.attr('checked','checked') does not work

Question

I am trying to check radio. Neither the following works:

[edit]

$(\'selector\').attr(\'checked\',\'checked\');
$(\'selector\').attr(\'checked\',true)         


        

Answer 1

I don't think you can call

$.attr('checked',true);

because there is no element selector in the first place. $ must be followed by $('selector_name'). GOod luck!
