Question

我需要在ajax调用后在服务工厂中保存数据。这一切都没有location.href。但是当我输入行代码$ window.location.href时它不起作用。这是代码：

 scope.res = function(id){
            factoryService.getLista(id,"en-US","") 
            .then (function(response){commonVarService.setA(response.A);
                                      commonVarService.setB(response.B);
                                      commonVarService.setC(response.C);
                                      $window.location.href="./menu/menu.html";
                                     })
            .catch(function(err)  {console.log(err)});
        };

其中，factoryService允许进行ajax调用，而commonVarService允许在服务变量中记忆数据。如果没有$ window.location.href =＆＃34;＆＃34;这一切都有效，但是当有$ window.location.href时，应用程序在新页面中重定向而不记住变量。我错在哪里？有一些好的解决方案吗？提前谢谢。

commonVarService代码是这样的：

angular.module（＆＃39; common_variable＆＃39;，[]）。服务（＆＃39; commonVarService＆＃39;，函数（）{

        /*a*/
        this.getA = function(){
            return this._a;
        }

        this.setA = function(a){
            return this._a=a;
        }

        /*b*/
        this.getB = function(){
            return this._b;
        }

        this.setB = function(b){
            return this._b = b;
        }

        /*c*/
        this.getC = function(){
            return this._c;
        }

        this.setC = function(c){
            return this._c = c;
        }

});

我还试图只将字符串作为参数：

commonVarService.setA（＆＃34; A＆＃34）; commonVarService.setB（＆＃34; B＆＃34）; commonVarService.setC（＆＃34; C＆＃34）

但是当我在href链接的新page.html中时，变量A，B，C未定义......我不知道..

谢谢你的支持！

So, I am explaining the problem here, When you are using$window.location.href = 'something' . It does a full page refresh, so it cannot store the variable,reinstatiate a new angular instance. i would suggest to use , angular-route or angular-ui-router , where you can change the route by using this , $location.path('/profile') or $location.path('/mypage') if you are building a SPA(Single page application) ,which will retain the state of your page.

Issue is with scope of variables when you are changing current page location it will load all js files again so it will also declare new variables

"var service={}; var _a = null; var _b = null; var _c = null;"

Define above variables in "localstorage"

i.e. to Set Value : localStorage.setItem("_a ", a);
to Get Value : localStorage.getItem("_a");

在AngularJS中调用ajax后执行服务
