使用数据库中的数据填充数组（Angular + PHP / MySQL）

我正在使用一个简单的待办应用程序，该应用程序使用Angular，然后使用PHP / MySQL作为后端。

我现在有一个简单的应用程序，可以在其中运行，可以添加新的待办事项，并使用simple每天将“已完成的百分比”添加到数据库中$http post。

但是现在我要做的是$scope.historicalDailyPercentages用数据库中的数据填充数组。

在脚本开始时，我将对象初始化为：

$scope.historicalDailyPercentages = []; //TODO, this should be initialised with data from the database.

我知道我需要在其中有某种$ http get循环，以检查数据并填充对象，但是我不清楚如何开始于此。

整个goalzy.js脚本在下面供参考。提前致谢！

angular.module('goalzy', [])

.config(['$httpProvider', function($httpProvider) {
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/json; charset=utf-8';
}])

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

    $scope.todos = [];
    $scope.historicalDailyPercentages = []; //TODO, this should be initialised with data from the database.

    $scope.addTodo = function() {
        if ($scope.todoText != "") {
            if ($scope.todos.length < 3) {
                $scope.todos.push({
                    text: $scope.todoText,
                    done: false
                });
                $scope.todoText = '';
                //Save to DB
            } else {
                alert("You can only have 3 todos per day!");
                $scope.todoText = '';
            }
        } else {
            alert("you must write something");
        }
    };

    $scope.remaining = function() {
        var count = 0;
        angular.forEach($scope.todos, function(todo) {
            count += todo.done ? 0 : 1;
        });
        return count;
    };

    $scope.percentComplete = function() {
        var countCompleted = 0;
        angular.forEach($scope.todos, function(todo) {
            countCompleted += todo.done ? 1 : 0; //Simply calculates how many tasks have been completed
            console.log(countCompleted);
        });
        var totalCount = $scope.todos.length;
        var percentComplete = countCompleted / totalCount * 100;
        return percentComplete;
    }

    $scope.finaliseDay = function(percentComplete) {
        alert("You're finalising this day with a percentage of: " + percentComplete);
        var today = new Date();
        var alreadyPresent = $scope.historicalDailyPercentages.some(function(item) {
            return item.date.getFullYear() === today.getFullYear() &&
                item.date.getMonth() === today.getMonth() &&
                item.date.getDate() === today.getDate();
        });

        //Confirm that nothing has alreayd been posted for today
        if (!alreadyPresent) {

            // Simple POST request example (passing data)
            $http.post('/postDailyPercentage.php', {
                user_id: 1,
                percent: percentComplete,
                date: today
            }).
            success(function(data, status, headers, config) {
                // this callback will be called asynchronously
                // when the response is available
                if (data) {

                    $scope.historicalDailyPercentages.push({
                        user_id: 1,
                        percent: percentComplete,
                        date: today
                    });

                } else {
                    alert("Something went wrong" + data);
                }

            }).
            error(function(data, status, headers, config) {
                // called asynchronously if an error occurs
                // or server returns response with an error status.
                console.log("Post failure");
            });
        } else {
            alert("You're all set for today - see you tomorrow!");
        }

        //console.log($scope.historicalDailyPercentages);
    }
}]);

要用$ http.get填充该对象，您可以按如下操作：

function getHistoricalDataSuccess(data) {
  $scope.historicalDailyPercentages = data;
}

function getHistoricalDataError(error) {
  //handle the error
}

$http.get('path/to/api')
.success(getHistoricalDataSuccess)
.error(getHistoricalDataError);
