如何在jstree实例中添加分支(即具有未知级别子节点的节点)。
// example of a branch (with one level)
var branch = {
"data":"Folder 1",
"attr":{"rel":"Layer","elt":1},
"state":"closed",
"children":[
{
"data":"Item 4",
"attr":{"rel":"File 1","elt":2},
"state":"",
"children":null
}
]
};
并在jstree实例中添加此分支:
// -1 means root
$.jstree._reference('#tree').create_node(-1, 'last', branch, false, false);
但它失败了!孩子们没有被创造出来。

我的解决方案是手动和递归地创建所有节点:
function LoadElement(node, branch) {
data = {
data: branch.name,
attr: branch.attr,
state: branch.state
};
var node = $.jstree._reference('#tree').create_node(
node, 'last', data, false, false
);
if (typeof branch.children === 'undefined') return false;
for (var i=0; i<branch.children.length; i++) {
LoadElement(node, branch.children[i]);
}
}
// -1 means root
LoadElement(-1, branch);
