Json 无法在angular 6中处理来自firebase的日期

现在我们需要从上面的字符串中读取fulldetailsdate。如何在typescript中执行此操作？

将

用于in-loop

，因为它是一个对象：

JSON.stringify(values[i].value1)=>
    {"-LJ2PhylTGjo1Li6QxP4":{"dtime":{"befor_":0,"dates":"04-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 7-08-2018","id":1,"mDay":"7","mMonth":"08","mYear":"2018","to_t":18,"weak":2},"lan":0,"lon":0},"-LJ2PtF3X9OaH-5Lv982":{"dtime":{"befor_":0,"dates":"04-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 7-08-2018","id":1,"mDay":"7","mMonth":"08","mYear":"2018","to_t":18,"weak":2},"lan":0,"lon":0},"-LJIQjbtU7Ryz-gUcxRF":{"dtime":{"befor_":0,"dates":"07-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 8-08-2018","id":1,"mDay":"8","mMonth":"08","mYear":"2018","timestampCreated":{"timestamp":1533629365655},"to_t":18,"weak":3},"lan":0,"lon":0}}

如何获取-LJ2PhylTGjo1Li6QxP4？我尝试了值[I].value1[j]。键，但它是未定义的，

j

是

-LJ2PhylTGjo1Li6QxP4

JSON.stringify(values[i].value1)=>
    {"-LJ2PhylTGjo1Li6QxP4":{"dtime":{"befor_":0,"dates":"04-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 7-08-2018","id":1,"mDay":"7","mMonth":"08","mYear":"2018","to_t":18,"weak":2},"lan":0,"lon":0},"-LJ2PtF3X9OaH-5Lv982":{"dtime":{"befor_":0,"dates":"04-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 7-08-2018","id":1,"mDay":"7","mMonth":"08","mYear":"2018","to_t":18,"weak":2},"lan":0,"lon":0},"-LJIQjbtU7Ryz-gUcxRF":{"dtime":{"befor_":0,"dates":"07-Aug-2018","from_t":14,"fullDetails":"Between 2 PM to 6 PM on 8-08-2018","id":1,"mDay":"8","mMonth":"08","mYear":"2018","timestampCreated":{"timestamp":1533629365655},"to_t":18,"weak":3},"lan":0,"lon":0}}

for (var j in values[i].value1) {
    console.log(values[i].value1[j].dtime.fullDetails)
}
