json - 如何在以数字为键的 JSON 数据上使用 ng-repeat？

Question

我想用 ng-repeat 来显示数据表
以这样的 JSON 格式提供

{"name":"Aruba","code":"ABW","1960":54208,"1961":55435},
{"name":"Afghanistan","code":"AFG","1960":8774440,"1961":8953544}

但是我下面的代码似乎不适用于 {{ country.1961 }}。

<table>
      <tr>
        <td>Country name</td>
        <td>1960 population</td> 
        <td>1970 population</td>
        <td>1980 population</td> 
        <td>1990 population</td>
        <td>2000 population</td> 
        <td>2010 population</td>
        <td>Percentage growth between 1960 and 2010</td>
      </tr>
      <tr ng-repeat="country in countries">
        <td>{{ country.name }}</td>
        <td>{{ country.1961 }}</td>

      </tr>
    </table>

当我删除 <td>{{ country.1961 }}</td>一切正常。
我该如何解决？

谢谢!

Answer 1

{{country.1961}}对我来说很好用，检查这个 JSFiddle ,
但最好你可以使用 括号表示法 而不是点符号时

键是完整的数字，如“1985”

键包含空格，如“我的地方”

JSFiddle

 <table border='1'>
        <tr>
            <td>Country name</td>
            <td>1960 population</td>
            <td>1970 population</td>
            <td>1980 population</td>
            <td>1990 population</td>
            <td>2000 population</td>
            <td>2010 population</td>
            <td>Percentage growth between 1960 and 2010</td>
        </tr>
        <tr ng-repeat="country in countries">
            <td>{{ country.name }}</td>
            <td>{{ country['1961'] }}</td>
        </tr>
    </table>
