Select ids from jquery element array

Question

In the following jquery expression, I select an array of elements:

selectedSupplierIds = $('.supplierListCheckbox:checked');

I need to select identifiers from these elements. Can I do this without creating an array and pushing identifiers in a for loop?

You can use .map()to get an array of something based on the choice of an object ... in this case, you just need to get .idfrom each, for example:

var arr = $('.supplierListCheckbox:checked').map(function() { 
            return this.id; 
          }).get();
