Validating A Radio Button That Has A Field Name With A ^ In It

May 2, 2005

The application I'm helping develop is about 10 pages long and allows users to move back and forth, updating previous selections. Certain pages use Javascript to check current selections and show/hide divs based on those selections. Most of these fields are radio buttons and use simple onClick calls. However, one of these requires that 2 fields be checked for a specific value and if they are both true, display a div.

One problem though... for other reasons these form field names all begin with either a "r^" or a "t^" signifying it as either a text field or radio button. I can get the check to work fine without the "r^" but with it I'm lost. The carrot seems to be causing problems for me and I've tried many different combinations of things to get it to work. Code:

Validating A Form Field If Radio Button Is Checked

Dec 2, 2004

I have a form that makes visible a text field when a specific radio button is checked. That works. Then I validate to see if a radio button is checked before I let the form be submitted. That works.

BUT - I cannot seem to get it to validate the form field that is made visible to see if it has content or at least the proper content when the form is submitted. Can you tell me what I am doing wrong please?

I can give more info on what kind of validation I want done if needed, but I think my code speaks for itself Code:

Populate Text Field With Radio Button Value

Jan 3, 2010

If the user selects the early bird special for member (at 100.00) it populates the text field with the value for that row. Or, if the user selects regular registration for non-member it sets the early bird text field back to 0.00 and populates the text field with he value for the regular expression code. At the same time it populates the total field with the total price. I hope this makes sense. How can I accomplish this using JavaScript or jQuery? The text fields are read only. The table is listed below.

Table code:

Jquery :: Radio Button Auto-Fill Another Field

Jul 27, 2011

I'm pretty new to coding. I have a form with two radio buttons to choose from. I would like a custom javascript function (fillShowTypeCost) to automatically update a text field with the correct amount of money, based on which radio button is selected. I originally had this form done with checkboxes and it worked just fine. Since I switched to radios, I am completely lost. I have tried using an array search to determine which value is selected, but I must be doing something wrong, because it isn't working. My codes are below. (The PHP end of things are working great.)

My PHP/HTML Code:
//Radio Button 1:
<input name="showtype" type="radio" id="showtype" value="basic" <?PHP print $basic_status; ?> onclick="fillShowTypeCost(this.form)"> Basic Slideshow

//Radio Button 2:
<input name="showtype" type="radio" id="showtype" value="lovestory" <?PHP print $lovestory_status; ?> onclick="fillShowTypeCost(this.form)"> Love Story

//Text field to be auto-updated
<input name="showtype_cost" type="text" id="showtype_cost" value="<? echo $row_settings['showtype_cost']; ?>">

Script To Highlight Text Field With Radio Button Click?

Jul 12, 2009

I am doing donation script. Here is my script so far

<script type="text/javascript">
<!--//
function chkDonation(){
var form = document.forms[0]; // FORM NAME OR PLACE IN FORMS COLLECTION //;
var amount = form['OtherAmount']; // TARGETTED INPUT NAME ( OtherAmount ) //;
amount.style.visibility = 'hidden';
for(var i=0, input=form.getElementsByTagName('input'); i<input.length; i++){
if(input[i].type.match(/radio/i) && input[i].name.match(/DonationAmount/i)){
if(input[i].value.match(/Other/i)){
input[i].onclick = function(){
amount.style.visibility = 'visible'; .....

I have pretty much completed my script but now what I want it to do is to add more forms/field when the "Other" radio button is selected. So when the Other button is checked, I want the script to display more fields/forms below. Only when the "other" button is selected. When "other" selected the script should display fields like "cheque", "cash", "Payment" etc.

JQuery :: Pass Radio Button Selection To Hidden Div And Then Show Div List From Chosen Radio Button?

Mar 16, 2010

I am a PHP programmer and new to Javascript and jQuery and I have tried about 20 examples/tutorials and cannot seem to get even close to what I want.I have a form (PHP/MySQL) with a list of subjects I got from my database, and then create a set of radio buttons from that list. And based on what radio button they select, I need to pass that variable to a div (at least that's what I want to use) and then show a list of videos that match the radio buttons value. I don't care if its a get or post or other.I tried to use GET or POST so I can use that value for my PHP/MySQL lists.I am open to any suggestions/tutorials, etc.

Only Validating One Field At A Time In A Multi Field Form?

Aug 17, 2010

my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:

//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()

Program A Radio Button To Open An "invisible" Input Field?

Aug 24, 2011

I've learned HTML and CSS pretty thoroughly.I think I have most of the Javascript basics down as far as definitions, but I'm getting hung up on the actual coding.I'm working on an information request form for my fiancee's business site. In it, I want to have options that users select via radio buttons. Rather than having additional input fields static on the page, I would like to program some of the radios, when clicked, to open a previously unseen option where users will then be able to type in the necessary information.More specifically, since she only works in two states, I want a third option of "other," which,when opened, will allow the user to input any other state.Then, should the radio be deselected or reset, the field would disappear again.

If my understanding is correct, I think I will need to use a javascript function in the header, an HTML "div" section with ID, "onclick" and "offclick" events in the button mark-up, and the specific javascript code to call the function (getElementById?).
