json="["
json=json&"{""id"":""1"",""pId"":""0"",""name"":""张三"",""open"":""true""},"
json=json&"{""id"":""2"",""pId"":""0"",""name"":""李四"",""open"":""true""},"
json=json&"{""id"":""3"",""pId"":""0"",""name"":""王二"",""open"":""true""},"
json=json&"{""id"":""5"",""pId"":""4"",""name"":""赵六"",""open"":""true""},"
json=json&"{""id"":""4"",""pId"":""1"",""name"":""刘七""}"
json=json&"]"
response.Write(json)
