我目前有2個jstrees都使用Types插件來定義每個節點的類型。我的問題是，當我從jstree＃1中將類型爲「Topic」的節點拖到具有「Folder」類型節點的另一棵樹jstree＃2時，它只是給我一個紅色的X.我有用「valid_children」：「Topic」 on jstree＃2多棵樹之間的Jstree Valid_children
jstree＃1工具箱。用於將某些節點拖入另一個節點。 「Always_copy」
.jstree({
"core": {
//Prevent node from being deleted when moved to the design tree
"check_callback": function (operation, node, node_parent, node_position, more) {
},
"data": {
"url": getToolTreeUrl,
"data": function (node) {
return { 'id': node.id };
}
}
},
//Enabled the drag and drop plugin with ability to drag and drop between tree
"plugins": ["dnd", "unique", "types", "ccrm"],
"crrm": {
"move": {
"check_copy": function() {
alert("Check_Copy");
},
},
},
"types": {
"#": {
"max_children": 1,
"max_depth": 2
},
"Topic": {
"valid_children": "Task"
},
"Task": {
"valid_children": "Task"
},
"Paragraph": {
},
"Dictionary_List": {
},
"Ordered_List": {
},
"Unordered_List": {
},
"List_Item": {
},
"Picture": {
},
"Video": {
},
"Table": {
},
"Note": {
},
"QHSE-Note": {
},
},
"dnd": {
always_copy: true,
is_draggable: function (data) {
return data[0].id != 0; //disallow entire toolbox being dragged
},
},
rules: {
multitree: true,
draggable: "all"
}
});
}
jstree＃2是我的文檔，從工具箱接收節點。
.jstree({
"core": {
"check_callback": function (operation, node, node_parent, node_position, more) {
var type = node.text;
var parentValue = node.parent;
if (operation == "move_node") {
asyncPost(getObjectLogicCheckUrl);
}
if (operation == "copy_node") {
asyncPost(getObjectLogicCheckUrl);
}
},
"data": data
},
"plugins": ["dnd", "contextmenu", "types"], contextmenu: { items: customMenu },
"crrm": {
"move": {
"check_copy": function() {
alert("Check_Copy");
},
},
},
"types": {
"#": {
"max_children": 1
},
"Topic": {
//"valid_children": "Task"
},
"Task": {
//"valid_children": ["Task", "Paragraph", "Dictionary_List", "Ordered_List", "Unordered_List", "Picture", "Video", "Table", "Note", "QHSE-Note"],
},
"Paragraph": {
//"valid_children": ["Paragraph", "Dictionary_List", "Ordered_List", "Unordered_List", "Picture", "Video", "Table", "Note", "QHSE-Note"]
},
"Dictionary_List": {
"valid_children": ["List_Item"]
},
"Ordered_List": {
"valid_children": ["List_Item"]
},
"Unordered_List": {
"valid_children": ["List_Item"]
},
"List_Item": {
"max_children": 0
},
"Picture": {
"max_children": 0
},
"Video": {
"max_children": 0
},
"Table": {
"max_children": 0
},
"Note": {
},
"QHSE-Note": {
},
"Folder": {
"valid_children": "Topic"
},
},
rules: {
multitree: true,
draggable: "all",
},
我想找出一種方法來鎖定哪些節點可以拖動到文檔樹中的哪裏。 IE ..類型爲「Topic」的節點只能接受類型爲「Task」的節點。
如果有人知道如何啓用類型插件在多個樹之間工作，請幫助。
