html data in blade file

this is my html data where resultContaineris id through which we display content and paginationContaineris for pagination through which we paginate using jquery

 <div class="row" id="resultContainer" style="margin-top:2%;">
    <div class="col-lg-12 col-md-12 col-sm-12 col-12">
        <div class="col-md-12 col-lg-12">

here i have taken admin_id based on user login i apply ternary condition

 <div class="col-6 p-3">
                    <label class="font-weight-bold text-danger"> Keyword</label>
                    <input type="text" class="form-control" name="manual_filter_table" id="filter_by_search" placeholder="Search Keyword.." style="font-size:18px; border:1px solid blue;">

loadData() Function:
Based on user login decide ajax route in jquery
Handles the initial data loading using AJAX.
Determines the URL based on the conditions.
Calls displayFilteredData to show the data.
Calculates total pages and calls addPaginationControls to update pagination.

var itemsPerPage = 5; // Set the number of items to display per page
    var currentPage = 1;  // Initial page

    // Initial load
    loadData();

    function loadData() {
        id = $('#admin_id').val();
        var isLoggedIn = $('#admin_id').val() !== '';
        var url = (id) ? '/all-influencer-data' : '/influencer-datas';

        console.log(url);

        if (url.includes('all-influencer-data')) {
            $.ajax({
                url: '/all-influencer-data',
                type: 'GET',
                success: function (data) {
                    console.log(data);
                    displayFilteredData(data);
                    var totalPages = Math.ceil(data.length / itemsPerPage);
                    addPaginationControls(totalPages);
                },
                error: function () {
                    console.log('Error loading data.');
                }
            });
        } else {
            console.log('Invalid URL');
        }
    }
Enter fullscreen mode Exit fullscreen mode

addPaginationControls() Function:

Generates pagination buttons based on the total number of pages.
Attaches a click event to each button to update the current page and reload data.

 function addPaginationControls(totalPages) {
        var paginationContainer = $('#paginationContainer');
        paginationContainer.empty();

        for (var i = 1; i <= totalPages; i++) {
            var button = $('<button>', {
                text: i,
                class: 'btn btn-sm btn-primary mr-2',
                click: function () {
                    currentPage = parseInt($(this).text());
                    loadData();
                }
            });

            paginationContainer.append(button);
        }
    }
Enter fullscreen mode Exit fullscreen mode

displayFilteredData() Function:

Clears the result container.
If data is available, displays it; otherwise, shows a message indicating no data.

Preventing Content Duplication:
common practice when dynamically updating content in a web application

resultContainer.empty();
Enter fullscreen mode Exit fullscreen mode

If you don't empty the container before appending new content, the new content will be added to the existing content, resulting in duplication. This is particularly important in scenarios where the data displayed can change dynamically, such as with AJAX requests.

function displayFilteredData(filteredData) {
        var resultContainer = $('#resultContainer');
        resultContainer.empty();

        if (filteredData.length > 0) {
            $.each(filteredData, function (index, item) {
                resultContainer.append('<p>' + item + '</p>');
            });
        } else {
            resultContainer.append('<p>No data found.</p>');
        }
    }

Another way

This part initializes variables for the current page and items per page. It then calls the loadData function to initiate the data loading process.

// Initial load
loadData();
Enter fullscreen mode Exit fullscreen mode 
var currentPage = 1;
var itemsPerPage = 10;
Enter fullscreen mode Exit fullscreen mode

The loadData function retrieves the value of admin_id and determines the URL based on its presence. It then makes an AJAX request to the appropriate URL, and on success, it calls the displayFilteredData function to handle the retrieved data.


