我创建服务:
.factory('patientListBarService', function() {
var data = {
pages: 0,
total:0
};
return data;
})
我的ctl 1:
.controller('patientCtl', ['$scope', '$http', 'patientListBarService', function($scope, $http, patientListBarService){
console.log(patientListBarService);
$scope.pages = patientListBarService.pages;
$scope.total = patientListBarService.total;
$scope.$watch('patientListBarService.pages', function(newVal, oldVal, scope) {
console.log('====pages:' + patientListBarService.pages);
$scope.pages = patientListBarService.pages;
});
$scope.$watch('patientListBarService.total', function(newVal, oldVal, scope) {
console.log('====total:' + patientListBarService.total);
$scope.total = patientListBarService.total;
});
}]);
my ctl 2:
controller('patientListCtl', ['$scope', 'patients', '$http', 'patientListBarService', function($scope, patients, $http, patientListBarService){
console.log("----patient list ctl----");
console.log(patients);
patientListBarService.pages = patients.config.pages;
patientListBarService.total = patients.config.total;
}]);
ctl1在ctl2之前运行。 在ctl2运行之后,ctl1' s
$scope.pages
$scope.total
在我的视图中显示正确的值。
然而,在我多次运行ctl2之后,它们的显示没有改变。
我是新手......
有人帮助我吗?谢谢!!!

如果将服务数据包装到对象中,则不需要监视,并且值将自动同步
.controller("Test1", function($scope, Serv){
$scope.serv = Serv.data;
$scope.modify = function(){
$scope.serv.param1 = Math.random()*100;
$scope.serv.param2 = Math.random()*100;
}
})
.controller("Test2", function($scope, Serv){
$scope.serv = Serv.data;
})
.factory("Serv", function(){
var data = {
param1: '',
param2: ''
}
return {
data: data
}
});
