我無法將CheckBox設置爲對具有子節點的節點取消選中[「jstree-unchecked」]。當我使用螢火蟲來確定前端的節點類時，它顯示「jstree-undetermined」。我真正想要的是「jstree-unchecked」成爲類，因爲這是我從服務器傳遞過來的。無法將jstree複選框節點設置爲從JSON取消選中
以下是我使用JSON進行的AJAX調用。我還添加了從服務器獲取的JSON數據。我在服務器端格式化JSON數據的方式有什麼問題嗎？
對於以下示例「Dogs」節點導致問題。雖然「狗」的兒童未經檢查，節點類未受到任何檢查;我看到「狗」節點被選中。任何建議修復或改進代碼是不勝感激。
$(function() {
$("#idTOC").bind("loaded.jstree", function (e, data) {
data.inst.open_all(-1); // -1 opens all nodes in the container
})
.jstree({
"json_data": {
"ajax": {
"url": "http://localhost/eSiriusAjax/jqTOC.wc",
"aync": false,
"data": function (n) {
return { id: n.attr ? n.attr("id") : 0 };

$("#idTOC").bind('before.jstree', function (event, data) {
if ((data.func === 'check_node') || (data.func === 'uncheck_node')) {
event.stopImmediatePropagation(); //stops changing select/deselect when clicked
return false;
}
});
});
