角度过滤器不工作过滤器不显示类别值

Question

我正在添加过滤器以显示类别，但我的setCurrentCategory函数未显示任何值显示未定义。我想为每个人展示类别。我使用ng-click并传递my函数，而不是使用filter并传递值。

var myapp = angular.module("myapp", []);
myapp.controller("myCtrl", function($scope){

$scope.categories = [

{'id' : 0, 'Name' : 'Manu'},
{'id' : 1, 'Name' : 'Rajveer'},
{'id' : 2, 'Name' : 'Heament'},
{'id' : 3, 'Name' : 'Yogesh'},
{'id' : 5, 'Name' : 'Sajid'},


];

$scope.languages = [
{'id' : 0, 'title' : 'Angular', 'url' : 'http://angularjs.org', "category": "Manu"},
{'id' : 0, 'title' : 'Html5', 'url' : 'http://www.html5rocks.com/en/', "category": "Manu"},
{'id' : 0, 'title' : 'BootStrap', 'url' : 'http://getbootstrap.com/', "category": "Rajveer"},
{'id' : 0, 'title' : 'Css', 'url' : 'http://www.tutorialspoint.com/css/', "category": "Yogesh"},
{'id' : 0, 'title' : 'emberjs', 'url' : 'http://emberjs.com/', "category": "Heament"},
{'id' : 0, 'title' : 'Javascript', 'url' : 'https://www.javascript.com/', "category": "Rajveer"},
{'id' : 0, 'title' : 'jQuery', 'url' : 'https://jquery.com/', "category": "Yogesh"},
{'id' : 0, 'title' : 'Photoshop', 'url' : 'http://www.photoshop.com/', "category": "Sajid"},
{'id' : 0, 'title' : 'Coral Draw', 'url' : 'http://www.coreldraw.com/in/', "category": "Heament"},
{'id' : 0, 'title' : 'Flash', 'url' : 'https://get.adobe.com/flashplayer/', "category": "Sajid"},

];

$scope.currentCategory = null;

function setCurrentCategory(category){

	$scope.currentCategory = category;
}

function isCurrentCategory(category){

	return $scope.currentCategory !== null && category.name === $scope.currentCategory.name;
}

$scope.setCurrentCategory = setCurrentCategory;
$scope.isCurrentCategory = isCurrentCategory;

});

Answer 1

确保您传递category对象：

<li ng-repeat='category in categories'> // changed to 'category'
            <a href="#" ng-click="setCurrentCategory(category)">{{category.Name}}</a>
            </li>

Answer 2

<ul>
<li ng-repeat='categorie in categories'>
<a href="#" ng-click="setCurrentCategory(category)">{{categorie.Name}} </a>                   
</li>           
</ul>

我需要传递类别

<ul>
<li ng-repeat='categorie in categories'>
<a href="#" ng-click="setCurrentCategory(categorie )">{{categorie.Name}}</a>                      
</li>           
</ul>

Answer 3

在您的代码中，您必须使用ng-repeat中使用的相同引用传递给Setcurrentcategory函数。他们必须匹配。

<li ng-repeat='category in categories'> 
        <a href="#" ng-click="setCurrentCategory(category)">{{category.Name}}</a>
        </li>
