radio button "checked" does not work in Firefox


Recommended Posts



I am trying to do some coding here but found out that radio button of html form "checked" does not work in Firefox , the button remains uncheck, but it works fine in IE, anyone has the problem before and have the solution to share??


Or any other way to write "checked" for radio button which works in Fire fox??


I am using firefox 3.6





<input type="radio" name="number" value="1" checked="checked"> 1        <--- does not work in firefox (no check)


<input type="radio" name="number" value="1" checked> 1        <--- does not work in firefox (no check)

I just encountered this problem also, but found a cause and solution.


I was using radio buttons and other input elements on a page where the data was being posted via Ajax, and I did not need a form. However, the lack of a form tag caused this Firefox (4) problem i.e. checked='checked' was ignored on radio button inputs. Chrome was OK. I didn't check other browsers.


Adding a form tag to the page fixed the issue with Firefox. As inputs are supposed to be form elements, the behaviour is understandable.


Perhaps this was also the cause of the original poster's problem.
