jQuery - Trouble passing a variable into input:radio[name]

Question

I'm having trouble passing a variable in the following

var whichRbClicked = $('input:radio[name=RBname]:checked').val();

where RBname is the variable.

Any help or advise would be MUCH appreciated. TIA

Answer 1

Should be:

var whichRbClicked = $('input:radio[name=' + RBname + ']:checked').val();
