How can I make a javascript variable and use it with jQuery

Question

How can you make a javascript variable and use it with jQuery?

I use the following command unsuccessfully in trying to get the POST data out of the var answer. I can access the variable in HTML by $_POST['answer'].

var answer = $('#answer').val();

I use this variable in this code

jQuery('div.answer_' + $answer + ' a.delete_answer')
           .live('click', function(){

You should be doing:

var $answer = $('#answer').val();

You have a '$' in your selector. You would have to remove the '$' in the selector if you don't want a $ in your variable.
