Run server-side code with google chart select - google-apps-script

Question

I have a google visualization table that I'm publishing in a web app.
Background:
I run a script that lists all the documents in a google folder in a spreadsheet. I then push that list into the google table I have published in the web app.
The need:
I want to manage those that same list of documents directly from the web app. I want to be able to to move the document from one folder to another when I select the applicable row on the table.
Two things I have accomplished:
I have a script that will move the document to a specific folder on
the google drive using it's doc id.
I have an event listener on the table so that when you click a row and
then click the delete icon, you get a prompt that asks, "are sure
you want to archive [enter document name]?" When I click ok, I get my
test prompt that says "document archived". When I click no, I get my
test prompt that says "request cancelled". So from this, I know I
have the appropriate code (at least that's how it seems).
What I'm struggling with:
I can't seem to get the codes above to work together. The event listener is providing me the url of the document which I have parsed to give me only the id. This is what I was hoping to use to get the rest of the code to run, but I think because I'm trying to interact with the server-side from the client-side, it's not working. Can anyone help me figure it out? I know that I need to use google.script.run.withSuccessHandler when running a server side script from the client side, but I don't know how it applies to this case the docid I need is being collected on table select. Any help is appreciated and I hope the above makes sense!
// Draw Dashboard
h2dashboard.bind([h2stringFilter, h2typeFilter], [h2chart]);
h2dashboard.draw(h2dataView);
google.visualization.events.addOneTimeListener(h2chart, 'ready', function() {
google.visualization.events.addListener(h2chart.getChart(), 'select', function() {
var selection = h2chart.getChart().getSelection();
var dt = h2chart.getDataTable();
// Get Value of clicked row
if (selection.length) {
var item = selection[0];
var docurl = dt.getValue(item.row, 1);
var docname = dt.getValue(item.row, 0);
var source = dt.getValue(item.row, 3);
// When button is clicked, show confirm box with value
$(document).ready(function() {
$("#hu2archive").on("click", function() {
var answer = confirm("Are you sure you want to archive " + docname + "?");
if (answer === true) {
var archive = DriveApp.getFolderById("FOLDER ID");
var docid = docurl.match(/[-\w]{25,}/); // This is where I'm grabbing the value from the row.
var doc = DriveApp.getFileById(docid);
doc.makeCopy(archive).setName(doc.getName());
source.removeFile(doc);
alert(docname + " has been archived!");
} else {
alert("Request cancelled");
}
});
});
}
});
});

I just got it! What I was having a hard time understanding was how to pass a variable from the client side to code.gs. I have only run a script in code.gs from the client side on button submit but never passed anything back.
So I ended up changing my code to the below which passes the variable I need into a successhandler where archiveDoc is the function in my code.gs and docurl is the name of the variable I need to pass from the eventlistener.
if (answer === true) { google.script.run.withSuccessHandler(onSuccess).withFailureHandler(err).archiveDoc(docurl);
I'm still new to coding so I just learned something new! So thanks Spencer Easton. I did in fact answer my own question.
