AngularJS:如何获取模板的$ location.path [英] AngularJS: how can I get $location.path to template

问题描述

我需要模板中url的当前路径($ location.path的内容).但是不能通过控制器，因为我有很多控制器(并且我不想重复$scope.currentUrl = $location.path;的声明).感谢您的建议.

I need current path from url in template (content of $location.path). But not via controller, because I have a lot of controllers (and I do not want to duplicate declaration of $scope.currentUrl = $location.path;). Thanks for the advice.

推荐答案

AngularJS模板只能看到作用域中可用的内容，因此您将需要以某种方式将$ location服务放入作用域中. AngularJS应用程序中始终有一个名为$ rootScope的作用域，因此可以用于您的用例.

AngularJS template can only see what is available in a scope so you will need somehow to put $location service in a scope. There is one scope that is always available in AngularJS application called $rootScope so it could be use for your use-case.

您可以做的是使用模块的run()方法在$ rootScope中公开$ location:

What you could do is to use run() method of a module to expose $location in the $rootScope:

var myApp = angular.module('myApp', []).run(function($rootScope, $location) {
    $rootScope.location = $location;
});

这将使位置"在所有模板中均可用，以便以后可以在模板中使用:

this would make 'location' available in all templates so later on you could do in your template:

Current path: {{location.path()}}
