Jquery element list concat by separator

Question

I have a checkboxlist control and would like to get all the checkbox values that are checked concatenated into a string separated by '-'. Is there any functions for this? Ex:

$('#checkboxes input[type=checkbox]:checked').concat('-');

Answer 1

I think your best bet is

$('#checkboxes input[type=checkbox]:checked').map(function() {
  return $(this).val();
}).get().join('-');

Basically, you're applying a function to each item that returns its value. Then you assemble the result into a string.

Answer 2

Check out this previous post. Perhaps using the map() function will work for you.

$('#checkboxes input[type=checkbox]:checked').map(function() {
  return $(this).val();
}).get().join('-');

Answer 3

I think you want to look at jQuery's .map() functionality (not tested):

$('#checkboxes input[type=checkbox]:checked').map(function() {
  return $(this).attr('value');
}).get().join('-');
