javascript - how can I make the client talk to the express server? -

so trying link interface server message input in front end posted in separate webpage hosted on server. eg "hello [name]"

this interface:

<form id="loginforma" action="userlogin" method="post"> <div>     <label for="insert message here">message: </label>     <input type="text" id="message" name="message"></input> </div> 

and server trying post message to:

 var express = require('express');   var app = express();   app.use(express.static('public'));   var bodyparser = require('body-parser');   app.use(bodyparser.urlencoded({ extended: true }));   app.use(bodyparser.json());   app.post("/userlogin", function(request, response) {  response.send( "hello " + request.body.message );     });   app.listen(process.env.port || 8080, process.env.ip); 

i not sure how make interface , server talk each other. store messages in db too, later after figure out.

thanks!

right form submits /userlogin. should define route in server this:

app.post('/userlogin', function(req, res){ res.send('hello' + req.body.message); } 

req.body post data submitted form, in case input named 'message.'

any time wish submit form node server, ensure action corresponds route or method identical name.
