如何在json对象中使用此类型键？

Question

我正在使用第三方apis获取json对象，就像这样。

var data ={
"matches": [
{
  "unique_id": 1144995,
  "date": "2018-12-25T00:00:00.000Z",
  "dateTimeGMT": "2018-12-25T23:30:00.000Z",
  "team-1": "Australia",
  "team-2": "India",
  "type": "Test",
  "squad": true,
  "toss_winner_team": "India",
  "matchStarted": true
},
{
  "unique_id": 1153839,
  "date": "2018-12-25T00:00:00.000Z",
  "dateTimeGMT": "2018-12-25T22:00:00.000Z",
  "team-1": "New Zealand",
  "team-2": "Sri Lanka",
  "type": "Test",
  "squad": true,
  "toss_winner_team": "Sri Lanka",
  "matchStarted": true
},
],
 "type":"test"
}

但问题是，当使用每个循环数据时，获取关键字"team-1“和"team-2”值，而不是仅获取"NaN“打印选项。

var container = $("#metch_container");
$.each(data.matches, function(key, value) {

                container.append($("<option></option>")
                .attr("value",value.unique_id)
                .text(value.team-1. +" VS " + value.team-2));
            });

请帮我解决问题，谢谢！

Answer 1

如果属性名称包含无效字符，请使用value["team-x"]格式：

var container = $("#metch_container");
$.each(data.matches, function(key, value) {

                container.append($("<option></option>")
                .attr("value",value.unique_id)
                .text(value["team-1"] +" VS " + value["team-2"]));
            });

我希望这能对你有所帮助！

Answer 2

在这一行中：

.text(value.team-1. +" VS " + value.team-2));

不能通过value.team-1或value.team-2访问值，因为team-2引用

团队减2

，这里不是一个可识别的变量:您在这里可以做的是：

.text(value["team-1"] +" VS " + value["team-2"]);

首先，您的JSON无效。下面是有效的JSON

检查Here

https://jsfiddle.net/shoesheill/gjbzq7an/1/

var data = {
    "matches": [
    {
        "unique_id": 1144995,
        "date": "2018-12-25T00:00:00.000Z",
        "dateTimeGMT": "2018-12-25T23:30:00.000Z",
        "team-1": "Australia",
        "team-2": "India",
        "type": "Test",
        "squad": true,
        "toss_winner_team": "India",
        "matchStarted": true
    },
    {
        "unique_id": 1153839,
        "date": "2018-12-25T00:00:00.000Z",
        "dateTimeGMT": "2018-12-25T22:00:00.000Z",
        "team-1": "New Zealand",
        "team-2": "Sri Lanka",
        "type": "Test",
        "squad": true,
        "toss_winner_team": "Sri Lanka",
        "matchStarted": true
    }],
    "type": "test"
}

然后，如果你的密钥中有-，那么使用下面的代码

var container = $("#metch_container");

$.each(data.matches, function(key, value) {
container.append("<option>dvdfvfdv</option>")
     .attr("value",value.unique_id)
     .text(value['team-1'] +" VS " + value['team-2']);
   });
