有关javascript 获取checkbox复选框的实例数不胜数，下面的这个示例，纯js实现的

var form = document.getElementById("form2");var field = form.elements["test2"];var option = Dining.getSelectedOption(form, field);var message = "";for (var i = 0, len = option.length; i < len; i++) {message += "Select id:" + option[i].id + "\nSelected name:" + option[i].name + "\nSelected value:" + option[i].value + "\n\n";}alert(message);getSelectedOption: function (selectform, selectionfield) {var result = [];var option = null;for (var i = 0; i < selectionfield.length; i++) {option = selectionfield[i];if (option.checked) {result.push(option);}}return result;}<form id='form2'><label>排序：</label><input id='aaaaa' type='checkbox' name='test2' value='1'><label for='aaaaa'>月销量</label><input id='bbbbb' type='checkbox' name='test2' value='2'><label for='bbbbb'>评分</label><input id='ccccc' type='checkbox' name='test2' value='3'><label for='ccccc'>优惠</label> <br style='clear:both'><label>分类：</label><input id='ddddd' type='checkbox' name='test2' value='4'><label for='ddddd'>商务套餐</label><input id='eeeee' type='checkbox' name='test2' value='5'><label for='eeeee'>凉菜</label><input id='fffff' type='checkbox' name='test2' value='6'></form>",
