javascript - Adding an id on to a href jquery -


i'm trying id of radiobutton added href when link clicked. tried searching google long time. maybe i'm missing because it's basic.

i have bit of code written doesn't work. help?

function productidlink() {         var url = "/bbbb/aaaaaaa/" + ('.aaasaff:radio:checked').attr('id');         $("#safad").attr("href", url)         }

looks you've forgotten $:

...  ('.aaasaff:radio:checked').attr('id')

should be

... $('.aaasaff:radio:checked').attr('id')
