"Encountering problem with sending data to server through Ajax

I am facing a very complex issue that requires an in-depth understanding. If this interests you, please continue reading.

I have developed a program from scratch that generates an HTML page for user data input and submission. The submitted data is sent to a local node.js server that simply logs it to the console. The data is passed through a querystring in the URL, such as

http://localhost/?<parametersGoHere>
. The client files are hosted using the node.js module http-server, which can be found at https://github.com/nodeapps/http-server.

The problem I am facing is that the ajax call to the node.js server fails every time. I can manually enter the URL with parameters and get the expected results, but the ajax call does not work as expected. I suspect the issue lies within the network.js file. Can anyone help me identify and solve this error?



Below is the code for the node.js server:

(server.js file content goes here)


The following are the scripts running on the HTML page:

(scripts.js content goes here)


Here is the HTML content of the page:

(HTML content goes here)


Lastly, here is the network.js code which is called when the submit function is triggered:

(network.js content goes here)



I understand that this is a lengthy amount of code. Please feel free to provide feedback on how I can make it more understandable or readable. Leave a comment if you need any clarification.

It is recommended to serialize an object rather than manually constructing the query string:

const userData = {
    name: "Alice",
    occupation: "Developer",
    joinDate: "12-15-2021",
    status: "Active",
    location: "Lat: 12345 Long: -67890 Alt: N/A"
};

$.ajax({
    type: "POST",
    url: "http://localhost/api",
    data: userData,
    success: function () {
        clearForm();
    },
    error: function() {
        saveLocally();
        alert("Failed to establish connection with the server.");
    }
});