function loadData() {
    var id = $('#admin_id').val();
    var isLoggedIn = $('#admin_id').val() !== '';
    var url = (id) ? '/all-influencer-data' : '/influencer-datas';
    console.log(url);

    if (url.includes('all-influencer-data')) {
        $.ajax({
            url: '/all-influencer-data',
            type: 'GET',
            success: function (data) {
                console.log(data);
                displayFilteredData(data);
            },
            error: function (error) {
                console.error('Error:', error);
            }
        });
    } else {
        $.ajax({
            url: '/influencer-datas',
            type: 'GET',
            success: function (data) {
                console.log(data);
                displayFilteredData(data);
            },
            error: function (error) {
                console.error('Error:', error);
            }
        });
    }
}
Enter fullscreen mode Exit fullscreen mode

The displayFilteredData function takes the retrieved data, checks if it contains filters, and then paginates the data based on the current page and items per page. It also updates the pagination controls and dynamically adds elements to the result container.

function displayFilteredData(data) {
    var resultContainer = $('#resultContent');
    resultContainer.empty();

    if (data && data.filters) {
        console.log("dfg");
        var filters = data.filters;
        console.log(filters);

        var startIndex = (currentPage - 1) * itemsPerPage;
        var endIndex = startIndex + itemsPerPage;
        var paginatedData = filters.slice(startIndex, endIndex);

        var totalPages = Math.ceil(filters.length / itemsPerPage);
        addPaginationControls(totalPages);

        if (paginatedData.length > 0) {
            $.each(paginatedData, function (index, item) {
                resultContainer.append('<p>' + item + '</p>');
            });
        } else {
            resultContainer.append('<p>No data found.</p>');
        }
    }
}
Enter fullscreen mode Exit fullscreen mode

The addPaginationControls function dynamically creates buttons for each page and attaches a click event to them. When a button is clicked, it updates the current page and triggers a data reload by calling the loadData function.

function addPaginationControls(totalPages) {
    var paginationContainer = $('#paginationContainer');
    paginationContainer.empty();

    for (var i = 1; i <= totalPages; i++) {
        var button = $('<button>', {
            text: i,
            class: 'btn btn-sm btn-primary mr-2',
            click: function () {
                currentPage = parseInt($(this).text());
                loadData();
            }
        });

        paginationContainer.append(button);
    }
}
Enter fullscreen mode Exit fullscreen mode 
var currentPage = 1;
var itemsPerPage = 5; // Set the number of items per page

function addPaginationControls(totalPages) {
    var paginationContainer = $('#paginationContainer');
    paginationContainer.empty();

    // Previous button
    paginationContainer.append('<button onclick="prevPage()">Previous</button>');

    // Page buttons
    for (var i = 1; i <= totalPages; i++) {
        paginationContainer.append('<button onclick="goToPage(' + i + ')">' + i + '</button>');
    }

    // Next button
    paginationContainer.append('<button onclick="nextPage()">Next</button>');
}

function prevPage() {
    if (currentPage > 1) {
        currentPage--;
        displayFilteredData(data);
    }
}

function nextPage() {
    var totalPages = Math.ceil(data.length / itemsPerPage);
    if (currentPage < totalPages) {
        currentPage++;
        displayFilteredData(data);
    }
}

function goToPage(page) {
    currentPage = page;
    displayFilteredData(data);
}
Enter fullscreen mode Exit fullscreen mode 
function displayFilteredData(data) {
    var resultContainer = $('#resultContent');
    resultContainer.empty();

    if (data.length > 0) {
        var startIndex = (currentPage - 1) * itemsPerPage;
        var endIndex = startIndex + itemsPerPage;
        var paginatedData = data.slice(startIndex, endIndex);

        var cardContent = '';
        $.each(paginatedData, function(index, item) {
            cardContent += '<div class="card-content">';
            cardContent += '<p>ID: ' + item.id + '</p>';
            cardContent += '<p>Payment ID: ' + item.payment_id + '</p>';
            cardContent += '</div>';
        });

        resultContainer.append(cardContent);
        var totalPages = Math.ceil(data.length / itemsPerPage);
        addPaginationControls(totalPages);
    } else {
        resultContainer.append('<p>No data found.</p>');
    }
}

// Call initial display
displayFilteredData(data);
