问题描述

我想设置类。主动时,路径是的http://本地主机/#/ 的http://本地主机/#/主/ 为两条路径在同一页

I am trying to set the class .active when the path is http://localhost/#/ or http://localhost/#/main/ as both paths are the same page.

为什么纳克级={'class1的':前pression1,1级:前pression2}?不行

控制器

angular.module('testApp')
  .controller('NavmenuCtrl', function ($scope, $location) {
  $scope.isActive = function (providedPath) {
    return providedPath === $location.path();
  };
});

局部模板视图

<li ng-class="{ active: isActive('/'), active: isActive('/main/')}">
  <a href="#/">Home</a>
</li>

添加多个类

推荐答案

让我评论的回答,是你的问题出在重复键,你可以只是做: -

Making my comment an answer, Yes your issue is with the duplicate keys, you could just do:-

ng-class="{ active: isActive('/') || isActive('/main/')}"

或者可能更好: -

Or probably better:-

让你的 isActive 类接受多个参数: -

Let your isActive class accept multiple arguments:-

$scope.isActive = function () {
    //Look for a match in the arguments array
    return [].indexOf.call(arguments, location.path()) > -1;
};

和使用它作为: -

and use it as:-

ng-class="{ active: isActive('/', '/main/')}"

的indexOf 沉支持旧的浏览器

Shim support for indexOf for older browsers
