}
using block and none to either display or hide.
Problem is, I have lots of form stuff in the areas that will be hidden, and these are getting sent through on submit even though they are in a div thats set to display:none. I was hoping display:none would actually result in these not being sent.
anybody know of a nice clean way of preventing these hidden elements not being sent? (there are lots of em so it would have to be applied to the whole div that contains em)

So never done this one before so I am having a bit of a time trying to figure this one out.
Say I have a list of LI element and only a few of them have a inline style of display block, the rest have a display of none.
How would I go about looping through and dertmining the number of elements that have a display of block?
for(var m = 0; m < li.style.display.length; i++)
{
alert(m);
};
The above is just crazy but where my mind melts..

javascript Code:
$(document).ready(function() {
$('#signup').click(function() {
$.blockUI({ message: $('#blockform') });

I've got a <div> inside a <form> which I show/hide when a user clicks on a show/hide link. That div holds several form options which I DON'T want to submit with the form when the div is hidden.
At the moment, even when my div is hidden, the values within it are still being submitted with the form.
Is it possible to / how do I - hide the div so any values enclosed in it do NOT get submitted along with the form?

I am creating a form to enable advertisers to create listings on an accommodation directory site.One of the form fields is a drop down with the following optionshotelguestHouseselfCateringinnholidayParkcampingThe top part of my form is the same for all these accommodation types. However I need to include a section specific to the accommodation type. This section will include groups of radio buttons and checkboxes allowing the advertiser to choose which facilities/amenities are available.For exampleA hotel may have 24 room service campsite may have a shop on siteI was planning to have a separate div for each of the accommodation specific sections and toggling the display based on the choice of the accommodation type from a drop down list.I have just had a horrible thought that it may be possible if javascript was not enabled that either none of the sections would be displayed or even worse all of them at once.

I have a javascript/html/css issue that I'm trying to solve for about 3 days now, with no luck. I'm using javascript to toggle the visibility of a certain table. I set the table's display property to none (via js) in order to hide it and to block in order to show it. However, applying block in the display property of a table seems to be having trouble with firefox.
See below what display:block does to a table in firefox: This simple html code:
<table style="display:block" border="1" width="100%">
<tr><td width="100%">test</td></tr></table>
produces this result in firefox:
Notice how the td has the size of the content and does not stretch to the size of the table (although it has a width="100%")? In IE it works fine btw.
If I change my js code to apply "table" to the display property of the table in order to show it, it doesn't show up at all in IE!

First of all, I'm an absolute newb in jQuery. My problem: I have let's say 3 square div's. Beneath these div's are 3 hidden div's, but they are on the same place in the layout. If one of the top div's gets hovered the corresponding bottom div should display, while the rest should hide. And if you move your mouse out of one of those 3 top divs, while not hovering over another, the correspondingbottom div should not change but just stay visible. I searched a while on the internet, but have not yet found anything that fits my needs or for which I have the skills to adjust it.

I've got an annoying non-working bit of code:
<div id ="messageDiv" style="display:block;">No profile information entered yet</div>
<script type="text/javascript">
function profileInfo() {
var m1 = document.getElementById("marital1").innerHTML.toLowerCase();
var b1 = document.getElementById("bodytype1").innerHTML.toLowerCase();
[Code]...
The first part up to before the 'else if' works. but if the 'w1' has [URL] it still doesnt return true and display the DIV block??

Having a few problems with a form validation script. Its supposed to stop sending the form if key fields are missing, but it just sends them anyway!
Below is the code i use in the header to check for blank fields:
Code:
And now the code i use to action it:

From what i can see the fields match, it all links up correctly but still it will allow blank forms to be sent.

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 have a form that calls a perl script. A few javascript routines in
the form do a few things prior to submitting. For some reason,
however, the perl script is being called twice (the perl script sends
out an email, and submitting the form once results in two identical
emails.)
Here are excerpts from the script that I believe to be relevant (I can
post more if this isn't enough, but it's long and I'm trying to keep
it brief.) Can anyone tell me what I'm doing wrong? I've read about
how you need to return true after calling the javascript via a button
click, but I've done this kind of thing in other places and it's
worked fine. I've also tried inserting a return statement here in the
function and it doesn't seem to make a difference. Strange. (BTW, I
changed the domain name in the URL out of courtesy to my client, just
FYI.) Code:

I want to get IE5 to send the contents of an HTML form by e-mail using Outlook. I know that the basic idea is to make the recipients' e-mail address the Action. I can make a blank message open addressed as required but I can't get the user's input to appear in the message body.

I'm having trouble validating a form with javascript before sending it to a php script. Even when the form fails validation it still sends to the php. I believe it's to do with my validation script. You can see the script live here: [URL]
HTML Form:
Code HTML4Strict:
<form action="includes/verify_login.php" onsubmit="return validate_login(this);" method="post" name="login_form">
<label for="user">Username</label><input type="text" class="custom_field" name="user" id="user">
<label for="pass">Password</label><input type="password" class="custom_field" name="pass" id="pass">
<input type="checkbox" id="remember" name="remember"><label id="label_remember" for="remember">Remember Me</label><br>
<button id="custom_button">Login</button>
</form>
Javascript:
Code JavaScript:
function validate_required(field){
with(field){
if (value==null||value==""){
document.getElementById("empty").style.display="block";
return false;
}else{
return true;
}}}
function validate_login(thisform){
with (thisform){
if (validate_required(user)==false){
name.focus();
return false;
}else if (validate_required(pass)==false){
comment.focus();
return false;
}else{
return true;
}}}

I have this function:
var CntEmails=0;
function CreateEmails(id,name){
//passo1: criar elementos
br1 = document.createElement('BR');
emailText=document.createTextNode('email:');
email = document.createElement('INPUT');
// passo 2: anexar elementos
gEBId(id).appendChild(emailText);
gEBId(id).appendChild(email);
gEBId(id).appendChild(br1);
// passo 3: definir tipo de campos
email.type='TEXT'
// passo 4: definir value
email.value=CntEmails;
// passo 5: definir name
email.name=name+CntEmails;
// passo 6: incremental contador
CntEmails++;
}
gEBId() -> means getElementByID();
Using the function:
HTML Code:
<input type="button" onclick="javascript:CreateEmails('emails','email');" value="+">
<div id="emails">
</div>
This function works fine (thanks to sitepoint users).
But I cant send the variables by a post method. If I try in php: print_r($_POST) or var_dump($POST) I just get the static fields.

We have a form on our website, which ends up being sent to an e-mail address. The only problem is that some people access this form using public computers. When they press submit , the Internet Mail Wizard pops up and tries to make them setup a new account. Obviously because they are using a public computer we can't have them setting up e-mail accounts on that computer.

I have a form on my website that takes registrations for my classes. The form currently is sent to a php that checks for empty fields. If all is good, they are passed to a thank you page. If any empty, they go to a page that reminds them to fill in all required fields, where I've provided a history-back button. Problem is that 1) the captcha image isn't refreshed, and 2) with 14 fields, they have to find the missed field!
This is where I thought that This Script would work great. It adds a "sentence image" in red when a required field is missed. This would keep the person on the same page, and highlight the missed fields!
My Problem; I've tried to adapt the script to my already existing form, but when I click the submit button, I quickly see my tables "expand" from the inserted image (haven't sized the image to fit yet, so it enlarges the table), but then immediately proceeds to the php script!
Below is the code between the head tags but only for field-1 for now!
