Changing "checked" Value Of Radio Button Within Function?
Apr 29, 2010
I have a set of radio buttons on a webpage. Currently they all have the same name so that when one gets clicked on, the other one is no longer checked.
Now I want to dynamically change which one is checked from within a JavaScript function.
2 Questions,
1) I assume that I will need to change them so they all have seperate names right? Otherwise how else will I be able to refer to them?
2) What would be the syntax for doing this within a Javascript function? I.e. RadiobuttonName.checked="checked"?? Something like that?
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.
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 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]
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 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 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.
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:
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:
My program generates 10 random questions with random wrong answers in radio and one correct answer also in radio. When I click checkAnswer it should check the right answer and compare to the user provided answer. Please check out isCorrect() function (and see comment). I tried diff things and couldn't get the value out from the radio checked value.

how to reset both my text boxes when I click a different radio button so that I can give another value in the textbox area. I am trying to do it without a reset button. I am just confused with the process of resetting the values of both the text boxes in the code. I feel like the answer is to put it inline in the <input> tag...
I want that a <div> element will show when yes is selected and when no it should be hidden. For show and hind i will use the functions from the jQuery UI. But I don't find a way to call the hide / show function when the selection change.
The radio selection: <input type="radio" name="lang_anz" value="1"> Yes<br> <input type="radio" name="lang_anz" value="0" checked="checked"> No<br> When I understand the documentation I can request the current value from the radio with: <script type="javascript"> $('input:radio[name=lang_anz]:checked').val(); </script>But how i can now call the show / hide function when I change the selection?
I am building an online survey using a survey creation tool which allows me to incorporate javascript for additional functionality. However, I am new to javascript so would appreciate any help that you could provide me with.
I have question types like agreement scales, where the respondent sees a list of statements and has to rate each one by clicking on a radio button. The source code of the matrix table looks like this:
[Code].....
This code works as intended; however, as you can see, it loops through all the radio buttons when one is clicked. Is there a way to accomplish this without looping through all the radios, and thus make the script run faster?
Also, I have read that the addEventListener function does not work for older versions of IE. Is there a simpler alternative?
if radio button checked display div #something else display nothing if un checkedcurrently I have this and it works but when I click another radio option the div that was activated before stays there. Want a div to show only if certain radio button is checked and if not checked to hide.
