Hi, I have observers for a group of radio buttons, an observe\_field for each radio button (I think its not possible to have one observe\_field for a group of radio buttons). Now, the problem is that when I click on one radio button, all the observers get trigerred, so the method which the observe\_field calls gets the wrong result. I just want that method to get the radio button that is clicked, which seems quite obvious, no? Any idea how to do this? Help would be greatly appreciated! Thanks, Aditya ---

You can test the value of the button group by: $(‘common-radio-button-id’).value == ‘foo’ That should at least tell you whats selected. ---

Thanks for the reply. Unfortunately the radio buttons have different id’s (though the same name). The ‘value’ is appended to the id, which makes the id’s different for all the buttons. Which is why I need to have a different observer for each button (since the observer takes the id name). Moreover, $(‘common-radio-button-id’).value doesn’t work. I get a parse error, so probably that syntax is incorrect. Also, I don’t know if the radio\_button has a “value” method. I don’t see anything about it in the Rails API. Any other ideas? > I believe radio buttons all have same id/name.

Well, I don’t conclude (1) from (2). I believe (1) simply because as I said in the reply above, the ‘value’ is appended to the id, which makes the id’s different for all the buttons. Which means that a single observe\_field won’t work for a group of button. Actually I think I made a little mistake by saying that “when I click on one radio button, all the observers get trigerred”. In fact, as one would expect, the observers that get triggered are the ones for the radio button that gets deselcted and the one that gets selected. ---

Hi Aditya, Can you tell me how to write observers with radio buttons. I am new to rails. Please send me code snippets if possible. Thanks, Nitin.

Hi Nitin, Please post the code you’re having trouble with. Or Google ‘rails observe\_field radio\_button’. Best regards, Bill
