Event.Observe on Radio Button in Radio Button List
My HTML:
------------------------------
<form id="someForm">
<input type="radio" id="myRadio_1"
name="myRadio" />
<label for="myRadio_1">Radio 1</label>
<input type="radio" id="myRadio_2"
name="myRadio" />
<label for="myRadio_2">Radio 1</label>
<input type="radio" id="myRadio_3"
name="myRadio" />
<label for="myRadio_3">Radio 1</label>
</form>
My Javascript:
---------------------------------
Event.observe(''myRadio_3'', ''click'',
function() {alert(''some logic goes
here'');});
My Issue:
---------------------------------
I am having an issue with an event getting attached to an entire radio
button list, and not a single radio button when using Event.observe.
Note that using Event.observe will create a click event handler for
each radio button in the list, whereas, manually attaching the onclick
handler within the HTML itself (i.e. onclick="alert(''some logic
goes
here);" ), functions correctly.
Is this an issue with Prototype, or my usage? Any suggestions?

Re: Event.Observe on Radio Button in Radio Button List
I am not seeing the error you describe here. It only triggers if I click on the third radio, never when I click on the other two. Is that in fact what you wanted? What browser are you in when you get the alert from clicking any of the three radios?

I''m seeing "normal" behavior, just like Walter described. Which prototype version and browser are you seeing this with? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
