jQuery see if any or no checkboxes are selected

Question

I know how to see if an individual checkbox is selected or not.

But Im having trouble with the following - given a form id I need to see if any of the check

Answer 1

You can do this:

  if ($('#form_id :checkbox:checked').length > 0){
    // one or more checkboxes are checked
  }
  else{
   // no checkboxes are checked
  }

Where:

• :checkbox filter selector selects all checkbox.
• :checked will select checked checkboxes
• length will give the number of checked ones there
