Radio group and Previously selected

[sapras]

Hello Folks

I have a radio group. When I click a radio button I would like to know the previously selected radio button within that group. Say for example I've a radio group with elements 1, 2, 3, 4, 5. By default one of them will be checked. Say 5. Then when I click on 1 how do I know the value of previously selected radio button.

Any help would be highly appreciated.

TIA

You will have to keep track of this by assigning an onclick handler to each radio button to store a reference to the newly checked one in a variable.

This variable will need to be set on page load to the default radio button.

Hope this helps,
Dan

Thanks Dan

But I've loads of radio groups on the form and all of them are generated dynamically. The number of radio groups vary based on some parameters in the form. So how do I store the default value for each radio group in variables ?

On page load, loop through all radio groups, and then find the checked item (if there is one) for each of those. How you store them is up to you - personally, I'd use a hash map / associative array with the key being the radio group name.

Hope this helps,
Dan

Thanks Dan !

I thought there would be an easy way to process on the fly for the previously selected radio. Never mind I shall walk in your path....Thanks again for the replies.
