Question

我正在尝试在选择时添加两个页面的值。它正在添加单个页面。但是当我移动到下一页时，总值为零。我正在尝试将传递总增值从一个页面添加到另一个页面。在我搜索时，我发现需要创建一个服务控制器来调用全局范围值。

我可以在这里看到两个问题。

您正在每个控制器初始化$ rootScope.selection = []，这将删除所有先前的更改。在运行块内的页面加载开始时初始化它。使用此链接实现运行run。

myApp.run(function() { console.log("app run"); });

您没有将所选数据传输到$ rootScope.selection变量。您需要在rootScope中附加所选产品，并确保不重复任何项目。我推荐你使用带有'ids'作为attrinute名称的对象而不是数组，这将确保没有任何项目本身重复。
