显示 JSON 对象

Question

尝试在 javascript 中显示人员变量的各个元素在控制台中显示未定义<script>var staff = {"stdinfo" :{"si": "HH01", "sn":"DAVE BAN", "sc":"HGT 1 ", "scid":"44"},"stdinfo1" :{"si": "HH16", "sn":"DEOR ORIE MAR", "sc":"JHT 3", "scid":"31"}};</script>console.log(staff.stdinfo0.si)显示未定义。我究竟做错了什么？

Answer 1

您将 stdinfo 与 stdinfo0 混淆，它缺少大括号，并且有一个额外的".

var staff = {

  "stdinfo0": {"si": "HH01", "sn":"DAVE BAN", "sc":"HGT 1 ", "scid":"44"},

  "stdinfo1": {"si": "HH16", "sn":"DEOR ORIE MAR", "sc":"JHT 3", "scid":"31"}

};
