I am trying to initiate a POST request in javascript/jquery so that FLASK can carry out its function of processing and uploading user input data in form.

#CATALOG
@app.route("/catalog", methods=["POST","GET"])
def catalog():
    if request.method =="POST":
           #function loads form data to mongodb with processing

This is my javascript main.js

$(document).ready(function(){
    //On Submit
    $("#form").on('submit',function(e){
        e.preventDefault();
        $.ajax({
            type:'POST', url:'/catalog',
            success: function(years){
                console.log("Form data loaded to mongodb")}
            });

Is it possible to initiate a POST method via javascript with out refreshing the page?
