我如何获得$ routeParams自定义指令内

问题描述

我创建一个导航栏的指令，我想用$ routeParams确定要设置为激活哪个环节。我可以访问$ routeParams在控制器没有问题：

I am creating a navBar directive and I would like to use $routeParams to determine which link to set to active. I can access $routeParams in controllers with no problem:

app.controller('MovieDetailsController', ['$scope', '$http', '$routeParams', function ($scope, $http, $routeParams) {
        $scope.movie = {};
        console.log($routeParams);
    }]);

不过，我无法从$在我的指令routeParams得到任何数据：

However, I am unable to get any data from $routeParams in my directive:

app.directive('navBar', ['$routeParams', function ($routeParams) {
        console.log($routeParams);
    }]);

我在做什么错了？

What am I doing wrong?

推荐答案

好像当指令初始化$ routeParams不可用等。如果你使用的指令如下面作为普拉克它应该工作。

Seems like when the directive is initialized $routeParams is not available. If you use the directive like below as in the plunk it should work.

app.directive('myDir', ['$routeParams', function ($routeParams) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs) {
        element.bind('click', function() {
          alert($routeParams.number);
        });
      }
    }
  }]);
