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.)
View 3 RepliesI have been working on this for the last couple days and have made a lot of headway, but am still stuck on a spot. I have a group of checkboxes on my form that allow the user to select which items apply. I want to verify that at least one checkbox in each group has been selected before allowing them to continue. PHP requires the naming of the arrays to include the [] but jsp (for verification) doesn't like it. I read about and used the .elements method to overcome part of that problem so my for loop is now executing for the number of items in my group:
for (var i=0; i<document.form1.elements['dining_out1[]'].length; i++)
however my if statement won't execute:
if (document.form1.elements['dining_out1[i]'].checked)
even if I have checked ALL checkboxes. I have tried all the different methods I can think of to test for a checked value on each item in the array, but I can't quite figure out what I am missing.
I was wondering if I could get some assistance with something that is probably easy for even an amateur javascript coder, but, I just can't seem to get after trying every iteration of code I can imagine.The deal is, is that I'm trying to put together a PHP search form, with checkboxes for countries (USA, CAN, MEX), and a set of checkboxes for each state in each country, including an "ALL STATES" checkbox for each country.I'm trying to input form controls where, if someone checks the "ALL STATES" box for any country, it will automatically uncheck any state checkboxes for that country. However, since the checkbox name attributes need to go to PHP as an array, I can't remove the square brackets in the name (I tried escaping the characters with up to 2 backslashes, but that didn't help).When I tried referring to the checkboxes via getElementById, that also failed. My code for the script as well as the form (abbreviated for convenience and sanity's sake) is below.
<script language="JavaScript">
<!-- Begin
function Check()

I'm working on a page generated by PHP, and all the form fields are named as b[fieldname]. (e.g. <input type=text name='b[name]' value='Adam'>). Javascript seems to barf on this (document.formname.b[name].length is undefined ). Is there any way to get this to work with arrays, or do I just need to use those fields referenced in the js as non-arrays?

Why wont this work? checkFields() iF statment is failing. The select must be set to multiple.

I tried to get this to work for so long now, I have a form which will have generated fields - ultimately becoming HTML arrays, yet I can't seem to get it to work right wiht Javascript, the code is below, but JS gives me an error saying "area[0] is not defined.HTML format:
Code:
<div id="texts">
<div class="textCount">

I'm hoping that someone can help me with a question I have about javascript syntax.
I got an html page that uploads an image and some text field to a database.
What I'd like to do is modify the content of one of the textfields prior to it being submitted to the database. Specifically, I need to append the contents of one of the fields to another.
The problem that I've encountered is that the textfield name contains square brackets , ‘extra_fields[Price]'
I've identified the square brackets as being the problem by changing the textfield's name to one that doesn't contain square brackets ,extra_fieldPrice for example and the script works fine.
Unfortunately, in the real world application of this page, I can't change the textfield name.
The specific part of the html page that's giving me problems is:
i have a form with arrays, I want to sum different arrays and display the total in a array field in the form itself.i have this code
<form>
do {
$x++;
[code]....
I have the folowing string:
"url(http://www.somelocation/anaywhere/image.jpg)" stored in the variable
str_image and I want to extract the string between the brackets. I have:
ar_match=str_image.match("url([.]*)");
it returns
0=url
1=
How do I get this to work?
While trying to get a selector to work with ids that include square brackets, I searched the forum and found that I needed to escape the brackets with '\'. However, while this works with my fiddle: can't get the exact same selector to work within my page in either FF or Safari. I've triple-checked the id and it is correct; I know that jQuery is working on the page because changing the selector to$('.nameinput') gives the expected results. can't change the id because I'm working within an existing application; I know I could add a class to the input and use that as the selector instead. I'd prefer not to and would just like to figure out why this isn't working.

Does this work in all browsers?
need urgent help with javascript arrays. I need to store the checked value of the radiobutton into an array and then display the result from that array.I have created an empty array to store the input from the textbox of the form using the JS insert() function and then used show() function to display the result... but I am unable to display which option the user has selected from the radiobutton.if you look at it in the browser, and type in a name in the name textbox and click submit....it displays the result (which was stored in the inputarray) but the radiobutton doesnt work...gives.."undefined" and should give either Male or Female, depending on what the user selects.

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.

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.

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

= "text/javascript"

When I submit a form, I need to known wich checkboxes are checked. How can I do that??

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.
