我的控制器中有以下数组数组（script.js文件）：
angular.module('myApp', [])
.controller('oneController', ['$scope', function($scope) {
$scope.countries = [{
"name": "Aruba",
"code": "ABW",
"1960": 54208,
}];
在我的index.html文件中，我正在运行ng-repeat以在1960年显示包含国家/地区名称，代码和人口的表格。
<body ng-app="myApp">
<h1>Challenge Three</h1>
<div ng-controller="oneController">
<table>
<tr ng-repeat="country in countries">
<td>{{ country.name }}</td>
<td> {{ country.code }}</td>
<td> {{ country.1960 }}</td>
</tr>
country.name和country.code显示在表格中，但country.1960则没有。是否有一定的语法我必须用于“1960”以使其正常工作？
答案 0 :(得分：2)
您需要使用括号访问它：
{{ country["1960"] }}</td>
答案 1 :(得分：-2)
您还应该能够使用以下内容：
.data
str: .asciiz "\n Please enter the number of items you are purchasing (should be less than or equal to 20): "
str1: .asciiz "\n Sorry too many items to purchase! Please enter number of items you are purchasing"
str2: .asciiz "\n Please enter the price of item "
str3: .asciiz "\n Please enter the number of coupons that you want to use. "
str4: .asciiz "\n Too many coupons! Please enter the number of coupons that you want to use."
str5: .asciiz "\n Please enter the amount of coupon "
str6: .asciiz "\n This coupon is not acceptable"
str7: .asciiz "\n Your total charge is: $"
str8: .asciiz "\n Thank you for shopping with us."
str9: .asciiz ":\t"
