angular.js - AngularJS Select默认值？

问题描述

AngularJS Select绑定的是对象：

$scope.cars = {car01 : {brand : 'Ford', model : 'Mustang', color : 'red'},car02 : {brand : 'Fiat', model : '500', color : 'white'},car03 : {brand : 'Volvo', model : 'XC90', color : 'black'}};

<select ng-model='selectedCar' ng-options='y.brand for (x, y) in cars'></select>

现在想给select一个默认值怎么设置呢？

问题解答

<select ng-model='selectedCar' ng-options='y.brand for (x, y) in cars></select>

$scope.selectedCar = $scope.cars.car01;

这样就是默认选中第一项

<option>--please select--</option>
