tree没有形成树形结构

鸡胸肉终结者

后台返回的数据是这样的:{"data":
[{"id":"100001","name":"USA","pid":"2"},
{"id":"100003","name":"New York","pid":"100001"},
{"id":"100005","name":"New York","pid":"100003"},
{"id":"100007","name":"California","pid":"100001"},
{"id":"100009","name":"Los Angeles","pid":"100007"},
{"id":"100011","name":"West Hollywood","pid":"100009"},
{"id":"100013","name":"Flordia1","pid":"100001"},
{"id":"100015","name":"ao","pid":"100003"}],
"err_code":0,"err_msg":"请求成功"}

tree控件已经设置好了idfield="id",textfield="name",parentfield="pid"和datafield="data",但全部都显示在了同一级没有形成树形结构

dforce

设置resultAsTree="false"
