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 n
