I want to use two checkboxes to control the appearance of two blocks. The click method doesn't work well for this situation. I have tried to use the change method, but don't know how to detect which checkboxes are checked.
$(':checkbox').change(function(){
// ....
$(':checkbox:checked').each(function(){
// ???? });
});

I've been using this script (and variants that give the user different controls) for years and am positive it worked before but I just noticed that resizable is being ignored in FF 3.0.11. It is working in IE fine. I don't want the user to be able to resize the window.
Code:
function PopNada(PopNadaUrl,xW,xH)
{
var ScreenWidth=window.screen.width;
var ScreenHeight=window.screen.height;
[code]...

I have 2 checkboxes that I want to slideDown/Up a div with. I can get 1 checkbox to do it perfectly fine...however, I can't seem to find any documentation or examples of doing it with two different checkboxes.It seems like there should an "if/then" or an "or" "and" type statement to make this happen but i'm extremely new to jquery and have no idea how the syntax is structured.Problem: Need two checkboxes to show same div... div needs to show even after one checkbox is unchecked after being checked itself.Code i've use to get one checkbox to do it: (chkframe = checkbox 1 id..... chkfound = checkbox 2 id)
$("#dropdown").css("display","none");
$("#chkframe").click(function () {
if ($("#chkframe").is(":checked")) {
[code]....

I have a form frm1 . The form is generated by a "control" that is placed on
the page - I have no access to the source to modify the controls. I can
access other hidden controls within it by referencing:
ocontainer.frm1.txt1.value;
I would like to insert my own hidden control that can be posted back to to
my page so I can do something with it. How can I do this from clientside at
runtime?

In HTML documents, named forms may be referred to as named
properties of the `` document.forms '' collection, and named form
controls may be referred to as named properties of the form's
elements collection:
var frm = document.forms["formname"];
var contrl = frm.elements["elementname"];
The (string) value property of such controls can be read
directly from the element:-
var value = contrl.value;
var value = (+contrl.value); //string to number: see 4.21
One exception is where the control is a SELECT element, and
support for older browsers, such as NN4, is required:
var value = contrl.options[contrl.selectedIndex].value;
Another exception is where several controls share the same name,
such as radio buttons. These are made available as collections
and require additional handling. For more information, see:-

onchange="p_complete.disabled=!(this.selectedIndex==2)"
Which disables form element 'p_complete' is the third option is selected from this drop down. What I need to do is disable that element if the first, second or third option is selected.
Meaning something like:
onchange="p_complete.disabled=!(this.selectedIndex==0 or this.selectedIndex==1 or this.selectedIndex==2)"
...but of course, obviously this doesn't work or I wouldn't be posting here.

In a form I have an input field. It's supposed to get input form a
scanning device. Thus, the input might contain special characters (like
the Group Separator in a EAN barcode). Now, I want to manipulate a
little with the input in a javascript, but I'm not able to find the
Group Separator:
input = document.main.input.value;
var a = input.split("");
var i;
for(i=0;i<a.length;i++) {
if(/x1D/.test(a[i])) {
alert("GS");
}
}
This is a snip that parses the input, character by character, and gives
me an alert if the Group Separator (Hex: 1D) is found. But it never
matches, even if I know that the input string contains in. I have a
similar script written in Perl, an that script finds the Group Separtor.
What can I do to find the %"#¤ Group Separator??

I want to know if there is a way to automatically add a UI control to all fields of a certain type, for instance:
Lets say I have two form fields, with ID/Name of startDate ad endDate.
On a different page, I have say, 4 date fields, like Date1, Date2, Date3, Date 4.
Is there a way to have jQuery notice when fields have an ID that contains "date" and automatically add the datepicker to them?
I ask because I want to create a template with controls like this, where you simply name all form fields relatively standard things and jquery will automatically add the right controls.

I am trying to sum the "value" of multiple checkboxes who's values are all numeric, and then alert via pop-up the value of the sum when a Sumbit button is clicked. I thought I figured out how to do it using some jquery, but for some reason the Submit button doesn't fire anything.
Heres the code.
HTML Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Is there some way in a <form> tag to transfer control to a JavaScript function after completion of the submit, where the <form> and function are on the same page? I believe ONSUBMIT and similar event handlers can be used to transfer control to a function just before the submit is completed.
But, I'm looking for a way to transfer control afterwards.

