Javascript or Jquery to check and uncheck all checkbox

Question

I have a form with a list of checkboxs. I want to create a checkAll and UncheckAll boxes for better user experience. I tried a lot of code that I got from Internet, but none

Answer 1

var form = document.getElementById('groupImportForm');
var inputs = form.elements;
var checkboxes = [];
for (var i = 0; i < inputs.length; i++) {
    if (inputs[i].type == 'checkbox') {
        inputs[i].checked =true;
    }
}

Javascript version of the example

Same thin using jQuery

$(".uncheckAll']").click(function() {
   $('.inputs').attr('checked','checked'); //add the atrribute checked
   // $('.inputs').removeAttr("checked");     //remove the attribute checked
});

Working example of jQuery
