    var data = [];

    for (var index = 0; index < 1; index++) {

        $('#mytableform1').each(function (_, element) {

            var element = document.getElementsByName("namesavedata[]");

            for (var i = 0; i < element.length; i++) {

                data.push(element[i].value);
            }
           

        });

        
        var result = [];

        for(var i = 0; i < data.length; i++) {

            var obj = {}

            obj= data[i];

            result.push(obj)
