具体代码如下：
<script>
//当第一层选项选定，则该选项下的第二层全部被选定
function allSelect(check_v, checkname) {
var v_item = document.getElementsByName(check_v);
var items = document.getElementsByName(checkname);
for (var i = 0; i < items.length; ++i) {
if (v_item[0].checked) {
items[i].checked = true;
}
else {
items[i].checked = false;
}
}
}
//当第二层选项全部被选定，则第一层被选定；若第二层选项至少有一个没被选定，则第一层不被选定
function singleSelect2parent(check_v, checkname) {
var v_item = document.getElementsByName(check_v);
var items = document.getElementsByName(checkname);
var childStatus = true;
for (var i = 0; i < items.length; ++i) {
childStatus = (childStatus && items[i].checked);
}
if (childStatus) {
v_item[0].checked = true;
}
else {
v_item[0].checked = false;
}
}
//全选按钮，点击全选，则所有选项被选中
function allChecked() {
var inputItems = document.getElementsByClassName("checkbox2check");
for (var i = 0; i < inputItems.length; i++) {
var checkItems = document.getElementsByName("checkbox" + (i+1));
for (var j = 0; j < checkItems.length; j++) {
checkItems[j].checked = true;
}
inputItems[i].checked = true;
}
}
</script>
