js는 체크박스 체크박스 인스턴스_javascript 기술로 선택된 옵션을 얻습니다.

체크박스를 얻기 위해 자바스크립트를 사용하는 예는 셀 수 없이 많습니다.
Node.js 구현:

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);
