Question

变量字符串的更改无法正常工作

var angulargap = angular.module("angulargap", []);
angulargap.factory('cartService', function($rootScope,$http){    
    var fac ={
        message:"factory",
        getCart:function(call){
            $http.post("/rpc.php", {app:"get_cart",pag:"cart"})
            .success(function(data, status, headers, config) {
                fac.setMessage("success");      
            }).error(function(data, status, headers, config) {

            });

        },
        setMessage:function(m){fac.message=m;} 
    }
    return fac; 
});
angulargap.controller("iridium", function ($scope,cartService){     
    cartService.getCart();  
    $scope.message=cartService.message;
});

相反，更新数组一切正常怎么了？感谢

Answer 1

替换此行

 setMessage:function(m){fac.message=m;}

与

 setMessage:function(m){message=m;}

我通过用对象

更改字符串变量来解决它

var angulargap = angular.module("angulargap", []);
angulargap.factory('cartService', function($rootScope,$http){    
    var fac ={
        messages:{cartnum:"0"},
        getCart:function(call){
            $http.post("/rpc.php", {app:"get_cart",pag:"cart"})
            .success(function(data, status, headers, config) {
                fac.setCounter("num from server");      
            }).error(function(data, status, headers, config) {

            });

        },
        setCounter:function(m){fac.messages.cartnum=m;} 
    }
    return fac; 
});
angulargap.controller("iridium", function ($scope,cartService){     
    cartService.getCart();  
    $scope.messages=cartService.messages;
});

现在一切正常，我在前端看到了结果如果我使用字符串变量，有人可以向我解释为什么它不起作用吗？

我明白了：

{{messages.cartnum}}

未检测到角度变化
