Node.js Routing ajax requests with Express.JS A simple implementation of AJAX
Example
You should have the basic express-generator template
In app.js, add(you can add it anywhere after var app = express.app()):
app.post(function(req, res, next){
next();
});
Now in your index.js file (or its respective match), add:
router.get('/ajax', function(req, res){
res.render('ajax', {title: 'An Ajax Example', quote: "AJAX is great!"});
});
router.post('/ajax', function(req, res){
res.render('ajax', {title: 'An Ajax Example', quote: req.body.quote});
});
Create an ajax.jade / ajax.pug or ajax.ejs file in /views directory, add:
For Jade/PugJS:
extends layout
script(src="http://code.jquery.com/jquery-3.1.0.min.js")
script(src="/magic.js")
h1 Quote: !{quote}
form(method="post" id="changeQuote")
input(type='text', placeholder='Set quote of the day', name='quote')
input(type="submit", value="Save")
For EJS:
<script src="http://code.jquery.com/jquery-3.1.0.min.js"></script>
<script src="/magic.js"></script>
<h1>Quote: <%=quote%> </h1>
<form method="post" id="changeQuote">
<input type="text" placeholder="Set quote of the day" name="quote"/>
<input type="submit" value="Save">
</form>
Now, create a file in /public called magic.js
$(document).ready(function(){
$("form#changeQuote").on('submit', function(e){
e.preventDefault();
var data = $('input[name=quote]').val();
$.ajax({
type: 'post',
url: '/ajax',
data: data,
dataType: 'text'
})
.done(function(data){
$('h1').html(data.quote);
});
});
});
And there you have it! When you click Save the quote will change!
