Tips for showcasing a restricted amount of data with Angular.js

I've been exploring different ways to limit the results using limitTo, but unfortunately, I'm encountering unexpected issues. Currently, the entire list is being displayed when I only want to show 8 key-value items in a 4/4 block format.

You can check out the code on this plnkr link.

  
<ul>
    <li ng-repeat="(key,value) in stocks |limitTo :8">
        {{key +" "+ value}}
    </li>
</ul>

<script>
var app = angular.module('smallcaseApp', []);
app.controller('stockCtrl', function($scope, $http) {
$http.get("data.json").then(function(response) {
$scope.stocks = response.data.price;
});
});
</script> 

Answer №1

When using limitTo, the input should consist of an array or a string/number. To address this, you will need to create a custom filter. Below is a functional plunk that can help resolve your issue.

app.filter('objLimitTo', [function(){
return function(obj, limit){
    if(obj){
      var keys = Object.keys(obj);
      if(keys.length < 1){
        return [];
      }
    }

    var result = {},
    count = 0;
    angular.forEach(keys, function(key){
        if(count >= limit){
            return false;
        }
        result[key] = obj[key];
        count++;
    });
    return result;
};
}]);

Answer №2

Initially, it appears that your plunkr is experiencing issues and the angular js link should be placed above any other js scripts (specifically your app js).

You are currently iterating through an Object, but for implementing limitTo functionality, there is a well-executed example available for reference. Feel free to check out this resource: SO Link
