Ajax based File upload using Form data not working in laravel | Learning Curve- Perfect Tutorial for the beginers

Below is my ajax code to upload the file

$('.fileupload').on('change',function(){    
        var formObj = $('#myForm');
        var formData = new FormData(formObj[0]);
        $.ajax({
            url: siteUrl+'/getmydata',
            async: true,
            type: "POST",
            data: formData,
            dataType: "json",
            success: function (data)
            {
                alert(data.count);
               
            }

        });
     });

$('.fileupload').on('change',function(){

var formObj = $('#myForm');

var formData = new FormData(formObj[0]);

$.ajax({

url: siteUrl+'/getmydata',

async: true,

type: "POST",

data: formData,

dataType: "json",

success: function (data)

{

alert(data.count);

}

});

Please add the below code to work the fileupload proper

<script type="text/javascript">
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        }
    });
</script>

$.ajaxSetup({

headers: {

'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')

}

});

</script>

if the issue still exists add the following extra things in the ajax call

url: siteUrl+'/get_gstrefno_from_excel',
            async: true,
            type: "POST",
            data: formData,
            dataType: "json",
			
            contentType: false,
            cache: false,
            processData: false,

url: siteUrl+'/get_gstrefno_from_excel',

async: true,

type: "POST",

data: formData,

dataType: "json",

contentType: false,

cache: false,

processData: false,
