炎热的夏天过去了，凉爽的秋天来了。它是一个收获的季节，也是各种水果最多的时候，红艳艳的苹果扒开绿叶往外瞧；小红灯笼似的枣子挂满枝头；像紫玛瑙的葡萄一串串地挂在葡萄架下，真迷人呀！
数组方式
数据是数组
$scope.years = [2014, 2015, 2016];
页面元素
<select ng-model="item" ng-options="item as y for y in years"> </select>
设置默认值
如果需要设置默认的选项，可以先设置一个参数：
$scope.item = 2016; $scope.years = [2014, 2015, 2016];
对象数组方式
数据是对象数组
$scope.sites = [
{site : "baidu", url : "https://www.baidu.com"},
{site : "163", url : "http://www.163.com"},
{site : "sina", url : "http://www.sina.com"}
];
页面元素
<select ng-model="s.site" ng-options="s.site as s.site group by site.group for s in sites"> </select>
设置默认值
如果需要设置默认的选项，可以先设置一个参数：
$scope.site = "163";
$scope.sites = [
{site : "baidu", url : "https://www.baidu.com"},
{site : "163", url : "http://www.163.com"},
{site : "sina", url : "http://www.sina.com"}
];

$scope.cars = {
car1 : {brand : "BYD", model : "Y50", color : "red"},

car3 : {brand : "JL", model : "JL10D", color : "black"}
};
页面元素

$scope.site = "BYD";
$scope.cars = {
car1 : {brand : "BYD", model : "Y50", color : "red"},
car2 : {brand : "CC", model : "HF", color : "white"},
car3 : {brand : "JL", model : "JL10D", color : "black"}
