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:
I am a newbie to jQuery and still learning the ropes. I would greatly appreciate your help in resolving the following issue: I am using jquery.validate.js plugin to validate a form.
The form has two groups of radio buttons with names ( g1 and g2 ). It also has other elements like textboxes and select boxes.
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:
I have a group 2 Radio buttons, if the user selects the 2nd Radio button then they need to enter some data into a text field... The following only works for either Radio buttons... How can I specify it to be only the 2nd Radio button?
if(!document.form.radio1.checked && document.form.q3.value=="") { theMessage = theMessage + " --> You selected no we need a reason)"; }
I am pretty new at javascript and I am trying to create a payment form that has both fields for payment by check and payment by credit card.I am wondering how I would go about having a radio button that asks the user how they would like to pay "credit card" or "check" and depending on which one they pick it shows the fields pertaining to that type of payment.the fields in the form look like this:Credit Card Fields:
The following (likely far from imperfect code), reports a value of NaN in the j4 display. I suppose the problem is I am not really passing the "checked" value of the radio button via .value ... without having to get this value via html, is there any way I can passed the checked value via html .. maybe with syntax like n4.checked.value or something.. Code:
I have a set of radio buttons each with an onclick event that has a numeric value. When the button is clicked an input box called "Total" is updated with the new value. The problem I'm having is that if a radio button is checked and one clicks on it again then the onclick event is triggered.
Is there any way to prevent the onclick event from triggering if the radio button is already checked?
I'm only validating one (Consent) radio button with this code but I need to validate multiple different questions/buttons.
<script> function getRBtnName(GrpName) { var sel = document.getElementsByName(GrpName); var fnd = -1; var str = ''; for (var i=0; i<sel.length; i++) { if (sel[i].checked == true) { str = sel[i].value; fnd = i; } } return fnd; }
function checkForm() { var chosen = getRBtnName('Consent'); if (chosen < 0) { alert( "Please choose one answer when you are asked to select a number." ); return false; } else { return true; } }
</script> <form action="congratulations_aff.php" method="post" name="congratulations_aff" onSubmit="return checkForm()"> <table border="0" cellspacing="1" cellpadding="0"> <tr> <td colspan="3">I consent to providing my electronic signature.</p></td> </tr> <tr> <td colspan="3" valign="top"> <input type="radio" name="Consent" value="Y" /> Yes <input type="radio" name="Consent" value="N" /> No
<table border="0" cellspacing="1" cellpadding="0"> <tr> <td>I consent to electronic receipt of my information reporting documentation.</td> </tr> <tr> <td valign="top"> <input type="radio" name="Consent1099YesNo" value="Y" /> Yes <input type="radio" name="Consent1099YesNo" value="N" /> No</td> </tr> <tr> <td valign="top">
For tax purposes are you a U.S. citizen, U.S. resident, U.S. partnership, or U.S. corporation? <input type="radio" name="USPersonYesNo" value="Y" /> Yes <input type="radio" name="USPersonYesNo" value="N" /> No </tr> </table> <input type="submit" value="submit" value="Submit" /> </form>
I have a form that has multiple radio button groups and i want it to validate so that if any button is selected in one group you cannot make a selection in the other groups.
i got a list of radiobutton, with differnt name. when i click on the radio button, it willpass the 'ID' into the JS function, how can i get the CHEKED radio ID and put in the hidden field first? i wan to put the all checked radio ID separated by a specified delimiter, such as in this format--> 1.2.3.4.5.6 with the delimiter '.'.bewlow is my html code :
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html > <head>
[code].....
when i onclick the radio button, i call two function. the radio buttons value is loop from the Db so it has differnet name for every row. when i clicked on the radio button, one of the calling fucntion is chkPhoto('1')--> it will pass the photoid to the fucntion. if let say got three photo or more, how can i pass the value(assign it into the hidden text field name 'photo'? i would like to assign it in this format --> 1.2.3 with the delimiter join on the checked photo value.
I need to know how to use Javascript to test if any one of a series of radio buttons has been checked. There's a catch, though: The radio buttons and their values are dynamically generated out of a database, so there's no way of knowing ahead of time how many radio buttons there will be or what the value associated with each button will be. Thus, I can't simply test the value of each button separately, nor can I use an array unless I can figure out how to count how many options there are when the page is dynamically generated. It seems like there should be any easy way!
I'm trying to dynamically set which radio button is checked with javascript. Since the radio buttons need to be named the same in order to act mutually exclusive (if you check one, the other one unchecks), I'm not sure how I can choose one to check.[code]
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() function validate_join()
I'm having a bit of trouble getting the checked radio values from my form so I can submit them via AJAX. The main problem is, I do not know what the name is going to be, and there could be any number of them. Here is a basic example of the HTML code (It is dynamically generated).
<form id="addnew"><input type="hidden" name="clientid" value="1" /> <table class="clientareatable" align="center" cellspacing="1"> <tr class="clientareatableactive"> <td>This is a test question 1</td>
I'm trying to reset a form so that no radio buttons are selected. The code works in Firefox 3.5.7, Chrome 3, and Safari 4.0.3. However, in IE 8 only the 1st radio button is correctly cleared. If I check the 2nd radio button and click the clear button, the 2nd radio button IS NOT cleared. The following HTML should reproduce the issue. Can others reproduce this? [code]...
javascript function that identifies <onmouseout> what radio button has been selected so that a message prints in a <div> further down the same page prior to submitting the page.
e.g. If Radio Button value="train" is selected
Print "You have chosen the image Train: <img src="images/train.jpg" alt="Train Image">
If Radio Button value="boat" is selected
Print "You have chosen the image Boat: <img src="images/boat.jpg" alt="Boat Image">
I have a page where I need to display 1 of 5 divs, based on the radio button that's selected. The code I'm using is from a previous page that basically did the same thing, only the user had to click on a tab, which would in turn change the style on the div from "display: none" to "". I'm assuming I can basically use the same code, but I'm not sure how to do this with radio buttons. The page I'm working with is at [URL].
Here is the code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]"> <html xmlns="[URL]"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> <style type="text/css"> .....
I have a choice of three market items and I want the value of the selected one to be sent to my form. My code is:[code]I have tried giving them different ids, I have tried replacing the id with checked="id='myitem'", I have tried getElementById('myitem.checked'), I have tried getElementbyName.In my full page I have far more radio buttons, so I don't want to do a getElementById('myitem[0].checked || myitem[1].checked etc.But I have run out of alternatives to try. Needless to say as it currently stands it gives the last radio button's value, which means it doesn't like them having the same id, but when I tried changing how the id was applied, or called - ElementByName, FF gives the error message as id is null.
I am making a quiz (for fun) and i want to find out how to check if a specific radio button is checked? what is the easiest way to check this? If i use a loop, how will i add an integer without it adding the integer during the loop?
I am somewhat a noob at js/jquery so I wasn't sure exactly how to do this. Think I just need a push in the right direction. Basically I'm trying to validate a form (jquery validation) with a couple of conditionals based on a selection box. So I have:
