I have multiple forms on my website. Some of them have a checkbox which is checked by default, whereas others are unchecked by default. I'm trying to figure out how I would detect whether or not the checkbox is checked, and if it is checked, disable certain fields (not necessarily all fields), and then toggle it back and forth as I check or uncheck the box..I found this code:

If A Check Box Is Or Not Empty - Allow User To Have One Box Checked At Any Time In A Form

Mar 31, 2009

I'm trying to figure out with Java Script how I would have Java Script check and see if a check box is or not empty. The goal is to only allow the user to have one box checked at any time in a form. That means, if they click on another one and there is already one checked, it would uncheck the one that was checked and make the one that the person checked on next checked.

Simple Way To Check If Form Elements Have Changed

Oct 12, 2007

I have a form with many fields... the fields are getting values from a
database.

I've tried onunload to just submit the form regardless of changes or
not but onunload and submit isn't working for me. Now I need some
type of event that will fire when a user tries to navigate from a page
to check to see if anything has changed and if so prompt them
(confirmation) to take action or not.

I know that the reset button only takes away anything that was added
to fields after the load so there must be some way to use the logic of
reset to simply check to see if fields have changed, right?

Show/hide Elements Of A Form Based On Drop Down Box Selection

Feb 13, 2006

I am setting up a contact form, and want to have a drop down box with a handful of options. Clicking one option should display fields to input username & password, whereas all others will not. So far, I've tried and (replacing 'none with 'block' for the option that is supposed to show the input fields) but neither does what I need it to. I'm fairly new to javascript, just muddling my way through with the aid of tutorials.

JQuery :: Show/hide Form Elements Based On Radio Button Selections ?

Mar 17, 2011

I have a set of radio buttons on my pricing page:

And a corresponding text_field input element div I'd like to display based on which radio button the user selects:

When the page loads, I'd like to see:

When the user clicks on a (different) radio button, or clicks one for the first time, I'd like whichever div is currently showing to be hidden, and the newly selected one to be shown.

Right now I have jQuery code at the bottom of my page that looks like this:

For each of the four options.

When the page loads, the correct div is shown, and when I select a new button, the new div is shown, but the already showing one isn't hidden.

I've read some posts that suggest using change() instead of click(), but others indicate that's problematic in IE.

Check All But One Of Them To Determine If Any Of Those Have Been Checked?

Nov 21, 2010

I have a form with several types of checkboxes, and I'm trying to check all but one of them to determine if any of those have been checked. I do not want to check 'all', but I want to see if any of the 'check_' or 'check2_' checkboxes have been checked. There are a variable number of checkboxes, so this is just an example with two of each. Set 1 and Set 2 will always have the same number of checkboxes as each other, though.

JQuery :: Show / Hide Elements Or Remove / Add Elements Based On Radio Selection By User?

Mar 14, 2010

I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:

<input name="terms_usr" type="radio" id="terms_usr_1" value="1"/>
<label for="terms_usr_1">Credit Card</label>
<input type="radio" name="terms_usr" id="terms_usr_2" value="2"/>
<label for="terms_usr_2">C.O.D</label>
