我有一个像这样的json :(这是用于通过ajax加载treeview的treeview jquery插件）
[
{
"text": "1. Pre Lunch (120 min)",
"expanded": true,

{
"text": "1.2 jQuery UI - A step to richnessy (60 min)"
}
]
},
{
"text": "2. Lunch (60 min)"
},
{
"text": "3. After Lunch (120+ min)",
"children":
[
{
"text": "3.1 jQuery Calendar Success Story (20 min)"
