有關javascript 獲取checkbox復選框的實例數不勝數。
js實現：
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);
/*獲取選中的選項*/
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);
