json中带有中括号怎么取值？

[{"fightid":3,"fightno":7,"companyId":3,"fightdate":"2019-11-15","figjiage":124,"fightcount":53,"company_name":null,"photos":null}]，这里面的值怎么区

Answer 1

var arr = [{"fightid":3,"fightno":7,"companyId":3,"fightdate":"2019-11-15","figjiage":124,"fightcount":53,"company_name":null,"photos":null}];
//比如要取fightid就是
arr[0].fightid

这个实际上是个数组，数组里面包含一个Object元素
arr[0]就是获取这个数组的第一个元素（当然你给的只有一个元素）

Answer 2

比如把json命名为arr。转成数组后取值：arr[0].fightid
