Penggunaan senarai lungsur turun dengan mudah
ng-option sangat mudah digunakan Anda hanya perlu mengikat dua atribut:
Salah satunya ialah ng-model yang digunakan untuk mendapatkan nilai yang dipilih;
<select ng-model="engineer.currentActivity" class="form-control" ng-options="act for act in activities"></select>
$scope.engineer = { name: "Dani", currentActivity: "Fixing bugs" }; $scope.activities = [ "Writing code", "Testing code", "Fixing bugs", "Dancing" ];
<html ng-app="myApp"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script src="http://apps.bdimg.com/libs/angular.js/1.2.16/angular.min.js"></script> <link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css"> <script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </head> <body> <div ng-controller="EngineeringController" class="container"> <div class="col-md-12"> {{engineer.name}} is currently: {{ engineer.currentActivity}} </div> <div class="col-md-4"> <label for="name">Choose a new activity:</label> <select ng-model="engineer.currentActivity" class="form-control" ng-options="act for act in activities"> </select> </div> </div> <script type="text/javascript"> var myAppModule = angular.module("myApp",[]); myAppModule.controller("EngineeringController",["$scope",function($scope){ $scope.engineer = { name: "Dani", currentActivity: "Fixing bugs" }; $scope.activities = [ "Writing code", "Testing code", "Fixing bugs", "Dancing" ]; }]); </script> </body> </html>
$scope.activities = [ { id: 1, type: "Work" , name: "Writing code" }, { id: 2, type: "Work" , name: "Testing code" }, { id: 3, type: "Work" , name: "Fixing bugs" }, { id: 4, type: "Play" , name: "Dancing" } ];
$scope.engineer = { name: "Dani" , currentActivity: { id: 3, type: "Work" , name: "Fixing bugs" } };
$scope.engineer = {currentActivity:activities[3]}
<select ng-model = "engineer.currentActivity" class="form-control" ng-options = "a.name +' (' + a.type + ')' for a in activities" > </select >
<select ng-model = "engineer.currentActivity" class="form-control" ng-options = "a.name group by a.type for a in activities" > </select >
Semua kod:
$scope.engineer = { currentActivityId: 3 }; $scope.activities = [ { id: 1, type: "Work" , name: "Writing code" }, { id: 2, type: "Work" , name: "Testing code" }, { id: 3, type: "Work" , name: "Fixing bugs" }, { id: 4, type: "Play" , name: "Dancing" } ];
<select ng-model = "engineer.currentActivityId" class="form-control" ng-options = "a.id as a.name group by a.type for a in activities" > </select >
Semua kod adalah seperti berikut:
Di atas ialah contoh kod yang dikongsi oleh editor dengan anda kerana menggunakan ngOption untuk melaksanakan senarai juntai bawah dalam AngularJS saya harap ia akan membantu anda.
