function show_order() {

$.ajax({
type: 'GET',
url: '/mars',
data: {},
success: function (response) {
alert(response['msg'])
}
});
}
function save_order() {
    let name = $('#name').val()
    let address = $('#address').val()
    let size = $('#size').val()
}
$.ajax({
    type: 'POST',
    url: '/mars',
    data: { name_give: name, address_give: address, size_give: size},
    success: function (response) {
        alert(response['msg'])
        window.location.reload()
    }
});  /구문이 필요하다고 뜹니다 
}

let name. address .size 가 안먹힙니다

def web_mars_post():
    name_receive = request.form['name_give']
    address_receive = request.form['address_give']
    size_receive = request.form['size_give']
    doc = {
        'name' : name_receive,
        'address' : address_receive,
        'size' : size_receive
    }
    db.mars.insert_one(doc)

    return jsonify({'msg': '주문완료!'})

    @app.route("/mars", methods=["GET"])
    def web_mars_get():
        return jsonify({'msg': 'GET 연결 완료!'})

서버쪽 코드입니다
