Can't able to Pass value from ajaxfunction to laravel api

I'm trying to pass the value to my backend(API developed using laravel 5.7) but I'm not able to pass the value. If I use button for submit then the value won't get passed, if I'm using "input" instead of "button" then being able to pass the value. and I'm not getting the response value. Any help for this issue is appreciated

    $.ajax({
        type: "POST", url: "localhost:8000/api/astroinfo", data: { username: $("#uname").val(), phonenumber: mob, email: $("#email").val() },
        success: function (data) {
            $("div").remove(".modal-body");
            if (data.status == '0') {
                $(".modal-header").after('<div id="errorID" class="alert alert-success">Successfully Submitted<br>We will revote you soon</div><div class="modal-footer"><button type="button" class="btn btn-info" data-dismiss="modal">Close</button></div>');
            } else if (data.status == '1') {
                $("modal-header").after('<div id="errorID" class="alert alert-danger">Something Went Wrong</div><div class="modal-footer"><button type="button" class="btn btn-info" data-dismiss="modal">Close</button></div>');
            }
        },