In jquery how can I grab values from a forms input checkboxes? I written the code and I think I didn't properly request the object and also does the input need to have a id or a class? I have no id nor classes with these inputs just names.

Any suggestions on how the javascript below should be changed so it will work with checkboxes that have brackets in the name? (I'm using foreach in php, and can't seem to get the php to work/work correctly without using them.)

I have some checkboxes in a form that I'd like to validate (check to ensure that at least one has been ticked):
HTML Code:
<input type="checkbox" name="response[]" value="answer1" />answer1
<input type="checkbox" name="response[]" value="answer2" />answer2
<input type="checkbox" name="response[]" value="answer3" />answer3
<input type="checkbox" name="response[]" value="answer4" />answer4
The javascript below only works if I change my checkbox names to name="response" rather than name="response[]".
Code:
function validateform(){
var success = false;
for (i = 0; i < document.surveyform.response.length; i++){
if (document.surveyform.response[i].checked){
success = true;
}} return success;
}
I need to pass along multiple checkbox responses to my PHP script and therefore need to keep checkboxes named name="response[]". When I do this, I get the error "document.surveyform.response has no properties"
What change I can make to the javascript so that I can name my checkboxes name="responses[]" ?

I have checked over my code several times and cannot find what I've done wrong with my first script, which is to check/uncheck all checkboxes in a html form. Nothing is checking or unchecking, and I am seeing the "Error on this page" in IE whenever i first click one of the two buttons. Here are the steps I have taken1. I have imported the jQuery library which I have just downloaded (1.4.2 development version, 155kb) with the following code:
< script
type
= "text/javascript"

I found a script on this forum that does almost what I want from this thread: [URL]. Instead of a dropdown, I'd like to have a list of names using check boxes, so that you have the option to send an email to one or all of the people. When you choose your selections and click submit, an outlook email will pop up with your selections in the to: field.
Here's the solution using a drop down, this works (and works well), but doesn't quite do what I need :
<form name="Contact_Us" id="contact" method="post" enctype="text/plain" onsubmit = "getEml()">
<fieldset id="selection">
Who would you would like to email:
<select name = "sel">
<option value="email1@email.com" >email 1</option>
<option value="email2@email.com" >email 2</option>
<option value="email3@email.com" >email 3</option>
</select>
<input type = "submit" value = "Submit the form">
</form>
<script type = "text/javascript">
function getEml() {
var emailaddress = document.Contact_Us.sel.value;
window.location = "mailto:" + emailaddress;
}
</script>
Is there a way to use checkboxes but to do the same thing?
<INPUT TYPE=CHECKBOX NAME="name1@email.com">name 1<BR>
<INPUT TYPE=CHECKBOX NAME="name2@email.com">name 2<BR>
<INPUT TYPE=CHECKBOX NAME="name3@email.com">name 3<BR>

A web page I'm creating will allow a visitor to download a number of PDF files. A form on the page has one checkbox for each of the PDF files. I also wanted to add a checkbox to select/deselect all the PDFs.All works fine, but I also want the visitor to supply their name and email address before downloading, so I want to add another checkbox before the submit button to allow them to opt in/out of having their email address used for further mail shots.Unfortunately since the code selects/deselects all checkboxes on the form, it also ticks/unticks the opt in/out checkbox.
Is there a way - possibly by targeting the opt in/out checkbox's ID - to filter it out of this mass selection/de-selection process?I'm sure it's pretty straightforward but as I say I'm a Javascript novice.

Situation:I have a very long page divided into many sections vertical-wise marked by bookmarks, say pageX.html#s1 to s10. I need to show the section inside an iframe (iFrame1) on the mainpage (mainpage.html). I am thinking of having 4 buttons, sitting on the mainpage, to help navigate between these sections on pageX, namely NEXT, PREVIOUS, TOP, END.condition of the frame, fixed width/height, no scroll, no border.Very new to javascript but need this code to make a page work for BIZ.

I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so:
<form action="" method="post">
<input type="checkbox" name="checked[]" value="1">
<input type="checkbox" name="checked[]" value="2">
<input type="checkbox" name="checked[]" value="3">
<input type="checkbox" name="checked[]" value="4">
</form>
I use an event handler to call a function:
<input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function:
function checkall(box_name, current_state) {
all = document.getElementsByName(box_name);
action = (current_state == "checked") ? "false" : "true";
for (i = 0; i < all.length; i++) {
all[i].checked=action;
}}
The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function.
