1. ng-repeat实现下拉框：
select下拉框里option组装成下拉框，这里利用ng-repeat指令来创建
实现源码
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>AngularJS之下拉框（方式二）</title> <script type="text/javascript" src="../js/angular.min.js" ></script> <script> var app = angular.module("secondApp",[]); app.controller("secondCon",function($scope){ $scope.trees = ["松树","樟树","枫树","枣树","桃树"]; }); </script> </head> <body> <div ng-app="secondApp" ng-controller="secondCon"> <select style="width: 200px;"> <option ng-repeat="tree in trees">{{tree}}</option> </select> </div> </body> </html> |
2.ng-option指令使用很简单，只需要绑定两个属性：
一个是ng-model用于获取选定的值；
另一个是ng-options用于确定下拉列表的元素数组。
<select ng-model="engineer.currentActivity" class="form-control" ng-options="act for act in activities"></select>
上面这条语句就是把选择的值与engineer.currentActivity进行双向数据绑定，然后列表中的选项是activities中的每一个值。数据如下：
$scope.engineer = {
name: "Dani",
currentActivity: "Fixing bugs"
};
$scope.activities =
[
"Writing code",
"Testing code",
"Fixing bugs",
"Dancing"
];
在angular中实现下拉框的两种方式 ng-repeat和 ng-option
