jQuery check if an input is type checkbox?

$("#myinput").attr('type') == 'checkbox'

You can use the pseudo-selector :checkbox with a call to jQuery's is function:

$('#myinput').is(':checkbox')

>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">
>>> a.type
"checkbox"

Or, more of the style of jQuery:

$("#myinput").attr('type') == 'checkbox'
