Filtering data based on dates in AngularJS

Question

Filtering data based on dates in AngularJS

I need to implement a data filter based on event date. The options for filtering include the current day, current month, and current year. Below is the current implementation:

function filterDate($scope) {
    var d = new Date();
    var curr_date = d.getDate();
    var curr_month = d.getMonth();
    var curr_year = d.getFullYear();

    $scope.dateToday = Date.parse(curr_month + "/" + curr_date + "/" + curr_year);
    $scope.dateRange = ""; 

    $scope.dataModels = [
    {age:5,name:'John Lennon',eventDate:"1390524400000"},
    {age:12,name:'Nick Young',eventDate:"1377500400000"},               
    {age:10,name:'Mike Johnson',eventDate:"1374044400000"},
    {age:15,name:'Lisa Leslie',eventDate:"1335942000000"}
    ];

    $scope.eventDateFilter = function(column) {
        if(column === 'today') {
            $scope.dateRange = $scope.dateToday;
        } else if (column === 'currentWeek') {
            //need logic
        } else if (column === 'currnetMonth') {
           //need logic        
        } else if (column === 'currnetYear') {
            //need logic            
        }else {
            $scope.dateRange = "";
        }
    }
}

Here's how the controller looks like:

<div ng:controller="filterDate">
Date Filter
    <ul class="inline">
        <li><a href ng-click="eventDateFilter('all')">All</a></li>
        <li><a href ng-click="eventDateFilter('today')">Today</a></li>
        <li><a href ng-click="eventDateFilter('pastWeek')">Past Week</a></li>
        <li><a href ng-click="eventDateFilter('pastMonth')">Past Month</a></li>
    </ul>
    <table class="table">
        <tr>
            <th>Name</th>
            <th>Age</th>
            <th>Event Date</th>
        </tr>
        <tr ng:repeat="data in dataModels | filter:dateRange">
            <td>{{data.name}}</td>
            <td>{{data.age}}</td>
            <td>{{data.eventDate | date:medium}}</td>
        </tr>
    </table>    
</div>

Let me rephrase your query to ensure I address it accurately, as there seems to be some uncertainty:

You provided a list of objects with properties like
{age: <Number>, name: <String>, eventDate: <Timestamp>}
, and you wish to filter them based on the eventDate attribute. Specifically, you want to isolate objects within the current week.

To accomplish this, a slight adjustment in your Controller is necessary:

$scope.dateRanges = {
    all: {from: 0, to: Number.MAX_VALUE},
    // Functions getCurrent[Week,Month,Year]Range() will need to be defined by you,
    // This discussion (https://stackoverflow.com/questions/8381427/) provides insight
    week: getCurrentWeekRange(),
    month: getCurrentMonthRange(),
    year: getCurrentYearRange(),
};
$scope.currentDateRange = $scope.dateRanges.all; // set as the initial value
$scope.eventDateFilter = function(event) {
    return $scope.currentDateRange.from <= event.eventDate
        && event.eventDate <= $scope.currentDateRange.to;
});

Utilize the following approach in your template:

<ul>
    <li ng-click="currentDateRange = dateRanges.all">show all</li>
    <li ng-click="currentDateRange = dateRanges.week">show week</li>
    <li ng-click="currentDateRange = dateRanges.month">show month</li>
    <li ng-click="currentDateRange = dateRanges.year">show year</li>
</ul>
<table>
    <tr ng-repeat="data in dataModels | filter:eventDateFilter">
        <td>{{data.name}}</td>
        <td>{{data.age}}</td>
        <td>{{data.eventDate | date:medium}}</td>
    </tr>
</table>

An important distinction lies in changing the model upon navigation through ng-click, allowing Angular to update the view automatically.

This paradigm shift is crucial in Angular development, where the template reflects changes in the model without manual intervention, unlike traditional approaches involving jQuery or similar libraries.

Edit: `getCurrentDayRange()`

In response to comments about creating ranges (e.g., for the current day), refer to the method below inspired by this referenced solution.

function getCurrentDayRange() {
    // Return current day's start and end times
    return {
        from: new Date().setHours(0, 0, 0, 0), // Day begins at 00:00:00.000
        to: new Date().setHours(23, 59, 59, 999) // Day ends at 23:59:59.999
    };
}

Regarding when to invoke eventDateFilter: it is triggered automatically by the AngularJS digest loop, eliminating the need for manual execution. Review the Scope documentation for comprehensive insights.

If you want to simplify your date calculations, consider utilizing the power of moment.js library

function getTodayRange() {
    return {
        from: moment().startOf('day'),
        to: moment().endOf('day')
    };
} 
function getCurrentWeekRange() {
    return {
        from: moment().startOf('week'),
        to: moment().endOf('week') 
    };
};
function getCurrentMonthRange() {
    return {
        from: moment().startOf('month'),
        to: moment().endOf('month') 
    };
} 

function getCurrentYearRange() {
    return {
        from: moment().startOf('year'),
        to: moment().endOf('year') 
    };
}
