javascript - 通过 ng-click 将 ng-model 变量传递给函数

Question

我试图在 HTML 中使用选择和选项标签。数据是通过使用 ng-repeat 带来的，当用户从列表中选择一个项目并按下 get 按钮时，我想将用户从选项列表中选择的内容传递到一个函数中使用ng-点击

HTML

<ul>
 <li class="col-xs-4"><a href="#favourites">Favourites</a></li>
</ul>
<div ng-controller="favouritesController">
 <select class="col-xs-12" name="weather">
  <option ng-repeat="weatherList in weatherLists" ng-model="city">{{weatherList.place}}</option>
 </select>
 <div class="col-xs-12">
  <button type="button" name="button" class="deleFav" ng-click="getFavWeather(city)">Get</button>
 </div>
</div>

Javascript 代码

var myApp = angular.module('myApp', ['ngRoute'])

 myApp.controller('favouritesController', function($scope, $http, $rootScope, $route, $location) {
  $scope.getFavWeather = function(weatherList){
   console.log("yes yes yes")
   console.log($scope.city)
  }
 })

在选择上添加 ng-model 并在你的 ng-click 中使用它:

<div ng-controller="favouritesController">
 <select class="col-xs-12" name="weather" ng-model="citySelected">
  <option ng-repeat="weatherList in weatherLists" ng-model="city">{{weatherList.place}}</option>
 </select>
 <div class="col-xs-12">
  <button type="button" name="button" class="deleFav" ng-click="getFavWeather(citySelected)">Get</button>
 </div>
</div>
