ng-option指令使用很簡單，只需要綁定兩個屬性：
一個是ng-model用於擷取選定的值；
另一個是ng-options用於確定下拉式清單的元素數組。
1、問題背景
一般情況下，select下都會有option，但是AngularJS中有指令ng-options，就可以實現select下拉框
2、實現源碼
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>AngularJS之下拉框（方式一）</title> <script type="text/javascript" src="../js/angular.min.js" ></script> <script> var app = angular.module("selApp",[]); app.controller("selCon",function($scope){ $scope.options = ["第一季度","第二季度","第三季度","第四季度"]; }); </script> </head> <body> <div ng-app="selApp" ng-controller="selCon"> <select ng-model="selectedName" ng-options="x for x in options" style="width: 180px;"> </select> </div> </body> </html>
3、問題說明
<select><option></option></select>
利用指令ng-options，可以省略<option></option>
以上所述是小編給大家介紹的AngularJS使用ng-options指令實現下拉框，希望對大家有所協助，如果大家有任何疑問請給我留言，小編會及時回複大家的。在此也非常感謝大家對雲棲社區網站的支援！
