Validate That User Checks A Radio Button?

Sep 9, 2009

I'm trying to validate that a user checks a radio button.

The trick is, depending on a search the user does there could be from 0-20+ buttons they could end up with. This code I have so far works if there is 0, or more than 1 button. However if there is only 1 button and they select it, it will bring up the alert that none are checked. Here is the code

Code:

function validatebutton()
{
var radio_choice = false;

JQuery :: Validate Plugin Validate Inline - Only Checks For Errors On 'submit'

Jun 3, 2011

I'm using the validation plugin [url]

I must be missing something, is there not an easy way to validate inline?

For example, I have a required text input that is given focus on page load, I would like for it to throw an error if the user moves to the next field w/o entering any data.

Right now, it only checks for errors on 'submit'.

Radio Button Validation - Form That Has 4 "required Fields" That Validate Using JS

Jan 7, 2011

I have a form that has 4 "required fields" that validate using JS. I am now trying to add a 5th "required field" (the difference is that this field is a "radio button input as opposed to a text input).

I have it working so that when the 1st radio button is selected, the form will go through. However, when the 2nd radio button is selected, it comes up with the "please fill in all required fields" error.

Here is the JS I have so far:

HTML Code:

I tried adding the 2nd radio button value like this:

HTML Code:

(document.indiv_reg.skill[0].checked =="") || (document.indiv_reg.skill[1].checked =="") But when I do that, then even when the 1st radio button is selected it comes up with the "please fill out all required fields error".

PHP Code:

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.

Radio Buttons: Preventing The OnClick Event If The Radio Button Is Already Checked

Mar 23, 2009

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?

JQuery :: Dynamically Add Radio Button - Handler To My Form On A Button Click ?

Jul 13, 2010

I am trying to produce a web form to allow wedding guests to RSVP. The form allows them to enter a name and select from a radio button whether they will be attending or not. If they select the "yes" radio button then a further pair of radio buttons are displayed for their meal preference.

They can then click a submit button or they can click another button to add another line for another guest which operates in exactly the same way. I've almost got this working, but it seems that the checkbox change handler is lost for the current guest when a new guest is added and the checkbox value is reset. I've got a feeling I'm doing something stupid but can't for the life of me figure out what.

Code (source file (renamed to .txt) also attached as I'm not sure the pasted code is too clear):
