Discover the step-by-step process of retrieving an image through jQuery AJAX in Laravel 8

I'm facing an issue while trying to download images using jQuery/AJAX in Laravel 8. Although I am able to retrieve the image in the response, it isn't downloading as expected. Could someone please assist me in resolving this problem?

Controller

public function senddata(Request $req)
{
    $stamp = new Stamp();
    $stamp->company_name = $req->company_name;
    $stamp->reg_no = $req->reg_no;
    $stamp->color = $req->color;
    $stamp->fullname = $req->fullname;
    $stamp->email = $req->email;
    $stamp->save();
    
    $filepath = public_path('images/')."Screenshot_1.png";
        return Response::download($filepath);
}

jQuery/AJAX Code

$('#acceptform').submit(function () {
    if ($('#acceptform').valid()) {
        var company_name = $('#company_name').val();
        var reg_no = $('#reg_number').val();
        var color = $('input[name="stamp_color"]:checked').val();
        var fullname = $('#fullname').val();
        var email = $('#email').val();

        $.ajax({
            type: 'POST',
            url: "{{ route('senddata') }}",
            data: {company_name: company_name, reg_no: reg_no, 
                color: color, fullname: fullname, email: email},
            xhrFields: {
                responseType: 'blob'
            },
            success: function (res) {
                const data = res;
                const link = document.createElement('a');
                link.setAttribute('href', data);
                link.setAttribute('download', 'Screenshot_1.png');
                link.click();
            }
        });
    }
});

Answer №1

Is there a specific advantage to using Ajax for downloading files instead of just using a simple get request with the file ID?

Answer №2

If you find yourself in need of obtaining a file without ajax, you can still achieve this by fetching the desired file and then initiating a download using JavaScript.

For instance:

function initiateDownload(filePath) {
    let formData = new FormData;
    formData.append('file', filePath);    
    $.ajax({
        async: true,
        url: '{{ route("download") }}',
        type:"POST",
        data: formData,
        cache: false,
        processData: false,
        contentType: false,
        // specifying the response as a binary file
        xhrFields: { responseType: 'blob' },  
        success: function(downloadedFile) {
            var downloadLink = document.createElement("a");
            document.body.appendChild(downloadLink);
            downloadLink.style = "display: none";
            var fileUrl = window.URL.createObjectURL(downloadedFile);
            downloadLink.href = fileUrl;
            downloadLink.download = filePath;
            downloadLink.click();
            window.URL.revokeObjectURL(fileUrl);
        },
        error: function(errorResponse) {
            console.log(errorResponse);
        }
    }); 
}
