有关javascript 获取checkbox复选框的实例数不胜数。js实现：
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);/*获取选中的选项*/
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);} www.jb51.net}
