Answer 1

Something like this should work.

var inputs = document.getElementsByTagName("input"); 
var checks = [];
for (var i = 0; i < inputs.length; i++) {  
  if (inputs[i].type == "checkbox" && inputs[i].checked) {  
    checks .push(inputs[i]);  
  }  
}  

using jQuery you could do this:

var checks= $("input:checkbox:checked");

Pure Javascript answer

var formelements = document.forms["your form name"].elements;
var checkedElements = new Array();
for (var i = 0, element; element = formelements[i]; i++) {
  if (element.type == "checkbox" && element.checked) [
    checkedElements.push(element);
  }
}

Jquery Answer

$("input:checked")

Does this look like a solution to your issue? Parse page for checkboxes via javascript

Basically, you'd get the element for your <input type="checkbox"> tag and verify whether or not the checked attribute evaluates to true.

Note: I'm unsure if my response should be a comment or an answer -- this almost looks like a duplicate question?
