Question

我正在为项目使用AngularJS和jQuery。当我输入输入时，ng-change正在工作..但是，当我使用jquery input.val（＆＃39; blabla＆＃39;）ng-change无效时..如何报告此更改angularjs方面？这是我的代码..申请或观看或其他？

 // Html
    <input type="text" name="city" class="city-input req-string" rel="cityCtr" value="" ng-model="city" ng-change="findWeather(city)">

    // jQuery code
    $('.city-input').val('İstanbul');

     // All AngularJS code
    var app = angular.module('weatherApp', []);

app.controller('weatherCtrl', ['$scope', 'weatherService', function($scope, weatherService) {

    function fetchWeather(city) {
        weatherService.getWeather(city).then(function(data){
            $scope.items = data;
        });
    }

    $scope.findWeather = function(city) {
        $scope.items = '';
        fetchWeather(city);
        alert(city);
    };

}]);

app.factory('weatherService', ['$http', '$q', function ($http, $q){
    function getWeather (city) {
        var deferred = $q.defer();
        var query = 'select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="'+city+'")',
            url   = "http://query.yahooapis.com/v1/public/yql?q=" + query + "&format=json&callback=";
        $http.get(url)
            .success(function(data){
                deferred.resolve(data.query.results.channel.item.forecast);
                console.log(data)
            })
            .error(function(err){
                console.log('Error retrieving markets');
                deferred.reject(err);
            });
        return deferred.promise;
    }

    return {
        getWeather: getWeather
    };
}]);

只需使用：

$('.city-input').val('İstanbul');

而不是：

SELECT /* ROUTEID */
       ROUTES.[RouteId] AS ROUTEID,       
       /* ROUTE STARTDATETIME */
       ROUTES.[DateTime] AS ROUTESTARTDATETIME,     
       /* ROUTE DESCRIPTION */                                     
       {Route}.[Description],
       /* NAME OF THE DRIVER */  
       {Driver}.[Name],         
       /* VEHICLE LICENSE PLATE */
       {Vehicle}.[Registration],
       /* QUANTITY OF STOPS */
       (SELECT COUNT({RouteStop}.[RouteId])
          FROM {RouteStop}
         WHERE {RouteStop}.[RouteId] = ROUTEID) AS STOPCOUNT,
       /* AMOUNT OF FUEL */
       (SELECT SUM(FUEL.[Value])
          FROM {GPS} FUEL     
         WHERE ROUTES.[AvailabilityId] = FUEL.[AvailabilityId]
           AND TRUNC(ROUTES.[DateTime]) = TRUNC(FUEL.[DateTime])
           AND FUEL.[EventTypeId] = @FuelEventTypeId) AS FUELAMOUNT,
       /* ROUTE ENDDATETIME */
       (SELECT ROUTEENDDATETIME.[DateTime]
          FROM {GPS} ROUTEENDDATETIME
         WHERE ROUTEID = ROUTEENDDATETIME.[RouteId]
           AND ROUTEENDDATETIME.[EventTypeId] = @RouteCompletedEventTypeId 
           AND ROWNUM = 1) AS ROUTEEND, 
       /* INITIAL MILEAGE */                         
       (SELECT INITIALMILEAGE 
          FROM (SELECT MILEAGEBEGIN.[Value] AS INITIALMILEAGE
                  FROM {GPS} MILEAGEBEGIN 
                 WHERE ROUTES.[AvailabilityId] = MILEAGEBEGIN.[AvailabilityId]
                   AND TRUNC(ROUTES.[DateTime]) = TRUNC(MILEAGEBEGIN.[DateTime])
                   AND MILEAGEBEGIN.[EventTypeId] = @MileageEventTypeId 
                 ORDER BY MILEAGEBEGIN.[DateTime] ASC
               ) 
         WHERE ROWNUM = 1),
       /* FINAL MILEAGE */                         
       (SELECT FINALMILEAGE 
          FROM (SELECT MILEAGEEND.[Value] AS FINALMILEAGE 
                  FROM {GPS} MILEAGEEND 
                 WHERE ROUTES.[AvailabilityId] = MILEAGEEND.[AvailabilityId]
                   AND TRUNC(ROUTES.[DateTime]) = TRUNC(MILEAGEEND.[DateTime])
                   AND MILEAGEEND.[EventTypeId] = @MileageEventTypeId
                 ORDER BY MILEAGEEND.[DateTime] DESC
               ) 
         WHERE ROWNUM = 1)

FROM {GPS} ROUTES

INNER JOIN {Route}
   ON ROUTES.[RouteId] = {Route}.[Id]

INNER JOIN {Availability}
   ON ROUTES.[AvailabilityID] = {Availability}.[Id]

INNER JOIN {Driver}
    ON {Availability}.[DriverId] = {Driver}.[Id]

INNER JOIN {Vehicle}
   ON {Availability}.[VehicleId] = {Vehicle}.[Id]

 WHERE ROUTES.[EventTypeId] = @RouteStartedEventTypeId

AngularJS：当我使用jquery输入.val（）时，ng-change无法正常工作
