How to post to Google docs using a jQuery ajax POST request

gistfile1.js

// url is the link for the form view page
// data is the name attribute of the field


$.ajax({
    url: "https://docs.google.com/forms/d/1iqMixtVq4O0AFvYCZHbGerigi1G5Qb3XthXZX9VpNtk/formResponse",
    data: { "entry.1679407376": field1},
    type: "POST",
    dataType: "xml",
    statusCode: {
        0: function() {
            //Success message
        },
        200: function() {
            //Success Message
        }
    }
});

vanilla.js

var request = new XMLHttpRequest();
var d = new Date();
var n = d.getTime();
var url = 'https://docs.google.com/forms/d/1FhRXyqVohna2IdThVwONXLAAGW4f6Ioy46BR2MRZy68/formResponse';
var data = { "entry.993789377": n};
request.open('POST', url, true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
request.send(data);

after creating form click three dots> go to get prefilled link>then inspect
you will get the input fields name

I'm surprised people still use this!
