Watching and Implementing DOM alterations in Angular: A Comprehensive Guide

When the button is clicked, a div containing <li> elements with images is created. The function being used is as follows:

<button data-ng-click="createWorkOrder()">Post project</button>

Function:

$scope.createWorkOrder  = function () {
    //API call to retrieve data
    $scope.myPromise = operationsFactory.readWorkOrders().success(function (response) {
        $scope.workOrdersList = response.result;
    })
};

Html:

<ul>
    <li dir-paginate="wd in workOrdersList | filter: search.status | filter: search.name | itemsPerPage: 10">
        <a href="">
            <h4>{{wd.name}}</h4>
        </a>
        <p>Status: {{wd.status}}</p>
    </li>
</ul>

Although the list is being generated, it requires a page refresh to be visible. I would like it to be displayed automatically once new data is fetched by the above function.

Answer №1

After creating this plunker to replicate your issue, everything ran smoothly without any errors.

Echoing what @claies mentioned earlier, "angular will automatically update the data unless you are neglecting to modify the values on either end". Have you made sure that you're updating the data correctly?

As demonstrated, once the request is complete, the list gets updated.
If your code still isn't functioning properly, consider invoking the $scope.$apply() method after the completion of your request; this action should refresh the bindings. Check out the $scope.$apply documentation for more information.

View:

<ul>
    <li dir-paginate="wd in workOrdersList | filter: search.status | filter: search.name | itemsPerPage: 5">
        <a href="{{wd.url}}">
            <h4>{{wd.name}}</h4>
        </a>
        <p>Status: {{wd.id}}</p>
    </li>
</ul>
<dir-pagination-controls></dir-pagination-controls>

Controller:

app.controller('MainCtrl', function($scope, $http) {

    // Replicating the issue
    $http({
        method: 'GET',
        url: 'https://api.github.com/repositories'
    }).then(function successCallback(response) {
       $scope.workOrdersList = response.data;
    }, function errorCallback(response) {

    });
});
