How can you apply a jQuery event handler to act only on the div the user is in? -

-

here's i'm trying do, have several multiple choice questions set using same html code, same class name (a div question 4 paragraphs within div answer choices).

i want use jquery assign class called 'selected' answer choice (paragraph) user clicks on. , once they've clicked on answer choice, turn off click event question only. i'm not sure how apply div user clicking in , not entire page. here's have:

$(document).ready(function() {     function selecting() {         $('.choices p').on('click', function() {             $('.choices p').removeclass('selected');             $(this).addclass('selected');         });          $('.submit').click(function() {             $('.choices p').off('click');         });     };      selecting(); });

you can use .closest() find current .choices element , target p element element like

$(document).ready(function() {      function selecting() {      $('.choices p').on('click', function() {        $(this).closest('.choices').find('p').removeclass('selected');        $(this).addclass('selected');        });        $('.submit').click(function() {        $(this).prev('.choices').find('p').off('click');      });    };      selecting();    });
