AngularJS:访问 $routeProvider 中的范围变量 [英] AngularJS: accessing scope variables in $routeProvider
问题描述
我在 JSP 页面上有一个 Angular 应用程序，它具有:
I have an angular app on a JSP page that has:
ng-init="role='<%=String.valueOf(session.getAttribute("role"))%>'"
因此当 JSP 从会话中拉取角色属性时，body 标记将如下所示:
So the body tag will look like this when the JSP pulls the role attribute from the session:
<body ng-app="appName" ng-init="role='roleName'">
我想访问 $routeProvider 中的这个 role 变量.
I want to access this role variable in the $routeProvider.
我尝试通过将 $scope 传递给 app.config 函数来这样做:
I tried doing so by passing $scope to the app.config function as such:
app.config(['$routeProvider', '$scope',
function ($routeProvider, $scope) {
$routeProvider
.when('somePath' {
...
})
.when('someOtherPath' {
...
})
.otherwise({
redirectTo: $scope.role == 'goodRole' ? 'somePath' : 'someOtherPath'
});
}]);
但是，您似乎无法以这种方式传入 $scope.
However, it appears that you cannot pass in the $scope that way.
有没有办法以这种方式访问作用域变量，或者有其他方法可以实现这一点?
Is there a way to access a scope variable in this fashion, or is there another way to accomplish this?
推荐答案
不，这是不可能的.如何将它设置为 data-role 属性并从 document.body.dataset.role 获取它:
Nope, it is not possible. How about you set it to a data-role attribute and get it from document.body.dataset.role:
data-role="<%=String.valueOf(session.getAttribute("role"))%>"
