數據是數組

設置默認值
如果需要設置默認的選項,可以先設置一個參數:
$scope.item = 2016; $scope.years = [2014, 2015, 2016];
對象數組方式
數據是對象數組
$scope.sites = [ {site : "baidu", url : "https://www.baidu.com"}, {site : "163", url : "http://www.163.com"}, {site : "sina", url : "http://www.sina.com"} ];
頁面元素
<select ng-model="s.site" ng-options="s.site as s.site group by site.group for s in sites"> </select>
設置默認值
如果需要設置默認的選項,可以先設置一個參數:
$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"} ];

數據是對象數組
$scope.cars = { car1 : {brand : "BYD", model : "Y50", color : "red"}, car2 : {brand : "CC", model : "HF", color : "white"}, car3 : {brand : "JL", model : "JL10D", color : "black"} };
頁面元素
<select ng-model="myCar" ng-options="y.brand for (x, y) in cars"> </select>
設置默認值
如果需要設置默認的選項,可以先設置一個參數:
$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"} };
