"Enhancing Webpages with AngularJS: The Power of Binding and Re

Using AngularJS to load AJAX content and ng-repeat to generate a list of items. I have a placeholder {{noun}} in the content, expecting it to be replaced with data from $scope.noun when the AJAX content is loaded. However, this does not happen automatically. Is there a quick and easy way to achieve this?

Below is the code snippet:

AllControllers.controller('AppController', ['$scope', '$http', function ($scope, $http) {

    $scope.noun = "My Noun";

    $scope.headlines = [{
        headline: "Top 10 Tricks to {{noun}}",
        usage: 10,
        votes: 100
    }];

    $scope.load_headlines = function() {
        $http.get('/data/headlines.json').
            success(function(data, status, headers, config){
                $scope.headlines = data;
            }).
            error(function(data, status, headers, config){
                console.log(status);
            });
    };
    }]);

<div ng-controller="AppController" ng-init="load_headlines()">

    <table>
    <tbody ng-repeat="headline in headlines">
    <tr>
        <td>{{headline.headline}}</td>
        <td class="center">{{headline.usage}}</td>
        <td class="center">{{headline.votes}}</td>
    </tr>
    </tbody>
    </table>

</div>

Answer №1

The $scope variable you are using is different from the ngRepeat variable. Consider updating the $scope variable in your controller:

$scope.headlines_displayed = [{
        headline: "Top 10 Tips for "+$scope.noun,
        usage: 10,
        votes: 100
    }];

Answer №2

you can encapsulate the {{moon}} within the td element multiple times.

modify the code as shown below:

AllControllers.controller('AppController', ['$scope', '$http', function ($scope, $http) {

    $scope.noun = "My Noun";

    $scope.headlines = [{
        headline: "Top 10 Tricks to ",
        usage: 10,
        votes: 100
    }];
}]);

<tbody ng-repeat="headline in headlines_displayed">
<tr>
    <td>{{headline.headline}} {{noun}}</td>
    <td class="center">{{headline.usage}}</td>
    <td class="center">{{headline.votes}}</td>
</tr>
</tbody>

Answer №3

Finally solved the problem by implementing the following solution:

<td>{{headline.headline.replace("{{word\}\}", word)}}</td>

Answer №4

When dealing with AngularJS, it is important to use the $interpolate service to compile strings before assigning them to the scope. Simply passing a string with double curly braces {{}} will not work as expected. In your http success callback, implement something similar to the following code snippet. This will ensure that your variable references are replaced with actual scope values.

 $scope.load_headlines = function() {
    $http.get('/data/headlines.json').
        success(function(data, status, headers, config){
            $scope.headlines = data;
            $interpolate($scope.headlines.headline)($scope);
        }).
        error(function(data, status, headers, config){
            console.log(status);
        });
};
}]);
