这篇文章主要介绍angularjs中select赋值ng-options配置的示例分析,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
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"}
];
Key-Vules对象数组方式
数据是对象数组
$scope.cars = {
car1 : {brand : "BYD", model : "Y50", color : "red"},
car2 : {brand : "CC", model : "HF", color : "white"},
car3 : {brand : "JL", model : "JL10D", color : "black"}
};
页面元素
<select ng-model="myCar" ng-options="y.brand for (x, y) in cars">
</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 = "BYD";
$scope.cars = {
car1 : {brand : "BYD", model : "Y50", color : "red"},
car2 : {brand : "CC", model : "HF", color : "white"},
car3 : {brand : "JL", model : "JL10D", color : "black"}
};
