Replyinstead of the i iterator I would just use values.push($(this).val()); in the loop, just my opinion
jQuery and checkboxes, the complete guide.
jQuery is a great framework but sometimes the jQuery.com documentation is not enough to answer all your questions.
Here is a list of pretty much everything you can do with checkboxes.
Selecting / Unselecting a checkbox
// Check a checkbox $('input[name=acheckbox]').attr('checked', true); // Uncheck a checkbox $('input[name=acheckbox]').attr('checked', false);
Selecting / Unselecting all checkboxes
// This will select all checkboxes $("input:checkbox").attr('checked', true); // This will unselect all checkboxes $("input:checkbox").attr('checked', false);
Verifying if a checkbox is selected
// this will return true is the checkbox is checked, if not it will return false. $('input[name=acheckbox]').is(':checked')
Getting a list of selected checkboxes
There are several ways to get a list the of selected checkboxes, here is my take on it.
// Extend jQuery with custom method jQuery.fn.getCheckboxValues = function(){ var values = []; var i = 0; this.each(function(){ // push values into array values[i++] = $(this).val(); }); // return array of selected checkboxes return values; } var arr = $("input:checked").getCheckboxValues(); alert(arr); // this would alert an array containing the values of the selected checkboxes
