如果在js.erb中确认

Question

I need something like this to work:

Show.erb.js:

if (confirm('Delete cart?')) { 
  <%@current_cart.reset%>
  $('.cartbadge').replaceWith('<%= j render :partial => "layouts/cartbadge"%>');
}

but the erb portion of the code is always excecuting

any ideas?

Answer 1

Because the code <%@current_cart.reset%> will be executed when the erb be interpretered.

You have to use ajax like:

if (confirm('Delete cart?')) { 
  $.post('<%= reset_cart_path(@current_cart) %>', function() {
      $('.cartbadge').replaceWith('<%= j render :partial => "layouts/cartbadge"%>');
  });
}
