Question

i am building an estimates form and I need to send by email only the div’s with checked box. how to script it with jquery? I guess I must first get all the checked boxes and unchecked ones and eliminate from the form the correspondent div of the unchecked box.

Answer 1

You can use the :checked pseudoselector to select checkboxes that are checked:

$("input[type='checkbox']:checked");

Or to get checkboxes that are not checked:

$("input[type='checkbox']:not(:checked)");

Or to get checked checkboxes inside of your correspondent div:

$("#correspondent input[type='checkbox']:checked"); 

EDIT

So you want divs that have checkboxes, none of which are checked? This will do that

var divsWithoutChecked = 
    $("div:has(input[type='checkbox'])")
       .filter(function () { 
          return $(this).find("input[type='checkbox']:checked").length === 0 
     });
