I'm making a basic program where the user is shown a current room temperature along with a text field and "Set" button so that they can set their desired room temperature. What I want to happen is when the user enters a number into the text field and hits the Set button it changes the "roomTemp" variable to their desired temperature also known as "desiredTemp" and displays it as the current temperature. I don't think it's reaching the save() function as nothing is printed in my console when the button is clicked when it should output "Temperature is changing!" to my console.
Javascript File:
var http = require('http');
var ejs = require('ejs');
var fs = require('fs');
var roomTemp = 20;
var desiredTemp = 0;
http.createServer(function(req,res) {
res.writeHead(200, {'Content-Type': 'text/html'});
//since we are in a request handler function
//we're using readFile instead of readFileSync
fs.readFile('index.html', 'utf-8', function(err, content) {
if (err) {
res.end('error occurred');
return;
}
var renderedHtml = ejs.render(content, {roomTemp: roomTemp}); //get redered HTML code
res.end(renderedHtml);
});
}).listen(3000, "127.0.0.1");
console.log('Server Running at http://127.0.0.1:3000 CNTL-C to quit');
HTML File:
<!DOCTYPE html>
<html>
<head>
<script src="Thermostat.js"></script>
</head>
<body>
Current Temp: <%= roomTemp %> <br></br>
<form>
Desired Room Temperature: <input type="number" id="desTemp" name="roomTempDes"><br></br>
<button onclick="save(document.getElementById("roomTempDes").value)">Set</button>
</form>
<script>
function save(desiredTemp) {
roomTemp = desiredTemp;
console.log("Temperature is changing!");
}
</script>
</body>
</html>
model.temperatureand the UI changes.
