AngularJS-ng-show无法正常工作

Question

I'm trying to hide to <a> tags, and then show them when I'm logged in, using the isLoggedIn() function, but the <a> tag is showing no matter what.

HTML (pool-details.html)

<header class="hero-unit" id="banner" ng-include="'components/header/header.html'"></header>

<div ng-include="'components/navbar/navbar.html'"></div>

<div class="container"> <hr>
    <div class="col-md-3 left-col-3">  
        <div ng-include="'../components/sidebar/sidebar.html'"></div>
    </div>

    <div class="col-md-5">
        <div class="details-pic">
            <img class="pool-details-pic" ng-src="{{ pool.picture }}"/>
        </div>
    </div>

    <div class="col-md-4">
        <h3 class="details-name">{{ pool.name }}</h3>
        <p class="details-info">Varenummer: {{ pool.number }}</p>
        <p class="details-info">Lager status: {{ pool.inStock }}</p>
        <p class="details-info">Dimensioner: {{ pool.width }}m x {{ pool.length }}m x {{ pool.height }}m</p>
        <hr>
        <p class="details-info">{{ pool.info }}</p>
    </div>
    <div class="col-md-12">
        <a ng-show="'isLoggedIn()'" ng-click="deleteProduct(pool)" class="delete-product">Slet</a>
        <a ng-show="'isLoggedIn()'" ng-click="editProduct(pool)" class="edit-product">Opdater</a>
    </div>

</div>

<footer class="footer" ng-include="'components/footer/footer.html'"></footer>

CONTROLLER (pool-details.controller.js)

'use strict';

angular.module('welldanaJavascriptApp')
    .controller('poolDetailsCtrl', function ($scope, $stateParams, $state, poolService, Auth) {

        $scope.pool = {};
        poolService.find($stateParams.poolId, function(pool) {
             $scope.pool = pool;
        });

        $scope.deleteProduct = function(product){
            poolService.delete(product._id, function(){
                $state.go('pools');   
            });
        };
});

I can't wrap my head around why the <a> tag is still showing, though I'm not logged in. I'm using the Passport plugin for an Angular fullstack application.

Answer 1

ng-show="'isLoggedIn()'"

它会计算'isLoggedIn（）'字符串，并且始终为true，因此您应将其重构为ng-show="isLoggedIn()"

Answer 2

Okay I managed to sort out my problem. It was a simple rookie mistake from my hand, my apologies.

Solution

I was missing the $scope.isLoggedIn()

I simply addes this to the controller:

$scope.isLoggedIn = function(){
    return Auth.isLoggedIn();
}

And just returning the Auth.isLoggedIn() to actually add this value to my scope, thereby being able to check it in the HTML.
